+name: Reimplementation Questions
+about: Ask about questions during model reimplementation
+title: ''
+labels: reimplementation
+assignees: ''
+---
+
+**Notice**
+
+There are several common situations in the reimplementation issues as below
+
+1. Reimplement a model in the model zoo using the provided configs
+2. Reimplement a model in the model zoo on other dataset (e.g., custom datasets)
+3. Reimplement a custom model but all the components are implemented in HunyuanDiT
+4. Reimplement a custom model with new modules implemented by yourself
+
+There are several things to do for different cases as below.
+
+- For case 1 & 3, please follow the steps in the following sections thus we could help to quick identify the issue.
+- For case 2 & 4, please understand that we are not able to do much help here because we usually do not know the full code and the users should be responsible to the code they write.
+- One suggestion for case 2 & 4 is that the users should first check whether the bug lies in the self-implemented code or the original code. For example, users can first make sure that the same model runs well on supported datasets. If you still need help, please describe what you have done and what you obtain in the issue, and follow the steps in the following sections and try as clear as possible so that we can better help you.

+about: 询问模型复现中的问题
+title: ''
+labels: reimplementation
+assignees: ''
+---
+
+**注意**
+
+在复现的问题中，通常有以下几种常见情况：
+
+1. 使用提供的配置复现模型库中的模型
+2. 在其他数据集（例如自定义数据集）上复现模型库中的模型
+3. 实现自定义模型，但利用的都是HunyuanDiT中实现的组件
+4. 使用自己实现的新模块实现自定义模型
+
+针对不同情况需要做的事情如下：
+
+- 对于情况 1 和 3，请按照以下部分的步骤操作，以便我们快速识别问题。
+- 对于情况 2 和 4，请理解我们无法提供太多帮助，因为我们通常不了解全部代码，用户应对自己编写的代码负责。
+- 针对情况 2 和 4 的一个建议是，用户应首先检查错误是否在自实现代码中或原始代码中。例如，用户可以首先确保相同的模型在支持的数据集上运行良好。如果您仍然需要帮助，请描述您所做的工作和遇到的问题，并按照以下部分的步骤尽可能清晰地描述，以便我们更好地帮助您。
+
+**检查清单**
+
+1. 我已搜索相关问题，但无法获得预期的帮助。
+2. 最新版本中尚未修复此问题。

+# IndexKits  
+  
+[TOC]  
+  
+## Introduction  
+  
+Index Kits (`index_kits`) for streaming Arrow data.  
+  
+* Supports creating datasets from configuration files.  
+* Supports creating index v2 from arrows.  
+* Supports the creation, reading, and usage of index files.  
+* Supports the creation, reading, and usage of multi-bucket, multi-resolution indexes.  
+  
+`index_kits` has the following advantages:  
+  
+* Optimizes memory usage for streaming reads, supporting the reading of data at the billion level.  
+* Optimizes memory usage and reading speed of Index files.  
+* Supports the creation of Base/Multireso Index V2 datasets, including data filtering, repeating, and deduplication during creation.  
+* Supports loading various dataset types (Arrow files, Base Index V2, multiple Base Index V2, Multireso Index V2, multiple Multireso Index V2).  
+* Uses a unified API interface to access images, text, and other attributes for all dataset types.  
+* Built-in shuffle, `resize_and_crop`, and returns the coordinates of the crop.  
+  
+## Installation  
+  
+* **Install from pre-compiled whl (recommended)**  
+  
+* Install from source  
+  
+  ```shell  
+  cd IndexKits  
+  pip install -e .  
+  ```
+
+## Usage
+
+### Loading an Index V2 File
+
+```python
+from index_kits import ArrowIndexV2  
+  
+index_manager = ArrowIndexV2('data.json')  
+  
+# You can shuffle the dataset using a seed. If a seed is provided (i.e., the seed is not None), this shuffle will not affect any random state.  
+index_manager.shuffle(1234, fast=True)  
+  
+for i in range(len(index_manager)):  
+    # Get an image (requires the arrow to contain an image/binary column):  
+    pil_image = index_manager.get_image(i)  
+    # Get text (requires the arrow to contain a text_zh column):  
+    text = index_manager.get_attribute(i, column='text_zh')  
+    # Get MD5 (requires the arrow to contain an md5 column):  
+    md5 = index_manager.get_md5(i)  
+    # Get any attribute by specifying the column (must be contained in the arrow):  
+    ocr_num = index_manager.get_attribute(i, column='ocr_num')  
+    # Get multiple attributes at once  
+    item = index_manager.get_data(i, columns=['text_zh', 'md5'])     # i: in-dataset index  
+    print(item)  
+    # {  
+    #      'index': 3,              # in-json index  
+    #      'in_arrow_index': 3,     # in-arrow index  
+    #      'arrow_name': '/HunYuanDiT/dataset/porcelain/00000.arrow',   
+    #      'text_zh': 'Fortune arrives with the auspicious green porcelain tea cup',   
+    #      'md5': '1db68f8c0d4e95f97009d65fdf7b441c'  
+    # }  
+```
+
+
+### Loading a Set of Arrow Files
+
+If you have a small batch of arrow files, you can directly use `IndexV2Builder` to load these arrow files without creating an Index V2 file.
+
+```python
+from index_kits import IndexV2Builder  
+
+index_manager = IndexV2Builder(arrow_files).to_index_v2()  
+```
+
+### Loading a Multi-Bucket (Multi-Resolution) Index V2 File
+
+When using a multi-bucket (multi-resolution) index file, refer to the following example code, especially the definition of SimpleDataset and the usage of MultiResolutionBucketIndexV2.
+
+```python
+from torch.utils.data import DataLoader, Dataset  
+import torchvision.transforms as T  
+  
+from index_kits import MultiResolutionBucketIndexV2  
+from index_kits.sampler import BlockDistributedSampler  
+  
+class SimpleDataset(Dataset):  
+    def __init__(self, index_file, batch_size, world_size):  
+        # When using multi-bucket (multi-resolution), batch_size and world_size need to be specified for underlying data alignment.  
+        self.index_manager = MultiResolutionBucketIndexV2(index_file, batch_size, world_size)  
+  
+        self.flip_norm = T.Compose(  
+            [  
+                T.RandomHorizontalFlip(),  
+                T.ToTensor(),  
+                T.Normalize([0.5], [0.5]),  
+            ]  
+        )  
+  
+    def shuffle(self, seed, fast=False):  
+        self.index_manager.shuffle(seed, fast=fast)  
+  
+    def __len__(self):  
+        return len(self.index_manager)  
+  
+    def __getitem__(self, idx):  
+        image = self.index_manager.get_image(idx)  
+        original_size = image.size    # (w, h)  
+        target_size = self.index_manager.get_target_size(idx)     # (w, h)  
+        image, crops_coords_left_top = self.index_manager.resize_and_crop(image, target_size)  
+        image = self.flip_norm(image)  
+        text = self.index_manager.get_attribute(idx, column='text_zh')  
+        return image, text, (original_size, target_size, crops_coords_left_top)  
+  
+batch_size = 8      # batch_size per GPU  
+world_size = 8      # total number of GPUs  
+rank = 0            # rank of the current process  
+num_workers = 4     # customizable based on actual conditions  
+shuffle = False     # must be set to False  
+drop_last = True    # must be set to True  
+  
+# Correct batch_size and world_size must be passed in, otherwise, the multi-resolution data cannot be aligned correctly.   
+dataset = SimpleDataset('data_multireso.json', batch_size=batch_size, world_size=world_size)  
+# Must use BlockDistributedSampler to ensure the samples in a batch have the same resolution.  
+sampler = BlockDistributedSampler(dataset, num_replicas=world_size, rank=rank,  
+                                  shuffle=shuffle, drop_last=drop_last, batch_size=batch_size)  
+loader = DataLoader(dataset, batch_size=batch_size, shuffle=shuffle, sampler=sampler,  
+                    num_workers=num_workers, pin_memory=True, drop_last=drop_last)  
+  
+for epoch in range(10):  
+   # Please use the shuffle method provided by the dataset, not the DataLoader's shuffle parameter.  
+   dataset.shuffle(epoch, fast=True)  
+   for batch in loader:  
+       pass  
+```
+
+
+## Fast Shuffle
+
+When your index v2 file contains hundreds of millions of samples, using the default shuffle can be quite slow. Therefore, it’s recommended to enable `fast=True` mode:
+
+```python
+index_manager.shuffle(seed=1234, fast=True)
+```
+
+This will globally shuffle without keeping the indices of the same arrow together. Although this may reduce reading speed, it requires a trade-off based on the model’s forward time.

+
+[TOC]
+
+## Introdution
+
+The IndexKits library offers a command-line tool `idk` for creating datasets and viewing their statistical information. You can view the instructions by using `idk -h`. Here, it refers to creating an Index V2 format dataset from a series of arrow files.
+
+## 1. Creating a Base Index V2 Dataset
+
+### 1.1 Create a Base Index V2 dataset using `idk`
+
+When creating a Base Index V2 dataset, you need to specify the path to a configuration file using the `-c` parameter and a save path using the `-t` parameter.
+
+```shell
+idk base -c base_config.yaml -t base_dataset.json
+```
+
+### 1.2 Basic Configuration
+
+Next, let’s discuss how to write the configuration file. The configuration file is in `yaml` format, and below is a basic example:
+
+Filename: `base_config.yaml`
+
+```yaml
+source:
+    - /HunYuanDiT/dataset/porcelain/arrows/00000.arrow
+```
+
+|    Field Name    | Type  |     Description     |
+|:---------:|:---:|:----------:|
+|  source   | Optional  |  Arrow List  |
+
+
+We provide an example that includes all features and fields in [full_config.yaml](./docs/full_config.yaml).
+
+### 1.3 Filtering Criteria
+
+`idk` offers two types of filtering capabilities during the dataset creation process: (1) based on columns in Arrow, and (2) based on MD5 files. 
+
+To enable filtering criteria, add the `filter` field in the configuration file.
+
+#### 1.3.1 Column Filtering
+
+To enable column filtering, add the `column` field under the `filter` section. 
+Multiple column filtering criteria can be applied simultaneously, with the intersection of multiple conditions being taken.
+
+For example, to select data where both the length and width are greater than or equal to 512, 
+with the default being 1024 if the length and width are invalid:
+
+```yaml
+filter:
+    column:
+        -   name: height
+            type: int
+            action: ge
+            target: 512
+            default: 1024
+        -   name: width
+            type: int
+            action: ge
+            target: 512
+            default: 1024
+```
+
+This filtering condition is equivalent to `table['height'].to_int(default=1024) >= 512 && table['width'].to_int(default=1024) >= 512`.
+
+Each filtering criterion includes the following fields:
+
+|      Field Name    | Type  |   Description     |          Value Range          |
+|:------------------:|:---:|:---------------:|:----------------------:|
+|        name        | Required  |   Column name in Arrow    |       Column in Arrow       |
+|        type        | Required  |    Type of Elements in the Column     | `int`, `float` or `str` |
+|       action       | Required  |     Filtering Criteria     |    See the table below for possible values      |
+|       target       | Required  |    Filtering Criteria    |       Numeric or String       |
+|      default       | Required  | Default value when the element is invalid  |       Numeric or String       |
+| arrow_file_keyword | Optional  | Keywords in the Arrow file path |           -            |
+
+Below are the specific meanings of “action” and the optional values under different circumstances::
+
+|    Action     |                     Description                      |         Type          |    Action    |                 Description                  |         Type          |
+|:-------------:|:----------------------------------------------------:|:---------------------:|:------------:|:--------------------------------------------:|:---------------------:|
+|      eq       |                     equal, `==`                      | `int`, `float`, `str` |      ne      |               not equal, `!=`                | `int`, `float`, `str` |
+|      gt       |                   great than, `>`                    |    `int`, `float`     |      lt      |                less than, `<`                |    `int`, `float`     |
+|      ge       |                 great or equal, `>=`                 |    `int`, `float`     |      le      |             less or equal, `<=`              |    `int`, `float`     |
+|    len_eq     |           str length equal, `str.len()==`            |         `str`         |    len_ne    |     str length not equal, `str.len()!=`      |         `str`         |
+|    len_gt     |         str length great than, `str.len()>`          |         `str`         |    len_lt    |      str length less than, `str.len()<`      |         `str`         |
+|    len_ge     |       str length great or equal, `str.len()>=`       |         `str`         |    len_le    |   str length less or equal, `str.len()<=`    |         `str`         |
+|   contains    |         str contains, `str.contains(target)`         |         `str`         | not_contains | str not contains, `str.not_contains(target)` |         `str`         |
+|      in       |              str in,  `str.in(target)`               |         `str`         |    not_in    |       str not in, `str.not_in(target)`       |         `str`         |
+| lower_last_in | lower str last char in, `str.lower()[-1].in(target)` |         `str`         |              |                                              |                       |
+
+#### 1.3.2 MD5 Filtering
+
+Add an `md5` field under the `filter` section to initiate MD5 filtering. Multiple MD5 filtering criteria can be applied simultaneously, with the intersection of multiple conditions being taken. 
+
+例如:
+* `badcase.txt` is a list of MD5s, aiming to filter out the entries listed in these lists.
+* `badcase.json` is a dictionary, where the key is the MD5 and the value is a text-related `tag`. The goal is to filter out specific `tags`.
+
+```shell
+filter:
+    md5:
+        - name: badcase1
+          path:
+            - badcase1.txt
+          type: list
+          action: in
+          is_valid: false
+        - name: badcase2
+          path: badcase2.json
+          type: dict
+          action: eq
+          target: 'Specified tag'
+          is_valid: false
+```
+
+Each filtering criterion includes five fields:
+
+|        Field Name         | Type  |                                Description                                |                                        Value Range                                        |
+|:------------------:|:---:|:-----------------------------------------------------------------:|:------------------------------------------------------------------------------------:|
+|        name        | Required  |     The name of the filtering criterion, which can be customized for ease of statistics.                       |                                          -                                           |
+|        path        | Required  | The path to the filtering file, which can be a single path or multiple paths provided in a list format. Supports `.txt`, `.json`, `.pkl` formats. |                                          -                                           |
+|        type        | Required  |                         The type of records in the filtering file.                       |                                   `list` or `dict`                               | 
+|       action       | Required  |                           The filtering action.                             | For `list`: `in`, `not_in`; For `dict`: `eq`, `ne`, `gt`, `lt`, `ge`, `le`|
+|       target       | Optional  |                         The filtering criterion.                              |                               Required when type is `dict`                               |
+|      is_valid      | Required  |                 Whether a hit on action+target is considered valid or invalid.                  |                                  `true` or `false`                           |
+| arrow_file_keyword | Optional  |                       Keywords in the Arrow file path.                       |                                          -                                           |
+
+### 1.4 Advanced Filtering
+
+`idk` also supports some more advanced filtering functions.
+
+#### 1.4.1  Filtering Criteria Applied to Part of Arrow Files
+
+Using the `arrow_file_keyword` parameter, filtering criteria can be applied only to part of the Arrow files. 
+
+For example:
+
+* The filtering criterion `height>=0` applies only to arrows whose path includes `human`.
+* The filtering criterion “keep samples in goodcase.txt” applies only to arrows whose path includes `human`.
+
+```yaml
+filter:
+    column:
+        - name: height
+          type: int
+          action: ge
+          target: 512
+          default: 1024
+          arrow_file_keyword:
+              - human
+
+    md5:
+        - name: goodcase
+          path: goodcase.txt
+          type: list
+          action: in
+          is_valid: true
+          arrow_file_keyword:
+            - human
+```
+
+#### 1.4.2 The “or” Logic in Filtering Criteria
+
+By default, filtering criteria follow an “and” logic. If you want two or more filtering criteria to follow an “or” logic, you should use the `logical_or` field. The column filtering criteria listed under this field will be combined using an “or” logic.
+
+```yaml
+filter:  
+    column:  
+        - logical_or:  
+            -   name: md5  
+                type: str  
+                action: lower_last_in  
+                target: '02468ace'  
+                default: ''  
+            -   name: text_zh  
+                type: str  
+                action: contains  
+                target: 'turtle|rabbit|duck|swan|peacock|hedgehog|wolf|fox|seal|crow|deer'  
+                default: ''
+```
+
+Special Note: The `logical_or` field is applicable only to the `column` filtering criteria within `filter`.
+
+1.4.3 Excluding Certain Arrows from the Source
+
+While wildcards can be used to fetch multiple arrows at once, there might be instances where we want to exclude some of them. This can be achieved through the `exclude` field. Keywords listed under `exclude`, if found in the path of the current group of arrows, will result in those arrows being excluded.
+
+```yaml
+source:
+    - /HunYuanDiT/dataset/porcelain/arrows/*.arrow:
+        exclude:
+            - arrow1
+            - arrow2
+```
+
+### 1.5 Repeating Samples  
+  
+`idk` offers the capability to repeat either all samples or specific samples during dataset creation. There are three types of repeaters:  
+* Directly repeating the source  
+* Based on keywords in the Arrow file name (enable repeat conditions by adding the `repeater` field in the configuration file)  
+* Based on an MD5 file (enable repeat conditions by adding the `repeater` field in the configuration file)  
+  
+**Special Note:** The above three conditions can be used simultaneously. If a sample meets multiple repeat conditions, the highest number of repeats will be taken.  
+  
+#### 1.5.1 Repeating the Source  
+  
+In the source, for the Arrow(s) you want to repeat (which can include wildcards like `*`, `?`), add `repeat: n` to mark the number of times to repeat.  
+  
+```yaml  
+source:  
+    - /HunYuanDiT/dataset/porcelain/arrows/*.arrow:  
+        repeat: 10  
+```
+
+**Special Note: Add a colon at the end of the Arrow path**
+
+#### 1.5.2 Arrow Keywords
+
+Add an `arrow_file_keyword` field under the `repeater` section.
+
+```yaml
+repeater:  
+    arrow_file_keyword:  
+        - repeat: 8  
+          keyword:  
+            - Lolita anime style  
+            - Minimalist style  
+        - repeat: 5  
+          keyword:  
+              - Magical Barbie style  
+              - Disney style  
+```
+
+Each repeat condition includes two fields:
+
+
+|   Field Name	   | Type  |       Description        | Value Range |
+|:-------:|:---:|:---------------:|:----:|
+| repeat  | Required  |  The number of times to repeat  |  Number  |
+| keyword | Required  | Keywords in the Arrow file path |  -    |
+
+
+#### 1.5.3 MD5 File
+
+Add an `md5` field under the `repeater` section.
+
+```yaml
+repeater:
+    md5:
+        - name: goodcase1
+          path: /HunYuanDiT/dataset/porcelain/md5_repeat_1.json
+          type: dict
+          plus: 3
+        - name: goodcase2
+          path: /HunYuanDiT/dataset/porcelain/md5_repeat_2.json
+          type: list
+          repeat: 6
+```
+
+Each repeat condition includes the following fields:
+
+
+|  Field Name   | Type  |                       Description	                     |            Value Range               |
+|:------:|:---:|:----------------------------------------------:|:---------------------------:|
+|  name  | Required  |               Custom name for the repeat condition                |              -              |
+|  path  | Required  |                 Path to the file containing MD5s               | `.txt`, `.json`, or `.pkl` formats |
+|  type  | Required  |                  Type of the MD5 file                 |       `list` or `dict`       |
+| repeat | Optional  |     Number of times to repeat, this will override plus     |             Integer              |
+|  plus  | Optional  | Adds this value to the value obtained from the MD5 file as the number of repeats |             Integer              |
+
+### 1.6 Deduplication
+
+To deduplicate, add `remove_md5_dup` and set it to `true`. For example:
+
+```yaml
+remove_md5_dup: true
+```
+
+**Special Note:** Deduplication is performed after repeat conditions, so using them together will make repeat ineffective.
+
+### 1.7 Creating a Base Index V2 Dataset with Python Code
+
+```python
+from index_kits import IndexV2Builder
+
+builder = IndexV2Builder(arrow_files)
+builder.save('data_v2.json')
+```
+

+## 2. Creating a Multireso Index V2 Dataset
+
+### 2.1 Creating a Multireso Index V2 Dataset with `idk`
+To create a multi-resolution dataset, you can do so through a configuration file:
+
+```shell
+src:
+    - /HunYuanDiT/dataset/porcelain/jsons/a.json
+    - /HunYuanDiT/dataset/porcelain/jsons/b.json
+    - /HunYuanDiT/dataset/porcelain/jsons/c.json
+base_size: 512
+reso_step: 32
+min_size: 512
+```
+
+The fields are as follows:
+
+|      Field Name      | Type  |                           Description                           |              Value Range               |
+|:-------------:|:---:|:------------------------------------------------------:|:-------------------------------:|
+|      src      | Required  |       Path(s) to the Base Index V2 file, can be single or multiple           |                -                |
+|   base_size   | Required  |              The base resolution (n, n) from which to create multiple resolutions               |        Recommended values: 256/512/1024      |
+|   reso_step   | Optional  | The step size for traversing multiple resolutions. Choose either this or target_ratios	 |          Recommended values: 16/32/64         |
+| target_ratios | Optional  | Target aspect ratios, a list. Choose either this or reso_step	 | Recommended values: 1:1, 4:3, 3:4, 16:9, 9:16  |
+|     align     | Optional  | When using target_ratios, the multiple to align the target resolution to	 | Recommended value: 16 (2x patchify, 8x VAE) |
+|   min_size    | Optional  | The minimum resolution filter for samples when creating from Base to Multireso Index V2	 |       Recommended values: 256/512/1024      |
+|   md5_file    | Optional  | A pre-calculated dictionary of image sizes in pkl format, key is MD5, value is (h, w)	 |                -                |
+
+
+### 2.2 Creating a Multireso Index V2 Dataset with Python Code
+
+First, import the necessary function
+
+```python
+from index_kits import build_multi_resolution_bucket  
+  
+md5_hw = None  
+# If many arrows in your Index V2 lack height and width, you can pre-calculate them and pass through the md5_hw parameter.  
+# md5_hw = {'c67be1d8f30fd0edcff6ac99b703879f': (720, 1280), ...}  
+# with open('md5_hw.pkl', 'rb') as f:  
+#     md5_hw = pickle.load(f)  
+  
+index_v2_file_path = 'data_v2.json'  
+index_v2_save_path = 'data_multireso.json'  
+  
+# Method 1: Given base_size and reso_step, automatically calculate all resolution buckets.  
+build_multi_resolution_bucket(base_size=1024,  
+                              reso_step=64,

+                              md5_hw=md5_hw)  
+  
+# Method 2: Given a series of target aspect ratios, automatically calculate all resolution buckets.  
+build_multi_resolution_bucket(base_size=1024,  
+                              target_ratios=["1:1", "3:4", "4:3", "16:9", "9:16"],  
+                              align=16,  
+                              min_size=1024,  
+                              src_index_files=index_v2_file_path,

+                              md5_hw=md5_hw)  
+```
+
+**Note：** If both reso_step and target_ratios are provided, target_ratios will be prioritized.
