+## Contributing to InternLM
+
+Welcome to the InternLM community, all kinds of contributions are welcomed, including but not limited to
+
+**Fix bug**
+
+You can directly post a Pull Request to fix typo in code or documents
+
+The steps to fix the bug of code implementation are as follows.
+
+1. If the modification involve significant changes, you should create an issue first and describe the error information and how to trigger the bug. Other developers will discuss with you and propose an proper solution.
+
+2. Posting a pull request after fixing the bug and adding corresponding unit test.
+
+**New Feature or Enhancement**
+
+1. If the modification involve significant changes, you should create an issue to discuss with our developers to propose an proper design.
+2. Post a Pull Request after implementing the new feature or enhancement and add corresponding unit test.
+
+**Document**
+
+You can directly post a pull request to fix documents. If you want to add a document, you should first create an issue to check if it is reasonable.
+
+### Pull Request Workflow
+
+If you're not familiar with Pull Request, don't worry! The following guidance will tell you how to create a Pull Request step by step. If you want to dive into the develop mode of Pull Request, you can refer to the [official documents](https://docs.github.com/en/github/collaborating-with-issues-and-pull-requests/about-pull-requests)
+
+#### 1. Fork and clone
+
+If you are posting a pull request for the first time, you should fork the OpenMMLab repositories by clicking the **Fork** button in the top right corner of the GitHub page, and the forked repositories will appear under your GitHub profile.
+
+<img src="https://user-images.githubusercontent.com/57566630/167305749-43c7f4e9-449b-4e98-ade5-0c9276d5c9ce.png" width="1200">
+
+Then, you can clone the repositories to local:
+
+```shell
+git clone git@github.com:{username}/lmdeploy.git
+```
+
+After that, you should add official repository as the upstream repository
+
+```bash
+git remote add upstream git@github.com:InternLM/lmdeploy.git
+```
+
+Check whether remote repository has been added successfully by `git remote -v`
+
+```bash
+origin	git@github.com:{username}/lmdeploy.git (fetch)
+origin	git@github.com:{username}/lmdeploy.git (push)
+upstream	git@github.com:InternLM/lmdeploy.git (fetch)
+upstream	git@github.com:InternLM/lmdeploy.git (push)
+```
+
+> Here's a brief introduction to origin and upstream. When we use "git clone", we create an "origin" remote by default, which points to the repository cloned from. As for "upstream", we add it ourselves to point to the target repository. Of course, if you don't like the name "upstream", you could name it as you wish. Usually, we'll push the code to "origin". If the pushed code conflicts with the latest code in official("upstream"), we should pull the latest code from upstream to resolve the conflicts, and then push to "origin" again. The posted Pull Request will be updated automatically.
+
+#### 2. Configure pre-commit
+
+You should configure [pre-commit](https://pre-commit.com/#intro) in the local development environment to make sure the code style matches that of InternLM. **Note**: The following code should be executed under the lmdeploy directory.
+
+```shell
+pip install -U pre-commit
+pre-commit install
+```
+
+Check that pre-commit is configured successfully, and install the hooks defined in `.pre-commit-config.yaml`.
+
+```shell
+pre-commit run --all-files
+```
+
+<img src="https://user-images.githubusercontent.com/57566630/173660750-3df20a63-cb66-4d33-a986-1f643f1d8aaf.png" width="1200">
+
+<img src="https://user-images.githubusercontent.com/57566630/202368856-0465a90d-8fce-4345-918e-67b8b9c82614.png" width="1200">
+
+If the installation process is interrupted, you can repeatedly run `pre-commit run ... ` to continue the installation.
+
+If the code does not conform to the code style specification, pre-commit will raise a warning and  fixes some of the errors automatically.
+
+<img src="https://user-images.githubusercontent.com/57566630/202369176-67642454-0025-4023-a095-263529107aa3.png" width="1200">
+
+If we want to commit our code bypassing the pre-commit hook, we can use the `--no-verify` option(**only for temporarily commit**).
+
+```shell
+git commit -m "xxx" --no-verify
+```
+
+#### 3. Create a development branch
+
+After configuring the pre-commit, we should create a branch based on the master branch to develop the new feature or fix the bug. The proposed branch name is `username/pr_name`
+
+```shell
+git checkout -b yhc/refactor_contributing_doc
+```
+
+In subsequent development, if the master branch of the local repository is behind the master branch of "upstream", we need to pull the upstream for synchronization, and then execute the above command:
+
+```shell
+git pull upstream master
+```
+
+#### 4. Commit the code and pass the unit test
+
+- lmdeploy introduces mypy to do static type checking to increase the robustness of the code. Therefore, we need to add Type Hints to our code and pass the mypy check. If you are not familiar with Type Hints, you can refer to [this tutorial](https://docs.python.org/3/library/typing.html).
+
+- The committed code should pass through the unit test
+
+  ```shell
+  # Pass all unit tests
+  pytest tests
+
+  # Pass the unit test of runner
+  pytest tests/test_runner/test_runner.py
+  ```
+
+  If the unit test fails for lack of dependencies, you can install the dependencies referring to the [guidance](#unit-test)
+
+- If the documents are modified/added, we should check the rendering result referring to [guidance](#document-rendering)
+
+#### 5. Push the code to remote
+
+We could push the local commits to remote after passing through the check of unit test and pre-commit. You can associate the local branch with remote branch by adding `-u` option.
+
+```shell
+git push -u origin {branch_name}
+```
+
+This will allow you to use the `git push` command to push code directly next time, without having to specify a branch or the remote repository.
+
+#### 6. Create a Pull Request
+
+(1) Create a pull request in GitHub's Pull request interface
+
+<img src="https://user-images.githubusercontent.com/57566630/201533288-516f7ac4-0b14-4dc8-afbd-912475c368b5.png" width="1200">
+
+(2) Modify the PR description according to the guidelines so that other developers can better understand your changes
+
+<img src="https://user-images.githubusercontent.com/57566630/202242953-c91a18ff-e388-4ff9-8591-5fae0ead6c1e.png" width="1200">
+
+Find more details about Pull Request description in [pull request guidelines](#pr-specs).
+
+**note**
+
+(a) The Pull Request description should contain the reason for the change, the content of the change, and the impact of the change, and be associated with the relevant Issue (see [documentation](https://docs.github.com/en/issues/tracking-your-work-with-issues/linking-a-pull-request-to-an-issue))
+
+(b) If it is your first contribution, please sign the CLA
+
+<img src="https://user-images.githubusercontent.com/57566630/167307569-a794b967-6e28-4eac-a942-00deb657815f.png" width="1200">
+
+(c) Check whether the Pull Request pass through the CI
+
+<img src="https://user-images.githubusercontent.com/57566630/167307490-f9ebf9fa-63c0-4d83-8ba1-081ea169eb3a.png" width="1200">
+
+IternLM will run unit test for the posted Pull Request on different platforms (Linux, Window, Mac), based on different versions of Python, PyTorch, CUDA to make sure the code is correct. We can see the specific test information by clicking `Details` in the above image so that we can modify the code.
+
+(3) If the Pull Request passes the CI, then you can wait for the review from other developers. You'll modify the code based on the reviewer's comments, and repeat the steps [4](#4-commit-the-code-and-pass-the-unit-test)-[5](#5-push-the-code-to-remote) until all reviewers approve it. Then, we will merge it ASAP.
+
+<img src="https://user-images.githubusercontent.com/57566630/202145400-cc2cd8c4-10b0-472f-ba37-07e6f50acc67.png" width="1200">
+
+#### 7. Resolve conflicts
+
+If your local branch conflicts with the latest master branch of "upstream", you'll need to resolove them. There are two ways to do this:
+
+```shell
+git fetch --all --prune
+git rebase upstream/master
+```
+
+or
+
+```shell
+git fetch --all --prune
+git merge upstream/master
+```
+
+If you are very good at handling conflicts, then you can use rebase to resolve conflicts, as this will keep your commit logs tidy. If you are not familiar with `rebase`, then you can use `merge` to resolve conflicts.
+
+### Guidance
+
+#### Document rendering
+
+If the documents are modified/added, we should check the rendering result. We could install the dependencies and run the following command to render the documents and check the results:
+
+```shell
+pip install -r requirements/docs.txt
+cd docs/zh_cn/
+# or docs/en
+make html
+# check file in ./docs/zh_cn/_build/html/index.html
+```
+
+### Code style
+
+#### Python
+
+We adopt [PEP8](https://www.python.org/dev/peps/pep-0008/) as the preferred code style.
+
+We use the following tools for linting and formatting:
+
+- [flake8](https://github.com/PyCQA/flake8): A wrapper around some linter tools.
+- [isort](https://github.com/timothycrosley/isort): A Python utility to sort imports.
+- [yapf](https://github.com/google/yapf): A formatter for Python files.
+- [codespell](https://github.com/codespell-project/codespell): A Python utility to fix common misspellings in text files.
+- [mdformat](https://github.com/executablebooks/mdformat): Mdformat is an opinionated Markdown formatter that can be used to enforce a consistent style in Markdown files.
+- [docformatter](https://github.com/myint/docformatter): A formatter to format docstring.
+
+We use [pre-commit hook](https://pre-commit.com/) that checks and formats for `flake8`, `yapf`, `isort`, `trailing whitespaces`, `markdown files`,
+fixes `end-of-files`, `double-quoted-strings`, `python-encoding-pragma`, `mixed-line-ending`, sorts `requirments.txt` automatically on every commit.
+The config for a pre-commit hook is stored in [.pre-commit-config](../.pre-commit-config.yaml).
+
+#### C++ and CUDA
+
+The clang-format config is stored in [.clang-format](../.clang-format). And it's recommended to use clang-format version **11**. Please do not use older or newer versions as they will result in differences after formatting, which can cause the [lint](https://github.com/InternLM/lmdeploy/blob/main/.github/workflows/lint.yml#L25) to fail.
+
+### PR Specs
+
+1. Use [pre-commit](https://pre-commit.com) hook to avoid issues of code style
+
+2. One short-time branch should be matched with only one PR
+
+3. Accomplish a detailed change in one PR. Avoid large PR
+
+   - Bad: Support Faster R-CNN
+   - Acceptable: Add a box head to Faster R-CNN
+   - Good: Add a parameter to box head to support custom conv-layer number
+
+4. Provide clear and significant commit message
+
+5. Provide clear and meaningful PR description
+
+   - Task name should be clarified in title. The general format is: \[Prefix\] Short description of the PR (Suffix)
+   - Prefix: add new feature \[Feature\], fix bug \[Fix\], related to documents \[Docs\], in developing \[WIP\] (which will not be reviewed temporarily)
+   - Introduce main changes, results and influences on other modules in short description
+   - Associate related issues and pull requests with a milestone

INSTALLATION.md

+## 🛠️ Installation
+
+- Clone this repository:
+
+  ```bash
+  git clone https://github.com/OpenGVLab/InternVL.git
+  ```
+
+- Create a conda virtual environment and activate it:
+
+  ```bash
+  conda create -n internvl python=3.9 -y
+  conda activate internvl
+  ```
+
+- Install dependencies using `requirements.txt`:
+
+  ```bash
+  pip install -r requirements.txt
+  ```
+  
+  By default, our `requirements.txt` file includes the following dependencies:
+  
+  - `-r requirements/internvl_chat.txt`
+  - `-r requirements/streamlit_demo.txt`
+  - `-r requirements/classification.txt`
+  - `-r requirements/segmentation.txt`
+  
+  The `clip_benchmark.txt` is **not** included in the default installation. If you require the `clip_benchmark` functionality, please install it manually by running the following command:
+
+  ```bash
+  pip install -r requirements/clip_benchmark.txt
+  ```
+
+### Additional Instructions
+
+- Install `flash-attn==2.3.6`:
+
+  ```bash
+  pip install flash-attn==2.3.6 --no-build-isolation
+  ```
+
+  Alternatively you can compile from source:
+
+  ```bash
+  git clone https://github.com/Dao-AILab/flash-attention.git
+  cd flash-attention
+  git checkout v2.3.6
+  python setup.py install
+  ```
+
+- Install `mmcv-full==1.6.2` (optional, for `segmentation`):
+
+  ```bash
+  pip install -U openmim
+  mim install mmcv-full==1.6.2
+  ```
+
+- Install `apex` (optional, for `segmentation`):
+
+  ```bash
+  git clone https://github.com/NVIDIA/apex.git
+  git checkout 2386a912164b0c5cfcd8be7a2b890fbac5607c82  # https://github.com/NVIDIA/apex/issues/1735
+  pip install -v --disable-pip-version-check --no-cache-dir --no-build-isolation --config-settings "--build-option=--cpp_ext" --config-settings "--build-option=--cuda_ext" ./
+  ```
+
+  If you encounter `ModuleNotFoundError: No module named 'fused_layer_norm_cuda'`, it is because apex's CUDA extensions are not being installed successfully. You can try uninstalling apex and the code will default to the PyTorch version of RMSNorm. Alternatively, if you prefer using apex, try adding a few lines to `setup.py` and then recompiling.

+## 模型结构
+
+InternVL 2.0的架构集成了一个预训练的视觉变换器模型（InternViT-6B）和一个预训练的语言模型（InternLM2-20B）。这两个模型通过一个随机初始化的多层感知器（MLP）投影器连接起来。InternViT-6B是一个视觉基础模型（VFM），它在预训练阶段通过持续学习策略进行改进，增强了模型对视觉内容的理解能力，并提高了其在不同语言模型中的适应性。InternLM2-20B作为语言基础模型，提供了强大的初始语言处理能力。在训练过程中，MLP投影器用于优化视觉特征提取，将视觉编码器的输出与语言模型的输入相匹配。

+
+## 算法原理
+
+InternVL2.0采用了一种动态的高分辨率训练方法，该方法将图像分割成448×448像素的瓦片，瓦片数量根据输入图像的纵横比和分辨率在1到12之间变化。在测试阶段，这个数量可以扩展到40个瓦片（即4K分辨率）。为了增强高分辨率下的可扩展性，模型使用了一个简单的像素洗牌操作，将视觉标记的数量减少到原始数量的四分之一。因此，在模型中，一个448×448像素的图像由256个视觉标记表示。在微调阶段，模型使用了精心选择的数据集来增强在多模态任务中的性能，这些数据集包括图像字幕、通用问答、科学图像理解、图表解释、数学问题解决、基于知识的问答、OCR和文档理解等。

+# InternViT-6B for Image Classification
+
+This folder contains the implementation of the InternViT-6B for image classification, which corresponds to Section 4.2.1 of our [InternVL 1.0 paper](https://arxiv.org/pdf/2312.14238).
+The codebase for this part is derived from [InternImage](https://github.com/OpenGVLab/InternImage), with some code references to [EVA](https://github.com/baaivision/EVA/tree/master) and [DINOv2](https://github.com/facebookresearch/dinov2). Thanks for their great work.
+
+In this part, we validate the visual perception capabilities of InternViT-6B, the most core component of InternVL 1.0.
+We evaluate the quality of visual representation produced by InternViT-6B using the ImageNet-1K dataset. Following common practices, we adopt the linear probing evaluation, i.e. training a linear classifier while keeping the backbone frozen. In addition to the ImageNet-1K validation set,
+we also report performance metrics on several ImageNet variants, to benchmark the domain generalization capability.
+
+InternViT-6B follows the structure of vanilla ViT, and its hyperparameters are listed in the table below.
