+
+## 模型结构
+LLaMA，这是一个基础语言模型的集合，参数范围从7B到65B。在数万亿的tokens上训练出的模型，并表明可以专门使用公开可用的数据集来训练最先进的模型，而不依赖于专有的和不可访问的数据集。特别是，llama 13B在大多数基准测试中优于GPT-3 (175B)， LLaMA 65B与最好的模型Chinchilla-70B和PaLM-540B具有竞争力。LLAMA网络基于 Transformer 架构。提出了各种改进，并用于不同的模型，例如 PaLM。
+LLaMA2相较于LLaMA采用了更强大的数据清洗、更多的tokens训练、加倍的上下文长度，并支持了Grouped-query attention （GQA），即允许在多头注意力（MHA）模型中共享键和值投影，从而减少与缓存相关的内存成本的优化方法。通过使用 GQA，更大的模型可以在优化内存使用的同时保持性能。

+
+
+## 算法原理
+以下是与原始 Transformer 架构的主要区别：
+
+**预归一化**。为了提高训练稳定性，对每个transformer 子层的输入进行归一化，而不是对输出进行归一化。使用 RMSNorm 归一化函数。
+
+**SwiGLU 激活函数 [PaLM]**。使用 SwiGLU 激活函数替换 ReLU 非线性以提高性能。使用 2 /3 4d 的维度而不是 PaLM 中的 4d。
+
+**旋转嵌入**。移除了绝对位置嵌入，而是添加了旋转位置嵌入 (RoPE)，在网络的每一层。

+# Distributed Optimizer
+
+The motivation for the distributed optimizer is to save memory by distributing the optimizer state evenly across data parallel ranks, versus the current method of replicating the optimizer state across data parallel ranks. As described in https://arxiv.org/abs/1910.02054, this branch specifically implements the following:
+
+- [yes] distribute all 'non-overlapping' optimizer state (i.e., model params already in fp32 are NOT distributed)
+- [no] distribute model gradients
+- [no] distribute model parameters
+
+Theoretical memory savings vary depending on the combination of the model's param dtype and grad dtype. In the current implementation, the theoretical number of bytes per parameter is (where 'd' is the data parallel size):
+
+|        | Non-distributed optim | Distributed optim |
+| ------ | ------ | ------ |
+| float16 param, float16 grads | 20 | 4 + 16/d |
+| float16 param, fp32 grads    | 18 | 6 + 12/d |
+| fp32 param, fp32 grads       | 16 | 8 + 8/d  |
+
+The implementation of the distributed optimizer is centered on using the contiguous grad buffer for communicating grads & params between the model state and the optimizer state. The grad buffer at any given moment either holds:
+
+1. all model grads
+2. a 1/d size _copy_ of the main grads (before copying to the optimizer state)
+3. a 1/d size _copy_ of the main params (after copying from the optimizer state)
+4. all model params
+5. zeros (or None), between iterations
+
+The grad buffer is used for performing reduce-scatter and all-gather operations, for passing grads & params between the model state and optimizer state. With this implementation, no dynamic buffers are allocated.
+
+The figures below illustrate the grad buffer's sharding scheme, and the key steps of the distributed optimizer's param update:

+## Data flow

+![Data flow](images/distrib_optimizer/data_flow.png)
+
+## Sharding scheme
+
+![Sharding scheme](images/distrib_optimizer/sharding_scheme.png)
+
+## Key steps
+
+_(note: using illustrations above, and assuming fp16 grads)_
+
+- Backward pass finishes (grad buffer holds 16 fp16 grad elements)
+- Call reduce-scatter on each DP rank
+- Each DP rank now has 4 elements within the grad buffer that are fully reduced (remaining 12 elements are garbage)
+- Each DP rank copies its relevant 4 fp16 grad elements from the grad buffer into 4 fp32 main grad elements (separate buffer, owned by the optimizer); i.e.
+  - DP rank 0 copies elements [0:4]
+  - DP rank 1 copies elements [4:8]
+  - DP rank 2 copies elements [8:12]
+  - DP rank 3 copies elements [12:16]
+- Optimizer.step()
+- Each DP rank copies its 4 fp32 main (/optimizer) param elements into the corresponding 4 fp16 elements in the grad buffer
+- Call all-gather on each DP rank
+- Grad buffer now contains all 16, fully updated, fp16 model param elements
+- Copy updated model params from grad buffer into their respective param tensors
+- (At this point, grad buffer is ready to be zero'd for the next iteration)

+}
+```
+
+## Usage
+
+### Prepare your environment
+
+The project environment is based on the standard [nvcr docker](nvcr.io/nvidia/pytorch:21.12-py3) of version `nvcr.io/nvidia/pytorch:21.12-py3`.
+
+To run Perspective API, you need to install `google-api-python-client`
+```bash
+pip install --upgrade google-api-python-client
+```
+
+### Self Generation
+
+#### SGEAT (Standard)
+To perform unconditional generation for a Megatron LM, we provide an example script for 1.3B LM.
+
+```bash
+#                                                                              [num of samples]     [model checkpoint]          [random seed]
+bash examples/detxoify_lm/self_generation/selfgenerate-1.3b-unconditional.sh       1000          checkpoints/gpt3/gpt3-1.3b/      2333
+```
+This will generate a jsonl file of  1000 generated text (as a toy example) at `selfgeneration/unconditional_generation_gpt3-1.3b/2333.out`. 
+
+Note that you may want to set your own gpt2 vocab and merge file dir, as well as your output data dir in `selfgenerate-1.3b-unconditional.sh`.
+
+### Annotation
+
+We then use Perspective API to annotate the self generated corpus. Note that you need to fill in your own Perspective API key in the `examples/detoxify_lm/perspective_api_annotate.py`. 
+
+```bash
+python examples/detxoify_lm/perspective_api_annotate.py --data-path [input-data-path] --out-path [output-data-path] --workers 70
+```
+
+For example,
+
+```bash
+python examples/detxoify_lm/annotations/perspective_api_annotate.py --data-path  selfgeneration/unconditional_generation_gpt3-1.3b/2333.out --out-path  selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.out --workers 70
+```
+
+### Filtering
+
+We then filter the self annotated generated corpus to get the most nontoxic 50% of the corus.
+
+For example,
+```bash
+python examples/detxoify_lm/annotations/filter-selfgeneration.py --data-path  selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.out --out-path  selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.nontoxic.out
+```
+
+This will generate a jsonl file of 500 text of the lowest toxicity (as a toy example) at `selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.nontoxic.out`. 
+
+
+### Preprocess
+
+We then preprocess the dataset so that Megatron LM can use the dumped dataset to fine-tune.
+
+```
+bash examples/detxoify_lm/annotations/preprocess.sh selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.nontoxic.out selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.nontoxic
+```
+
+This will generate two files as follows
+```bash
+selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.nontoxic_text_document.idx
+selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.nontoxic_text_document.bin
+```
+which will be used in the following domain-adative training step.
+
+### Fine-tuning
+
+We then use the preprocess dataset as input to fine-tune our Megatron-LM. 
+```bash
+#                                                                          [fine-tuning dataset]                                                                      [output-dir]                             [lr]    [bs]      [train-iters]                       [load checkpoint]
+bash examples/detxoify_lm/finetune_gpt_distributed-1.3b.sh    selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.nontoxic_text_document         gpt3-1.3b-toy-example-lr-2e-5-bs-512             2e-5     512            78                          checkpoints/gpt3/gpt3-1.3b
+```
+
+This will dump the final checkpoint in `$SHARE_DATA/gpt3-1.3b-toy-example-lr-2e-5-bs-512`. (`$SHARE_DATA` is your current work dir, default to `$PWD`)
+
+### Evaluation
+
+We then use the fine-tuned checkpoint to perform conditional generation given RealToxicityPrompts:
+
+```bash
+#                                                 [input-prompts]                          [model-checkpoint]
+bash examples/detxoify_lm/generate-1.3b.sh     augmented_prompts.jsonl      $SHARE_DATA/gpt3-1.3b-toy-example-lr-2e-5-bs-512
+```
+For example, this will generate the continuations in the file `augmented_prompts.jsonl_output_gpt3-1.3b-toy-example-lr-2e-5-bs-512_seed_31846.jsonl` (seed is a random generated number).
+
+Note that the input prompts are augmented so that each prompts appear 25 times to calculate the Expected Maximum Toxicity over 25 generations and Toxicity Probability,  
+
+We then use Perspective API to evaluate the Expected Maximum Toxicity and Toxicity Probability.   
+
+```bash
+python examples/detxoify_lm/perspective_api.py --data-path "augmented_prompts.jsonl_output_gpt3-1.3b-toy-example-lr-2e-5-bs-512_seed_31846.jsonl" --prompt-path prompts.jsonl --workers 30
+```
