# Benchmarks
## Benchmark OPT with LoRA on dummy prompt data
We provide various OPT models (string in parentheses is the corresponding model name used in this script):
- OPT-125M (125m)
- OPT-350M (350m)
- OPT-700M (700m)
- OPT-1.3B (1.3b)
- OPT-2.7B (2.7b)
- OPT-3.5B (3.5b)
- OPT-5.5B (5.5b)
- OPT-6.7B (6.7b)
- OPT-10B (10b)
- OPT-13B (13b)
We also provide various training strategies:
- ddp: torch DDP
- colossalai_gemini: ColossalAI GeminiDDP with `placement_policy="cuda"`, like zero3
- colossalai_gemini_cpu: ColossalAI GeminiDDP with `placement_policy="cpu"`, like zero3-offload
- colossalai_zero2: ColossalAI zero2
- colossalai_zero2_cpu: ColossalAI zero2-offload
- colossalai_zero1: ColossalAI zero1
- colossalai_zero1_cpu: ColossalAI zero1-offload
We only support `torchrun` to launch now. E.g.
```bash
# run OPT-125M with no lora (lora_rank=0) on single-node single-GPU with min batch size
torchrun --standalone --nproc_per_node 1 benchmark_opt_lora_dummy.py \
--model 125m --critic_model 125m --strategy ddp \
--experience_batch_size 1 --train_batch_size 1 --lora_rank 0
# run Actor (OPT-1.3B) and Critic (OPT-350M) with lora_rank=4 on single-node 4-GPU
torchrun --standalone --nproc_per_node 4 benchmark_opt_lora_dummy.py \
--model 1.3b --critic_model 350m --strategy colossalai_zero2 --lora_rank 4
```

logger = logging.get_logger(__name__)
class ChatGLMConfig(PretrainedConfig):
r"""
This is the configuration class to store the configuration of a [`~ChatGLMModel`].
It is used to instantiate an ChatGLM model according to the specified arguments, defining the model
architecture. Instantiating a configuration with the defaults will yield a similar configuration to that of
the ChatGLM-6B [THUDM/ChatGLM-6B](https://huggingface.co/THUDM/chatglm-6b) architecture.
Configuration objects inherit from [`PretrainedConfig`] and can be used
to control the model outputs. Read the documentation from [`PretrainedConfig`]
for more information.
Args:
vocab_size (`int`, *optional*, defaults to 150528):
Vocabulary size of the ChatGLM-6B model. Defines the number of different tokens that can be represented by the
`inputs_ids` passed when calling [`~ChatGLMModel`] or
[`~TFChatGLMModel`].
hidden_size (`int`, *optional*, defaults to 4096):
Dimension of the encoder layers and the pooler layer.
num_hidden_layers (`int`, *optional*, defaults to 28):
Number of hidden layers in the Transformer encoder.
num_attention_heads (`int`, *optional*, defaults to 32):
Number of attention heads for each attention layer in the Transformer encoder.
inner_hidden_size (`int`, *optional*, defaults to 16384):
Dimension of the "intermediate" (i.e., feed-forward) layer in the Transformer encoder.
max_sequence_length (`int`, *optional*, defaults to 512):
The maximum sequence length that this model might ever be used with.
Typically set this to something large just in case (e.g., 512 or 1024 or 2048).
layernorm_epsilon (`float`, *optional*, defaults to 1e-5):
The epsilon used by the layer normalization layers.
use_cache (`bool`, *optional*, defaults to `True`):
Whether the model should return the last key/values attentions (not used by all models).
Example:
```python
>>> from configuration_chatglm import ChatGLMConfig
>>> from modeling_chatglm import ChatGLMModel
>>> # Initializing a ChatGLM-6B THUDM/ChatGLM-6B style configuration
>>> configuration = ChatGLMConfig()
>>> # Initializing a model from the THUDM/ChatGLM-6B style configuration
>>> model = ChatGLMModel(configuration)
>>> # Accessing the model configuration
>>> configuration = model.config

## Supervised datasets collection
We collected 104K bilingual datasets of Chinese and English, and you can find the datasets in this repo
[InstructionWild](https://github.com/XueFuzhao/InstructionWild) and in this [file](https://github.com/XueFuzhao/InstructionWild/blob/main/data/README.md).
Here is how we collected the data
<p align="center">
<img src="https://raw.githubusercontent.com/hpcaitech/public_assets/main/applications/chat/data-collect.png" width=500/>
</p>
### Conversation dataset generation
In order to further improve the model's ability to handle multi-turn conversations, we need to include samples with multi-turn conversations in the dataset. However, the samples in InstructWild and Alpaca datasets currently consist of only single-turn conversations, and their dataset organization is not suitable for storing multi-turn conversations. Additionally, after converting the aforementioned datasets, we also need to include multi-turn conversation datasets like ShareGPT, and we should transform them into the training format supported by ColossalChat.
A sample of conversation dataset should have the following fields:
- `type` (str, optional): The type of the data sample.
- `language` (str, optional): The language of the data sample.
- `dataset` (str, optional): The dataset the data sample originates from.
- `conversations` (str, compulsory): Conversation content of the data sample.
- `id` (int, optional): The ID of the data sample.
A simple example:
```json
{
"type": "instruction",
"language": "English",
"dataset": "Alpaca",
"conversations": [
{
"from": "human",
"value": "Give three tips for staying healthy."
},
{
"from": "gpt",
"value": "1.Eat a balanced diet and make sure to include plenty of fruits and vegetables. \n2. Exercise regularly to keep your body active and strong. \n3. Get enough sleep and maintain a consistent sleep schedule."
}
],
"id": 1
}
```
> **NOTE:** Only key `conversations` is compulsary for training and other keys serve as metadata. The length of `conversations` varies.
You can run the `examples/generate_conversation_dataset.py` to generate a conversation dataset supported by ColossalChat.
You can use the following cmd to generate conversation dataset.
```bash
python generate_conversation_dataset.py \
--dataset "All"
--save_path "/path/to/dataset"
```
## Stage1 - Supervised instructs tuning
Stage1 is supervised instructs fine-tuning, which uses the datasets mentioned earlier to fine-tune the model.
[[Stage1 tutorial video]](https://www.youtube.com/watch?v=-qFBZFmOJfg)
You can run the `examples/train_sft.sh` to start a supervised instructs fine-tuning.
You can also use the following cmd to start a supervised instructs fine-tuning with your own settings.
```bash
torchrun --standalone --nproc_per_node=4 train_sft.py \
--pretrain "/path/to/LLaMa-7B/" \
--model 'llama' \
--strategy colossalai_zero2 \
--save_path /path/to/Coati-7B \
--dataset /path/to/data.json \
--batch_size 4 \
--accumulation_steps 8 \
--lr 2e-5 \
--max_datasets_size 512 \
--max_epochs 1 \
--grad_checkpoint
```
**Note**: the supervised dataset follows the following format,
```json
[
{
"instruction": "Provide a list of the top 10 most popular mobile games in Asia",
"input": "",
"output": "The top 10 most popular mobile games in Asia are:\n1) PUBG Mobile\n2) Pokemon Go\n3) Candy Crush Saga\n4) Free Fire\n5) Clash of Clans\n6) Mario Kart Tour\n7) Arena of Valor\n8) Fantasy Westward Journey\n9) Subway Surfers\n10) ARK Survival Evolved",
"id": 0
},
...
]
```

We train a reward model in stage 2, which obtains corresponding scores by manually ranking different outputs for the same prompt and supervises the training of the reward model.
[[Stage2 tutorial video]](https://www.youtube.com/watch?v=gMx2CApKhuo)
You can run the `examples/train_rm.sh` to start a reward model training.
You can also use the following cmd to start training a reward model.
```bash
torchrun --standalone --nproc_per_node=4 train_reward_model.py \
--pretrain "/path/to/LLaMa-7B/" \
--model 'llama' \
--strategy colossalai_zero2 \

```
### Features and tricks in RM training
- We support [Anthropic/hh-rlhf](https://huggingface.co/datasets/Anthropic/hh-rlhf)and[rm-static](https://huggingface.co/datasets/Dahoas/rm-static) datasets.
- We support 2 kinds of loss function named `log_sig`(used by OpenAI) and `log_exp`(used by Anthropic).
- We change the loss to `valid_acc` and `pair_dist` to monitor progress during training.
- We add special token to the end of the sequence to get better result.
- We use cosine-reducing lr-scheduler for RM training.
- We set value_head as 1 liner layer and initialize the weight of value_head using N(01/(d_model + 1)) distribution.
- We train a Bloom-560m reward model for 1 epoch and find the test acc of the model achieve the performance mentions in [Anthropics paper](https://arxiv.org/abs/2204.05862).
### Experiment result
Model performance in [Anthropics paper](https://arxiv.org/abs/2204.05862):

## Inference example - After Stage3
We support different inference options, including int8 and int4 quantization.
For details, see [`inference/`](https://github.com/hpcaitech/ColossalAI/tree/main/applications/Chat/inference).
## Attention
The examples are demos for the whole training process.You need to change the hyper-parameters to reach great performance.

## Add your own models
If you want to support your own model in Coati, please refer the pull request for RoBERTa support as an example --[[chatgpt] add pre-trained model RoBERTa for RLHF stage 2 & 3](https://github.com/hpcaitech/ColossalAI/pull/3223), and submit a PR to us.
You should complete the implementation of four model classes, including Reward model, Critic model, LM model, Actor model
here are some example code for a NewModel named `Coati`.
if it is supported in huggingface [transformers](https://github.com/huggingface/transformers), you can load it by `from_pretrained`, o
r you can build your own model by yourself.
### Actor model
```python
from ..base import Actor
from transformers.models.coati import CoatiModel
class CoatiActor(Actor):
def __init__(self,
pretrained: Optional[str] = None,
checkpoint: bool = False,
lora_rank: int = 0,
lora_train_bias: str = 'none') -> None:
if pretrained is not None:
model = CoatiModel.from_pretrained(pretrained)
else:
model = build_model() # load your own model if it is not support in transformers
super().__init__(model, lora_rank, lora_train_bias)
```
### Reward model
```python
from ..base import RewardModel
from transformers.models.coati import CoatiModel
class CoatiRM(RewardModel):
def __init__(self,
pretrained: Optional[str] = None,
checkpoint: bool = False,
lora_rank: int = 0,
lora_train_bias: str = 'none') -> None:
if pretrained is not None:
model = CoatiModel.from_pretrained(pretrained)
else:
model = build_model() # load your own model if it is not support in transformers
value_head = nn.Linear(model.config.n_embd, 1)
value_head.weight.data.normal_(mean=0.0, std=1 / (model.config.n_embd + 1))
super().__init__(model, value_head, lora_rank, lora_train_bias)
```
### Critic model
```python
from ..base import Critic
from transformers.models.coati import CoatiModel
class CoatiCritic(Critic):
def __init__(self,
pretrained: Optional[str] = None,
checkpoint: bool = False,
lora_rank: int = 0,
lora_train_bias: str = 'none') -> None:
if pretrained is not None:
model = CoatiModel.from_pretrained(pretrained)
else:
model = build_model() # load your own model if it is not support in transformers
value_head = nn.Linear(model.config.n_embd, 1)
value_head.weight.data.normal_(mean=0.0, std=1 / (model.config.n_embd + 1))
super().__init__(model, value_head, lora_rank, lora_train_bias)
```

| 如何看待当前提前还贷热 | 提前还贷是一种常见的还贷方式,在市场中存在着许多的因素和影响,需要具体分析当前的经济形势和人们心理状况的影响。提前还贷可以帮助借款人早日摆脱债务负担,但也存在一些风险和不确定性。从经济形势来看,当前利率下探、还款压力减轻等因素可能会导致一部分借款人提前还贷。此外,一些购房者可能会受到市场不景气的影响,担心未来房产价值会下降,因此提前还贷以避免资产贬值。从借款人心理状况来看,提前还贷也可能会由于借款人对未来经济预期的不确定性而产生压力和不满。因此,提前还贷并不能一概而论,需要根据具体情况进行分析。如果提前还贷对借款人的经济情况和未来规划造成不利影响,建议谨慎考虑是否要提前还贷。|
