### Quick start - pip This tutorial guides you through every step of running **Yi-34B-Chat locally on an A800 (80G)** and then performing inference. #### Step 0: Prerequisites - Make sure Python 3.10 or a later version is installed. - If you want to run other Yi models, see [software and hardware requirements](#deployment). #### Step 1: Prepare your environment To set up the environment and install the required packages, execute the following command. ```bash git clone https://github.com/01-ai/Yi.git cd yi pip install -r requirements.txt ``` #### Step 2: Download the Yi model You can download the weights and tokenizer of Yi models from the following sources: - [Hugging Face](https://huggingface.co/01-ai) - [ModelScope](https://www.modelscope.cn/organization/01ai/) - [WiseModel](https://wisemodel.cn/organization/01.AI) #### Step 3: Perform inference You can perform inference with Yi chat or base models as below. ##### Perform inference with Yi chat model 1. Create a file named `quick_start.py` and copy the following content to it. ```python from transformers import AutoModelForCausalLM, AutoTokenizer model_path = '[ Back to top ⬆️ ]
### Quick start - DockerMake sure you've installed Docker and nvidia-container-toolkit.
docker run -it --gpus all \
-v <your-model-path>: /models
ghcr.io/01-ai/yi:latest
Alternatively, you can pull the Yi Docker image from registry.lingyiwanwu.com/ci/01-ai/yi:latest.
You can perform inference with Yi chat or base models as below.
The steps are similar to pip - Perform inference with Yi chat model.
Note that the only difference is to set model_path = '<your-model-mount-path>' instead of model_path = '<your-model-path>'.
The steps are similar to pip - Perform inference with Yi base model.
Note that the only difference is to set --model <your-model-mount-path>' instead of model <your-model-path>.
conda-lock to generate fully reproducible lock files for conda environments. ⬇️micromamba for installing these dependencies.
micromamba install -y -n yi -f conda-lock.yml to create a conda environment named yi and install the necessary dependencies.

### Web demo You can build a web UI demo for Yi **chat** models (note that Yi base models are not supported in this senario). [Step 1: Prepare your environment](#step-1-prepare-your-environment). [Step 2: Download the Yi model](#step-2-download-the-yi-model). Step 3. To start a web service locally, run the following command. ```bash python demo/web_demo.py -c[ Back to top ⬆️ ]
### Fine-tuning ```bash bash finetune/scripts/run_sft_Yi_6b.sh ``` Once finished, you can compare the finetuned model and the base model with the following command: ```bash bash finetune/scripts/run_eval.sh ```[ Back to top ⬆️ ]
### Quantization #### GPT-Q ```bash python quantization/gptq/quant_autogptq.py \ --model /base_model \ --output_dir /quantized_model \ --trust_remote_code ``` Once finished, you can then evaluate the resulting model as follows: ```bash python quantization/gptq/eval_quantized_model.py \ --model /quantized_model \ --trust_remote_code ```[ Back to top ⬆️ ]
### Deployment If you want to deploy Yi models, make sure you meet the software and hardware requirements. #### Software requirements Before using Yi quantized models, make sure you've installed the correct software listed below. | Model | Software |---|--- Yi 4-bit quantized models | [AWQ and CUDA](https://github.com/casper-hansen/AutoAWQ?tab=readme-ov-file#install-from-pypi) Yi 8-bit quantized models | [GPTQ and CUDA](https://github.com/PanQiWei/AutoGPTQ?tab=readme-ov-file#quick-installation) #### Hardware requirements Before deploying Yi in your environment, make sure your hardware meets the following requirements. ##### Chat models | Model | Minimum VRAM | Recommended GPU Example | |:----------------------|:--------------|:-------------------------------------:| | Yi-6B-Chat | 15 GB | 1 x RTX 3090 (24 GB)[ Back to top ⬆️ ]
