# How to Run DeepSeek-R1
In this document, we will show you how to run the local_chat.py script to test the DeepSeek-R1's performance. There are two versions: 
* V0.2 is the current main branch.
* V0.3 is a preview version only provides binary distribution for now.
* To reproduce our DeepSeek-R1/V3 results, please refer to [Deepseek-R1/V3 Tutorial](./DeepseekR1_V3_tutorial.md) for more detail settings after installation.
## Preparation
Some preparation:

- CUDA 12.1 and above, if you didn't have it yet, you may install from [here](https://developer.nvidia.com/cuda-downloads).
  
  ```sh
  # Adding CUDA to PATH
  export PATH=/usr/local/cuda/bin:$PATH
  export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH
  export CUDA_PATH=/usr/local/cuda
  ```

- Linux-x86_64 with gcc, g++ and cmake
  
  ```sh
  sudo apt-get update
  sudo apt-get install gcc g++ cmake ninja-build
  ```

- We recommend using [Conda](https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh) to create a virtual environment with Python=3.11 to run our program.
  
  ```sh
  conda create --name ktransformers python=3.11
  conda activate ktransformers # you may need to run ‘conda init’ and reopen shell first
  ```

- Make sure that PyTorch, packaging, ninja is installed
  
  ```
  pip install torch packaging ninja cpufeature numpy
  ```

## Installation

<!-- 1. ~~Use a Docker image, see [documentation for Docker](./doc/en/Docker.md)~~
   
   >We are working on the latest docker image, please wait for a while.

2. ~~You can install using Pypi (for linux):~~
    > We are working on the latest pypi package, please wait for a while.
   
   ```
   pip install ktransformers --no-build-isolation
   ```
   
   for windows we prepare a pre compiled whl package on [ktransformers-0.2.0+cu125torch24avx2-cp312-cp312-win_amd64.whl](https://github.com/kvcache-ai/ktransformers/releases/download/v0.2.0/ktransformers-0.2.0+cu125torch24avx2-cp312-cp312-win_amd64.whl), which require cuda-12.5, torch-2.4, python-3.11, more pre compiled package are being produced.  -->

* Download source code and compile:
   
   - init source code 
     
     ```sh
     git clone https://github.com/kvcache-ai/ktransformers.git
     cd ktransformers
     git submodule init
     git submodule update
     ```

   - [Optional] If you want to run with website, please [compile the website](./doc/en/api/server/website.md) before execute ```bash install.sh```

   - For Linux
     - For simple install:
     
        ```shell
        bash install.sh
        ```
     - For those who have two cpu and 1T RAM:

        ```shell
        # Make sure your system has dual sockets and double size RAM than the model's size (e.g. 1T RAM for 512G model)
        export USE_NUMA=1
        bash install.sh # or `make dev_install`
        ```

   - For Windows
     
     ```shell
     install.bat
     ```

* If you are developer, you can make use of the makefile to compile and format the code. <br> the detailed usage of makefile is [here](./doc/en/makefile_usage.md) 

<h3>Local Chat</h3>
We provide a simple command-line local chat Python script that you can run for testing.

> Note: this is a very simple test tool only support one round chat without any memory about last input, if you want to try full ability of the model, you may go to [RESTful API and Web UI](#id_666). 

<h4>Run Example</h4>

```shell
# Begin from root of your cloned repo!
# Begin from root of your cloned repo!!
# Begin from root of your cloned repo!!! 

# Download mzwing/DeepSeek-V2-Lite-Chat-GGUF from huggingface
mkdir DeepSeek-V2-Lite-Chat-GGUF
cd DeepSeek-V2-Lite-Chat-GGUF

wget https://huggingface.co/mzwing/DeepSeek-V2-Lite-Chat-GGUF/resolve/main/DeepSeek-V2-Lite-Chat.Q4_K_M.gguf -O DeepSeek-V2-Lite-Chat.Q4_K_M.gguf

cd .. # Move to repo's root dir

# Start local chat
python -m ktransformers.local_chat --model_path deepseek-ai/DeepSeek-V2-Lite-Chat --gguf_path ./DeepSeek-V2-Lite-Chat-GGUF

# If you see “OSError: We couldn't connect to 'https://huggingface.co' to load this file”, try：
# GIT_LFS_SKIP_SMUDGE=1 git clone https://huggingface.co/deepseek-ai/DeepSeek-V2-Lite
# python  ktransformers.local_chat --model_path ./DeepSeek-V2-Lite --gguf_path ./DeepSeek-V2-Lite-Chat-GGUF
```

It features the following arguments:

- `--model_path` (required): Name of the model (such as "deepseek-ai/DeepSeek-V2-Lite-Chat" which will automatically download configs from [Hugging Face](https://huggingface.co/deepseek-ai/DeepSeek-V2-Lite)). Or if you already got local files  you may directly use that path to initialize the model.  
  
  > Note: <strong>.safetensors</strong> files are not required in the directory. We only need config files to build model and tokenizer.

- `--gguf_path` (required): Path of a directory containing GGUF files which could that can be downloaded from [Hugging Face](https://huggingface.co/mzwing/DeepSeek-V2-Lite-Chat-GGUF/tree/main). Note that the directory should only contains GGUF of current model, which means you need one separate directory for each model.

- `--optimize_rule_path` (required except for Qwen2Moe and DeepSeek-V2): Path of YAML file containing optimize rules. There are two rule files pre-written in the [ktransformers/optimize/optimize_rules](ktransformers/optimize/optimize_rules) directory for optimizing DeepSeek-V2 and Qwen2-57B-A14, two SOTA MoE models.

- `--max_new_tokens`: Int (default=1000). Maximum number of new tokens to generate.

- `--cpu_infer`: Int (default=10). The number of CPUs used for inference. Should ideally be set to the (total number of cores - 2).

<h3>RESTful API and Web UI (deprected) </h3>


Start without website:

```sh
ktransformers --model_path deepseek-ai/DeepSeek-V2-Lite-Chat --gguf_path /path/to/DeepSeek-V2-Lite-Chat-GGUF --port 10002
```

Start with website:

```sh
ktransformers --model_path deepseek-ai/DeepSeek-V2-Lite-Chat --gguf_path /path/to/DeepSeek-V2-Lite-Chat-GGUF  --port 10002 --web True
```

Or you want to start server with transformers, the model_path should include safetensors

```bash
ktransformers --type transformers --model_path /mnt/data/model/Qwen2-0.5B-Instruct --port 10002 --web True
```

Access website with url [http://localhost:10002/web/index.html#/chat](http://localhost:10002/web/index.html#/chat) :
