# How to Run DeepSeek-R1 In this document, we will show you how to install and run KTransformers on your local machine. 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 if [ -d "/usr/local/cuda/bin" ]; then export PATH=$PATH:/usr/local/cuda/bin fi if [ -d "/usr/local/cuda/lib64" ]; then export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64 # Or you can add it to /etc/ld.so.conf and run ldconfig as root: # echo "/usr/local/cuda-12.x/lib64" | sudo tee -a /etc/ld.so.conf # sudo ldconfig fi if [ -d "/usr/local/cuda" ]; then export CUDA_PATH=$CUDA_PATH:/usr/local/cuda fi ``` - Linux-x86_64 with gcc, g++ and cmake (using Ubuntu as an example) ```sh sudo apt-get update sudo apt-get install build-essential cmake ninja-build ``` - We recommend using [Miniconda3](https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh) or [Anaconda3](https://repo.anaconda.com/archive/Anaconda3-2024.10-1-Linux-x86_64.sh) to create a virtual environment with Python=3.11 to run our program. Assuming your Anaconda installation directory is `~/anaconda3`, you should ensure that the version identifier of the GNU C++standard library used by Anaconda includes `GLIBCXX-3.4.32` ```sh conda create --name ktransformers python=3.11 conda activate ktransformers # you may need to run ‘conda init’ and reopen shell first conda install -c conda-forge libstdcxx-ng # Anaconda provides a package called `libstdcxx-ng` that includes a newer version of `libstdc++`, which can be installed via `conda-forge`. strings ~/anaconda3/envs/ktransformers-0.3/lib/libstdc++.so.6 | grep GLIBCXX ``` - Make sure that PyTorch, packaging, ninja is installed You can also [install previous versions of PyTorch](https://pytorch.org/get-started/previous-versions/) ``` pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu126 pip3 install packaging ninja cpufeature numpy ``` - At the same time, you should download and install the corresponding version of flash-attention from https://github.com/Dao-AILab/flash-attention/releases. ## Installation * 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](./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.
the detailed usage of makefile is [here](./makefile_usage.md)

Local Chat

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).

Run Example

```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: .safetensors 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).
