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
```
<h3>Installation</h3>
1. Use a Docker image, see [documentation for Docker](./doc/en/Docker.md)
2. You can install using Pypi (for linux):
```
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.
3. Or you can 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```
- Compile and install (for Linux)
```
bash install.sh
```
- Compile and install(for Windows)
```
install.bat
```
4. 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 that 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). We use the DeepSeek-V2-Lite-Chat-GGUF model as an example here. But we also support other models, you can replace it with any other model that you want to test.
<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).

```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>

```
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).

# Muti-GPU
Assume you have read the [Injection Tutorial](./injection_tutorial.md) and have a basic understanding of how to inject a model. In this tutorial, we will show you how to use KTransformers to run a model on multiple GPUs.
If you have multiple GPUs, you can set the device for each module to different GPUs.
DeepseekV2-Chat got 60 layers, if we got 2 GPUs, we can allocate 30 layers to each GPU. Complete multi GPU rule examples [here](https://github.com/kvcache-ai/ktransformers/blob/main/ktransformers/optimize/optimize_rules/DeepSeek-V3-Chat-multi-gpu.yaml).
<p align="center">

</picture>
</p>
First of all, for multi-GPU, we have to inject an new operator `KDeepseekV2Model`. And set division of the layers to different GPUs. For our case, we have to set the `transfer_map` in the `KDeepseekV2Model` operatoras as follows:
```yaml
- match:
name: "^model$"
replace:
class: "ktransformers.operators.models.KDeepseekV2Model"
kwargs:
transfer_map:
30: "cuda:1"
```
And we have to set the device for each module in the model.
For example, for `routed experts`, the yaml for one GPU is:
```yaml
- match:
name: "^model\\.layers\\..*\\.mlp\\.experts$"
replace:
class: ktransformers.operators.experts.KTransformersExperts # Custom MoE kernel with expert parallelism
kwargs:
generate_device: "cuda:0"
generate_op: "MLPCUDAExperts"
out_device: "cuda:0"
recursive: False # Don't recursively inject submodules of this module
```
But for two GPUs, we need to set the device for each module in the model.
```yaml
# allcate 0-29 layers‘s out_device to cuda:0
- match:
name: "^model\\.layers\\.(0|[1-9]|[12][0-9])\\.mlp\\.experts$"
replace:
class: ktransformers.operators.experts.KTransformersExperts # custom MoE Kernel with expert paralleism
kwargs:
generate_device: "cpu"
generate_op: "KExpertsCPU"
out_device: "cuda:0"
recursive: False # don't recursively inject submodules of this module
# allocate 30-59 layers‘s out_device to cuda:1
- match:
name: "^model\\.layers\\.([345][0-9])\\.mlp\\.experts$"
replace:
class: ktransformers.operators.experts.KTransformersExperts # custom MoE Kernel with expert paralleism
kwargs:
generate_device: "cpu"
generate_op: "KExpertsCPU"
out_device: "cuda:1"
recursive: False # don't recursively inject submodules of this module
```
For other modules, we can set the device in the same way.
# How to fully utilize multi-GPU's VRAM
When you have multiple GPUs, you can fully utilize the VRAM of each GPU by moving more weights to the GPU.
For example, for DeepSeekV2-Chat, we can move the weights of the experts to the GPU.
For example, the yaml for two GPUs is:
```yaml
- match:
name: "^model\\.layers\\.(0|[1-9]|[12][0-9])\\.mlp\\.experts$"
replace:
class: ktransformers.operators.experts.KTransformersExperts
kwargs:
generate_device: "cpu"
generate_op: "KExpertsCPU"
out_device: "cuda:0"
recursive: False
```
But we got extra 60GB VRAM on cuda:0, we can move experts in layer 4~8 to cuda:0.
```yaml
# Add new rule before old rule.
- match:
name: "^model\\.layers\\.([4-8])\\.mlp\\.experts$" # inject experts in layer 4~8 as marlin expert
replace:
class: ktransformers.operators.experts.KTransformersExperts
kwargs:
generate_device: "cuda:0"
generate_op: "KExpertsMarlin"
recursive: False
- match:
name: "^model\\.layers\\.(0|[1-9]|[12][0-9])\\.mlp\\.experts$"
replace:
class: ktransformers.operators.experts.KTransformersExperts
kwargs:
generate_device: "cpu"
generate_op: "KExpertsCPU"
out_device: "cuda:0"
recursive: False
```
Adjust the layer range as you want. Note that:
* The loading speed will be significantly slower for each expert moved to the GPU.
* You have to close the cuda graph if you want to move the experts to the GPU.
* For DeepSeek-R1/V3, each expert moved to the GPU will consume approximately 6GB of VRAM.
* The first matched rule in yaml will be applied. For example, if you have two rules that match the same layer, only the first rule's replacement will be valid.
