First, install recommended compiler. We recommend to use `gcc/g++ >= 12.3.0` as the default compiler to avoid potential problems. For example, on Ubuntu 22.4, you can run:
|
||
|
|
|
||
|
|
```console
|
||
|
|
sudo apt-get update -y
|
||
|
|
sudo apt-get install -y gcc-12 g++-12 libnuma-dev
|
||
|
|
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-12 10 --slave /usr/bin/g++ g++ /usr/bin/g++-12
|
||
|
|
```
|
||
|
|
|
||
|
|
Second, install Python packages for vLLM CPU backend building:
|
||
|
|
|
||
|
|
```console
|
||
|
|
pip install --upgrade pip
|
||
|
|
pip install cmake>=3.26 wheel packaging ninja "setuptools-scm>=8" numpy
|
||
|
|
pip install -v -r requirements-cpu.txt --extra-index-url https://download.pytorch.org/whl/cpu
|
||
|
|
```
|
||
|
|
|
||
|
|
Finally, build and install vLLM CPU backend:
|
||
|
|
|
||
|
|
```console
|
||
|
|
VLLM_TARGET_DEVICE=cpu python setup.py install
|
||
|
|
```
