You are viewing latest docs which means main branch. If you want to keep to the v0.8.5 release, you should be using stable docs instead.

To use this parser, you'll have to install nightly vLLM instead of v0.8.5

[DenceChen]

install nightly vLLM means:
conda create -n vllm python=3.12 -y
conda activate vllm
git clone https://github.com/vllm-project/vllm
cd vllm
pip install e .
????

or

pip install -U vllm --pre --extra-index-url https://wheels.vllm.ai/nightly

[DenceChen]

pip install -U vllm --pre --extra-index-url https://wheels.vllm.ai/nightly

I installed it using the above instructions, and then deployed a line and still got the following error：

[DarkLight1337]

Oh sorry, maybe the commit is too new to be included in nightly. In that case you might have to install vLLM from source directly

[DenceChen]

Perfect solution：CUDA12.4

conda create -n vllm python=3.12 -y
conda activate vllm
git clone https://github.com/vllm-project/vllm
cd vllm
pip install -e .
