For example, you can install ccache via either conda install ccache or apt ```bash $ pip install --upgrade pip $ # Install PyTorch $ pip uninstall torch -y $ pip install --no-cache-dir --pre torch==2.5.0.dev20240726 --index-url https://download. →pytorch.org/whl/nightly/rocm6.1 control behavior: - VLLM_OPENVINO_KVCACHE_SPACE to specify the KV Cache size (e.g, VLLM_OPENVINO_KVCACHE_SPACE=40 means 40 GB space for KV cache), larger setting will allow vLLM running more requests in parallel
