Patches the vLLM model registry and deploys the Qwen3_5 model file.
|
|
|
|
Deploy steps on the remote machine:
|
|
1. patch_ops.sh locates vLLM with importlib.util.find_spec.
|
|
2. cp modified_scripts/qwen3_5.py into the detected vllm model directory.
|
|
2. python3 modified_scripts/patch_vllm_qwen3_5.py
|
|
|
|
The registry patch installs Qwen3.6 aliases so /model/config.json does not
|
|
need to be edited by hand.
