Patches vLLM 0.6.3 to register Qwen3CoderToolParser under the name "qwen3_coder".
|
||
|
|
|
||
|
|
Deploy steps on the remote machine (already called by patch_ops.sh):
|
||
|
|
1. cp qwen3coder_tool_parser.py \
|
||
|
|
/usr/local/corex/lib/python3/dist-packages/vllm/entrypoints/openai/tool_parsers/
|
||
|
|
2. python3 patch_vllm_tool_parser.py
|
||
|
|
|
||
|
|
Usage after patching:
|
||
|
|
--tool-call-parser qwen3_coder --enable-auto-tool-choice
