When does this happen?

IF ImportError: undefined symbol __nvJitLinkComplete_12_4 when importing torch after installing vllm (e.g., vllm 0.6.3.post2.dev386) which pulls torch 2.5.1.

How others solved it

THEN Downgrade torch to version 2.4.0 which is known to work with vllm 0.6.3.post1. Alternatively, apply workaround from PyTorch issue #111469 (e.g., set LD_PRELOAD to a compatible libnvJitLink.so) or wait for PyTorch fix in a future release.

pip install torch==2.4.0 --force-reinstall
