You can verify your environment by running `python -m lmdeploy.pytorch.check_env.triton_custom_add`.

When running python -m lmdeploy.pytorch.check_env.triton_custom_add it will show error

/usr/bin/ld: cannot find -lcuda: No such file or directory
collect2: error: ld returned 1 exit status
Traceback (most recent call last):

To solve it, symbolic link

sudo ln -s /usr/local/cuda-12.2/targets/x86_64-linux/lib/stubs/libcuda.so /usr/lib64/libcuda.so

Then

❯ python -m lmdeploy.pytorch.check_env.triton_custom_add                                         
Done.
