it didn't use correct nvcc path when installing apex #1657

Closed yz103 closed 1 year ago

yz103 commented 1 year ago

which nvcc show that the path for nvcc is /usr/local/cuda/bin/nvcc

when running "python setup.py install --cuda_ext --cpp_ext "

how could I solve this problem? Thank you very much for your help.

Would you know the correct path to nvcc installed into your environment?

At glance that duplicate "bin" looks not good though.

yz103 commented 1 year ago

Yeah, the path to nvcc is /usr/local/cuda/bin/nvcc

I know something is messed up for the nvcc path but haven't figured it out yet.

so the installed path itself looks quite common.

Could you check some environment variables that could have something to do with, for example, CUDA_HOME and PATH are correctly set?

Thank you very much for your comments.

echo $CUDA_HOME /usr/local/cuda/bin echo $PATH /home/dell/.vscode-server/bin/ee2b180d582a7f601fa6ecfdad8d9fd269ab1884/bin/remote-cli:/home/dell/anaconda3/envs/retmol/bin:/home/dell/anaconda3/condabin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/usr/local/cuda/lib64:/usr/local/cuda/extras/CPUTI/lib64:/usr/local/cuda/bin:/usr/local/cuda/lib64:/usr/local/cuda/extras/CPUTI/lib64:/usr/local/cuda/bin

could you try CUDA_HOME=/usr/local/cuda?

yz103 commented 1 year ago

Yeah it can find cuda now. Thank you very much for your help.

Best wishes, Yiwei
