Thank you for your reply.

Could you check the build logs


Do you mean to check all logs when I build docker image?
(It’s very long. So I can’t find where I should check.)



 ptrblck:

see if the CUDA toolkit was detected and used?


I checked nvcc -V in system environment and docker container.
In system environment, I can detect CUDA toolkit.
In docker container, command return nvcc: command not found.
Other docker container (that can use GPU) return same message.
Is there something wrong in my all Dockerfile?
