After using the docker image of NVIDIA to create a container, installing pycuda in the container encountered the following error:

environment

issue

@inducer Does pycuda not support using in containers?

I haven't tried myself, but I haven't heard any complaints. Can you run other CUDA software in the container? How about Nvidia's SDK samples that use the driver API?

You may have more success asking on the mailing list for people's experience. At any rate, your error message points more towards a software installation problem.
