RuntimeError: Cuda extensions are being compiled with a version of Cuda that does not match the version used to compile Pytorch binaries. Pytorch binaries were compiled with Cuda 10.1.
In some cases, a minor-version mismatch will not cause later errors: https://github.com/NVIDIA/apex/pull/323#discussion_r287021798. You can try commenting out this check (at your own risk).

Exception information:

I am getting this error in my stacktrace when trying for (many times to install apex) Does this mean that I have to change CUDA version ? I f yes how ?

Should I use pip to reinstall cuda ??

Start with setup.py and the check_cuda_torch_binary_vs_bare_metal call shown in the traceback; inspect how the local CUDA version and PyTorch binary version are checked. Reproduce the listed installation command in the same Python 3.7 environment, and treat a successful Apex installation without the version-mismatch error as done.
