PyViennaCL installation using pip.

[Peter-Fayez95]

I am trying to install PyViennaCL on Windows 10 (64-bit) and I am using Python 3.9.6. Using pip install pyviennacl, the error I received at first was that Visual C++ needed is version 14.0 or higher, I solved this issue by downloading vs buildtools. Now, I receive this error in the pip log.

The output states Check the logs for full command output. Can you please provide that?

(unfortunately I don't know buildtools well, so I can't give specific instructions on how to get that full output.

Hello Thanks a lot for your response and help. I downloaded the python library in binary form (As I will be using it as it is) and downloaded an older version of python (3.6) to install the .whl file using pip and it worked.
