Background

I installed pycuda with pip install pycuda==2020.01 and it installed without any errors.

However when running the code, I got the following error.

in <module> from pycuda._driver import * # noqa 
SystemError: initialization of _driver raised unreported exception

appartenly importing pycuda itself was causing error.

Fix

I removed the install pycuda.

pip uninstall pycuda

downloaded pycuda source files(version 2020.01) and build&installed it from source.

$ tar xzf pycuda-2020.1.tar.gz
$ cd pycuda-2020.1
$ python configure.py --cuda-root=/usr/local/cuda
$ make install

After doing this, the above error did not occur.
