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.
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.
