test_driver.py failure - "CUDA header does not match"

[jmpolinski]

I am getting the following error when I run "test_driver.py":

`python3 test_driver.py
/usr/local/lib64/python3.6/site-packages/pycuda-2021.1-py3.6-linux-x86_64.egg/pycuda/driver.py:71: UserWarning: Failed to import the CUDA driver interface, with an error message indicating that the version of your CUDA header does not match the version of your CUDA driver.

`

It seems to have something to do with the "_v2" but I'm not sure how to get it working.

_v2

I had the same issue as this, when installing pycuda on a system with an older NVIDIA TITAN V card. The nvidia-smi reported CUDA 10.1, but the conda install of pycuda said no compatible versions were found since pycuda-2020.1 required CUDA >=10.2

By forcing pip install pycuda==2019.1 I seem to have worked around this undefined symbol: cuDevicePrimaryCtxRelease_v2 issue.
