3 years ago Without more information about 1) your system 2) how you installed pyvkfft it will be difficult to help you. Also 3) you are executing a python file but are not supplying it...
In this case most importantly you may have a cuda issue - are the cuda tools properly installed ? Does pycuda work ? Were there messages during install ?

3 years ago I installed using pip3 install pyvkfft. The install completed with no issues. I havent tested pycuda, but it imports. I frequently use pytorch and cupy without issue though. I have the same error when I clone your code and try to run the benchmark.py file. This is on a linux system and I've installed into a virtualenv. Is there any more information I can give?
Traceback (most recent call last):
File "benchmark.py", line 28, in

3 years ago Does import pyvkfft.opencl work ?
To make a reproducible test, you should test in a fresh virtual environment (you can have weird results if you mix pip install and python setup.py install).
In that fresh environment, install using pip install pyvkfft --verbose --no-cache and copy the details of
the output.
If this does not work, please give an exact list of the command used from the line creating the python virtual env to the commands used to test.

3 years ago I figured out my issue. Your suggestions led me to determine that I had some env variables that caused an issue with the installation of pycuda. Once I sorted those out, I got the install to work. One thing I noticed is that installing pyvkfft will auto install the opencl stuff but it doesnt install cython or pycuda as dependencies. Thanks for the help mate!

Hm, strange (I assume you mean pyopencl and pycuda - cython is not used) - when I install it does list both packages in the requirements (it would only skip pycuda if installation of the cuda extension failed):

When I try to import pyvkfft.cuda I get the following traceback. Any ideas on how to fix this? Thanks.
