Can't compile the custom cauchy kernel about s4 HOT 3 CLOSED

Were you able to resolve this? I can't reproduce this error with a few different environments.

Aside from the test_cauchy.py test script, does the end-to-end code run using the extension? If the code throws an error or you see the warning

CUDA extension for cauchy multiplication not found. Install by going to extensions/cauchy/ and running `python setup.py install`. This should speed up end-to-end training by 10-50%

then your installation did not work, otherwise it installed correctly.

If it does not work, does the pykeops solution work?

I have resolved this issue by reinstall cuda tookit, thank for your response!!

I have the exact same issue as the original poster, on Python 3.10 in my case.

warning: install_lib: 'build/lib' does not exist -- no Python modules to install is the operable line.

The issue is that https://github.com/HazyResearch/state-spaces/blob/06dbbdfd0876501a7f12bf3262121badbc7658af/extensions/cauchy/setup.py#L7 does not give an error if CUDA isn’t available / paths aren’t set.

On Sherlock, I had to do:

> ml cuda/11.7
> ml gcc

and then the install succeeds
