Error with pyparsing when no CUDA is found #45
Description
Line 104 in 6782a64
This line assumes that pyparsing has been imported, but it is not imported in the setup.py script.
This appears to be a transitive dependency of pyclibrary, and cuda-python's setup.py expects version 2.4.7. However, the latest version of pyclibrary has a much looser pinning on pyparsing>=2.3.1,<4: https://github.com/MatthieuDartiailh/pyclibrary/blob/1d4dbfc207afee3fd80b72e94c60d47d8263d49a/setup.py#L48
As of this writing, the latest pyparsing is 3.0.9. https://github.com/pyparsing/pyparsing/releases/tag/pyparsing_3.0.9
I'm not sure how to reconcile this. Is the error message out of date? Does a dependency on pyparsing need to be added? Is pyparsing 3.0.9 allowable or not?
Here is an example traceback I encountered while attempting to package cuda-python for CUDA 12 on conda-forge (work in progress: conda-forge/cuda-python-feedstock#33).
