py-pyopencl: TypeError: unsupported type for persistent hash keying: <class 'numpy.dtype[void]'>

Hello,

Two years ago pyopencl was included in the python3.6 and python3.7 packages only. While the 3.6 version works fine, the py37-pyopencl package crashes with the following message :

  File "/opt/local/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pyopencl/__init__.py", line 821, in kernel_set_scalar_arg_dtypes

update : today pyopencl has been ported up to python3.10 but the problem persists for all versions except 3.6

With the pyopencl 2023.1.4, the problem has disappeared from python versions 3.8 to 3.10 (cannot test on 3.7 which is deprecated) The ticket can be closed.

My last comment 3 days ago was on Mac OS 10.12 (Sierra) but on 10.15 (Catalina) no version works! It is a different problem now so I will open a new ticket.

Let's retitle this correctly. There was no crash; there was just an error message.
