I pip installed openslide-python before, but I am still having an issue. I also tried installing it with a GitHub clone, but that didn’t work. How should I solve this issue?
Since the monai package of monailabel requires openslide-python 1.1.2 as stated here, then I would suggest using Python 3.10 or earlier as there are only Whl files available for those versions. See openslide-python · PyPI. Python 3.11 was not released when this openslide version was released so it is not officially supported.
