Note, this can be avoided by specifying the error_on_import=True argument to lazy_loader.load, but it does seems unnecessary that pandas is crawled when not_found is not a subpackage of pandas.
It looks like the problem is that inspect.stack()[1] causes the lazy modules to be accessed. I'm not sure exactly why, but figuring out the answer to that question is how progress can be made on this issue.
