A clear and concise description of what you expected to happen.

Desktop (please complete the following information):

• OS: M1 MacOS Ventura 13.5.2
• Python version: 3.9.16

Additional context
I thought it was interesting that it does find scikit-image even though its import is skimage. Though I guess that was fixed #83
