🐛 Bug

Hi,
When I import the intensity_normalization API in python(3.9.10), some errors happened and I don't know how to fix them, could you please help me to solve the problem.

from intensity_normalization.normalize.fcm import FCMNormalize

Errors:

Also, this error happened when i

from intensity_normalization.typing import Modality, TissueType

Environment

• intensity-normalization version (e.g., 0.3.8): 2.2.3
• numpy version (e.g., 1.0):1.21.5
• OS (e.g., Linux): Linux
• How you installed intensity-normalization (conda, pip, source): from source
• Build command you used (if installed from source): python setup.py install
• Python version: 3.9.10
• Any other relevant information:

Additional context

I believe this is a numpy version; numpy v1.22 is required. Re-open if that doesn't fix the issue.
