Requirements - Pykerberos, Numba, Scikit-image

[d-dimos]

I think the requirements.txt file should be checked for version validity problems.

Trying: pip install -r requirements.txt yields errors concerning the numba, scikit-image and pykerberos packages.

pykerberos's issue is Q&Aed here: https://github.com/requests/requests-kerberos/issues/109

Both scikit-image and numba, run on Colab, output:

Not sure, but I think it is due to version upgrades. I fixed it by changing scikit-image's version to 0.14.0 and numba's to 0.39.0

Still testing the repo, though, to check if everything is working fine.
