Error in using the Zernike moments.

[M-I-Dx]

I am trying to get Zernike moments for some images but I keep getting the following error

AttributeError                            Traceback (most recent call last)
<ipython-input-33-6eb9b0e4463a> in <module>()
----> 1 get_moments(img, 10)

<ipython-input-32-b3923b47676f> in get_moments(image, radius)
      1 def get_moments(image, radius):
----> 2     moments = mahotas.features.zernike_moments(image, radius)
      3     return moments

AttributeError: module 'mahotas' has no attribute 'features'

Can you suggest the fix for this?

What does your file look like? Did you import mahotas.features before this code?

[M-I-Dx]

If I import mahotas.features instead of just mahotas, I get the following error:

/usr/local/lib/python3.7/dist-packages/mahotas/features/__init__.py in <module>()

ImportError: numpy.core.multiarray failed to import

Does import numpy work on your system? This is some messed up installation. How did you install mahotas?

[M-I-Dx]

Yes, import numpy works. I am running it on google colabs. For installing mahotas, I just used pip install mahotas.

Sorry, this seems like a messed up environment and I do not have any insights.

Ok. Thanks for your time. I will try it on my local system.
