Issues importing the necessary modules

[Benny1o1]

When executing the detecter-example notebook, the following error occurred:

---

Would be glad if you can help me out here. Thanks.

Hi Benny, I think this issue is due to an API change in the scipy library. They seperated the public methods form the private ones.

Try to change the import of ~/opt/anaconda3/envs/detectree/lib/python3.10/site-packages/detectree/filters.py

From from scipy.ndimage.filters import _gaussian_kernel1d

To from scipy.ndimage._filters import _gaussian_kernel1d

Hope this helps. Best regards Max

Hi Max,

Thank you for your answer!

Best regards, Benny

I think this issue is due to an API change in the scipy library. They seperated the public methods form the private ones. Try to change the import of ~/[…]/detectree/filters.py

From: from scipy.ndimage.filters import _gaussian_kernel1d

To: from scipy.ndimage._filters import _gaussian_kernel1d

This also works for me, thanks @MaxJarofka I'm not familiar with GitHub, but maybe someone could open a Pull request using the solution cited.

Cheers!

Fixed in detectree PR#13.
