Getting an error in Google Colab

[mowshon]

I'm trying to run the example from Google Colab, which is linked in the repository, I don't change anything, I leave the same default values that are specified there.

Google Colab: https://colab.research.google.com/github/Bellingcat/ShadowFinder/blob/main/ShadowFinderColab.ipynb

But I get this error:

ValueError                                Traceback (most recent call last)

numpy/random/mtrand.pyx in init numpy.random.mtrand()

ValueError: numpy.dtype size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject

Thanks for raising this!

There is a workaround which is to run the cell, get the error, and then restart the Colab session (Runtime -> Restart Session).

This comes about because the default version of some dependency (probably numpy) has changed in Colab since the last release of ShadowFinder, but the pip install command that runs when the tool installs isn't correctly downgrading the package, a session restart causes the downgrade to be applied.

This will be fixable when basemap releases their v2.0.0 which will be "soon"

matplotlib/basemap#604 (comment)

In #29 I deprecated basemap and have tweaked the output. This is all fixed now! 🎉
