I'm trying to pip install this lib but I'm getting the following error:

Looking at it I can understand the problem is because of NPY_ARRAY_UPDATEIFCOPY...

I have a macbook pro m1. I'm trying to install this on python 3 in a conda environment. I tried to export NPY_ARRAY_UPDATEIFCOPY=true but it did not work. Is there any work around? :)

fixed it! follow: https://stackoverflow.com/questions/73060279/installing-elasticdeform-on-mac-m1-error-use-of-undeclared-identifier-npy-ar/73069804#73069804

[gvtulder]

Should be fixed now in the pypi package as well. Thanks!
