Module 'Numpy' has no attribute 'product' #24

I am not sure if this is related to the current version of nway, but every time I run nway to match two catalogues, I am given the error message Module 'Numpy' has no attribute 'product'. Everything I have looked up thus far suggests an issue with the Numpy version that nway runs with. I currently have Numpy Version 2.0.0 installed on my computer.

Is this something that is happening with others as well, and if so how does the issue get resolved? Do I need to downgrade my numpy so that it is compatible with the demands of using Nway?

Numpy 2.0.0 is very new, and has many breaking changes. Few libraries support it. You may need to downgrade to <2.

probably we have to look at https://numpy.org/doc/stable//numpy_2_0_migration_guide.html and fix some calls, for example np.product is now only available as np.prod.
