Scipy library

[Stesperti]

I encountered an issue with the latest version of SciPy: csr_array objects no longer have the getnnz attribute, as this function was deprecated in earlier versions and is not implemented in the current one. While the getnnz method is still available for csr_matrix, it is not supported for csr_array. Indeed, the community file (in the tutorial folder) worked without issues only with older versions of SciPy.
I would suggest either specifying a compatible version of SciPy in the requirements file to avoid confusion or updating the implementation to support the latest version.

Best,
Stefano

Hi Stefano, thanks a lot for reporting this! I'll fix the code to be compatible with the last scipy version.
