rok opened a new pull request, #46423: URL: https://github.com/apache/arrow/pull/46423
### Rationale for this change As per [SciPy's migration guide](https://scipy.github.io/devdocs/reference/sparse.migration_to_sparray.html) it would be good to change the constructors we use when creating scipy's sparse object. Further we should allow for creating sparse arrow objects from `scipy.sparray` (currently only `scipy.spmatrix)` objects and test for it. ### What changes are included in this PR? This adjusts `pa.SparseCXXMatrix` constructors and `pa.SparseCXXMatrix.to_scipy` to achieve goals listed above and adds tests. ### Are these changes tested? Yes. ### Are there any user-facing changes? `pyarrow.coo_matrix.to_scipy` and `pyarrow.csr_matrix.to_scipy` would now return different types (sparray instead of spmatrix) which would probably be a breaking change (behaviors of the types would be similar). Additionally `pa.SparseCXXMatrix.from_scipy` would now take `scipy.sparray` and `scipy.spmatrix` which would not be a breaking change. -- This is an automated message from the Apache Git Service.
