Description
Description
Marked as skip here https://github.com/pymc-devs/pytensor/commit/2ab60b39e4622b1d9d677ab3e598d752bd25b17e
I didn't have time to check the reason behind it. It seems scipy is more strict about indptr lengths, and in the gradient we get some cases where the indptr is longer than the rows it has. Perhaps something we can tweak in the perform level

Research direction
Start with the sparse tests skipped in commit 2ab60b39e4622b1d9d677ab3e598d752bd25b17e and reproduce the failures with SciPy 1.16. Inspect the gradient cases involving indptr lengths and the relevant perform-level behavior. Done means the sparse tests pass without the skip while preserving valid indptr and row relationships.
