[SciPy-User] Error in scipy sparse: multiplication with coo_matrix copy changes the data and the format of the multiplied

[Juan Nunez-Iglesias]

Actually, I hadn’t, and I realised I hadn’t updated scipy to 1.0, so it was a good chance to try both. I’m on macOS. Indeed, on 0.19 I see the same issue you do, while on 1.0 it is gone.

Incidentally, there’s a few issues related to this that might have been resolved without closing the corresponding GH issue:
https://github.com/scipy/scipy/issues/6902
https://github.com/scipy/scipy/issues/6603

These may have been fixed here:
https://github.com/scipy/scipy/issues/7077
https://github.com/scipy/scipy/pull/7078

Any devs want to comment on these?

Juan.
