NumPy 2 compatibility for tests and tools #1315
Conversation
|
@bnavigator let me know when I should take a look here |
|
I don't think I have anything to add? The test failures seem unrelated. The patch works fine for 4.8.2 here: https://build.opensuse.org/request/show/1198163 |
|
@bnavigator I'd feel better about merging if we could get the tests green. Okay for me to push some commits to your branch to get there? |
|
Sure |
|
Also adding a fix for enthought/apptools#351 |

Okay all green! @prabhuramachandran ready for review/merge from my end. @bnavigator feel free to double-check that I didn't break anything for you.

This took a really long time for me to find. No idea why but on NumPy 2.1 and VTK 9.3+ vtkPoints get created with datatype 12 i.e. VTK_ID_TYPE and it wasn't showing up in the RevPrefixMap for Points, causing a cryptic error:

This fixes it. Not 100% sure it's correct but tests at least pass 🤷
For NumPy 2 compatibility, besides #1303 (yes it makes a difference because of the changed API), the tests and tools need to be adjusted as well.
