I upgraded to numpy 1.23.5 and now it works, i.e. numba 0.56.4 requires numpy 1.23.5 (or at least not numpy 1.23.2).

[gusbacos]

Worked

[biglimp]

I have numba=0.56.4 and numpy 1.20.2 and it works.

[j3r3m1]

How do we solve this exception ? Setting a given numpy and numba version ? But then it might affect other dependencies

[nilswallenberg]

There is a new version of numba, 0.57.0, (released 1 May). Tried it with numpy 1.23.2 and it works. Not sure about other numpy versions though...

[nilswallenberg]

Also tried reinstalling numba 0.56.4 and now it works with numpy 1.23.2....

[j3r3m1]

Should now be solved
