Numba incompatibility

[philippeller]

With numba 0.45.1 I git the totally cryptic error:
Type of #4 arg mismatch: i1 != i32
After googleing it turns out to be a numba bug: numba/numba#5051
So we need numba 0.47

That's not what I understand from that discussion, though?

TypeError: Type of #4 arg mismatch: i1 != i32 suggests you have Numba 0.46 in use with llvmlite=0.31, these are incompatible releases. Please try either upgrading Numba to 0.47 or downgrading llvmlite to 0.30. Working combinations are Numba 0.46 + llvmlite 0.30, OR, Numba 0.47 + llvmlite 0.31. Thanks.

Seems like if you have compatible llvmlite and numba versions, this isn't a problem. Can you try 0.45.1 but with (IIRC, but I could be wrong) llvmlite 0.29?

I just confirmed, 0.45.0 and 0.45.1 were designed with llvmlite 0.29.0dev0 in mind. Therefore, 0.29.0 from pip (or whatever package manager you use) should work. If you still have the above issue, then we can bump the required numba version up.

Aha, fair enough. I upgraded numda which then worked for me.
Let's just keep this around for reference then
