SEED_SPLIT_UQ OverflowError on PC

[spasmann]

I'm running into the error below on all MC/DC runs but only on my desktop PC. Everything runs fine on my Mac laptop.

Traceback (most recent call last):

OverflowError: Python int too large to convert to C long

I'd bet this is an environment issue. Few questions:

1. Is this windows or wsl or linux?
2. can you run conda list in your current env and reply with the results

Is the error suggesting that SEED_SPLIT_UQ = nb.uint(0x5368656261) is too large?

This looks like a known standing issue on WIndows (see [1], [2]). I think the solution should be to change this line to nb.unint64 instead of nb.uint

[jpmorgan98]

If this is the solution @clemekay or @braxtoncuneo please comment on if this screws with the hashing at all

This suggested change fixed the bug. Submitted a PR and will close the issue.
