Multi-threading does not work but easy fix

[Sanseviria]

Hey,
this is a super useful package!
I needed to increase the speed of the code and set num_threads = -1 (any number other than 1 will break the code).
In bootstrap.py in line 272: "for seed in _np.random.randint(0, 232 - 1, num_threads):" will break as it exceeds the max signed int. If you change it to 231 - 1 it will work fine.
Thanks!

Hi,
what about this issue? Is this software still maintained by someone?
Just asking because I like to use software that is maintained and fixes bugs when reported.
Thanks
Philip
