Functions aren't working for me

[Banzir2]

I'm sure I've done something dumb, but for some reason when I import from uncertainties.umath import * it doesn't actually import any functions (sin, exp, tan, etc). I've tried upgrading every version. Am I missing a package?

This works for me:

from uncertainties.umath import *

print(sin)
#<function _wrap.<locals>.f_with_affine_output at 0x000002D5928B69D0>

What exactly do you see if you try the simple snippet above? I doubt the issue has to do with any versions. I would guess it more likely has to do with something about your python environment, such as how you are installing uncertainties. How are you installing uncertainties?

I used pip

I can't help debug more without you providing more information. See the other question I asked in my first response. Also: what if you do from uncertainties.umath import sin instead of from uncertainties.umath import *?

Ok, it looks like a problem with the IDE. The IDE shows an error even though there is none. I tried running the snippet despite the IDE error and it prints correctly.

@Banzir2 ah, that makes sense. The import structure in uncertainties is a bit... strange... right now. This strangeness makes it hard for modern IDEs to do lots of the cool static code inspection that they can do. We should modernize the import structure to be more compatible with modern IDEs.
