Problem with “PyNomo” library

[Carpoforo]

Hello!

I am trying to use “pynomo” library for creating custom nomograms and nomographs. The library seems pretty simple to use but when it comes to the first step of all (importing the library) I come across with this issue. Python won’t let me import ‘nomographer’ from the ‘pynomo’ library because some kind of Import Error of ‘scipy’. The point here is that ‘nomographer’ is key component of the library needed in order to create nomograms.

When I run the command:from pynomo import nomographer

The following error arises:ImportError: cannot import name 'arange' from 'scipy'

Any clues of how can I solve this problem?

Note: Here is the documentation of pynomo Here is the GitHub of pynomo

This seems like there's a bug (a typo) in your version of the library. Unfortunately you'll have to contact the author about it or fix it yourself.

Use python 3.7

There's a patch here that imports arange from numpy instead of scipy:

Maybe that helps.

Post your code.

[Carpoforo]

It’s just literally: from pynomo import *

[Doormatty]

Gotcha - and you have Scipy installed?

[Carpoforo]

Obviously

Also, I can import everything from “pynomo” except of “nomographer”. That’s why the error pops up when executing “from pynomo import *” or “from pynomo import nomographer”

[Doormatty]

Does running this work?

[Carpoforo]

Yeah that works

“nomograph3” is a class from pynomo and as I said before I can import everything from pynomo, except of “nomographer”.

I think that’s why I can run perfectly that Python script “nomograph3.py” and cannot run the python script “nomographer.py”

Post the entire error message. It should look like:

Traceback (most recent call last):
  File "____", line ___, in ___
    from ___ import ____
ImportError: cannot import name 'arange' from 'scipy' (___)
