I'm just trying to import scipy and I'm getting this error:

Traceback (most recent call last):
File "/private/var/mobile/Containers/Shared/AppGroup/1701F3DE-82C4-468E-9C3E-657A36868569/Pythonista3/Documents/site-packages/scipy/init.py", line 97, in
from scipy.config import show as show_config
ImportError: No module named 'scipy.config'

During handling of the above exception, another exception occurred:

What should i do?

You might want to use the search feature on this forum and read some of the 50+ posts on SciPy.

In short: SciPy is not included with Pythonista, and it is also not possible to install it yourself for technical reasons (e.g. the fact that you don't have a compiler on iOS, and cannot run unsigned code without jailbreak).

I am getting the same import error on import numpy and it IS part of pythonista. Is there an explanation for this?

@dwullery Can you copy and paste the full traceback for the error? It's impossible that it is exactly the same error, since the OP's error explicitly mentions scipy in the error message.

Also, you should try force-restarting Pythonista. (Double-click the home button, swipe Pythonista away to the top, then start Pythonista again from the home screen.) Sometimes when you stop a script while it is importing a module, it can get stuck in a half-imported state that causes lots of errors. The best way to fix that is to fully restart the app.

It sounds like you copied the source folder for scipy into your Python path somewhere. That won't work, since scipy needs to be compiled; you'll have to install it, either via python setup.py install from the source directory, pip/easy_install
