Import sv module

[Shion Matsumoto]

Hi,

I have been working with the sv Python module and was wondering if I could import the sv module much like I would import numpy or some other Python module. Currently

Code: Select all

from sv import *

only works if I run the script using

Code: Select all

sv --python -- script.py

, but I would like to be able to run the script in the same way as I would run any other Python script so that I can debug the scripts. Would something like this be possible or would you recommend another way to debug scripts?

Best,
Shion

Hi Shion,

The SV Python API can only be used within the SV Python environment. Running sv --python puts you in the SV Python interpreter. You can then run and debug scripts interactively. For example (on a Mac)

Code: Select all

$ sv --python
