Message_ix/Jupyter/Git Version Control and execution_count

[jasper...@googlemail.com]

Dear all,

in our group we keep all members updated through Gitkraken.

One thing that hinders us is that Jupyter writes an execution_count in the ipynb. Thus even if I commit just a single line of code, Gitkraken/Tortoise shows hundreds of lines of modified code, i.e these updated execution_count numbers.

Is there a way to make it more obvious, where the 'real coding' has been done?

Best regards

Jasper

Hi Jasper,

Thanks for pinging the list! Unfortunately, the Jupyter notebooks are not the best medium for file-based version control for exactly the reason you mention. It is possible to use some save hooks to clear out these things (here is one source on how to do that [1]), but it may be a bit daunting. The short answer is don't save notebooks in version control with output (you can always "clear output" before saving) or move the bits of analysis that are commonly used into a separate script and version control that. The longer answer is look to [1] for other solutions.

Cheers,

Matt
