[nbdime] - Image hashes change on every run

[Vishnu V. Krishnan]

The hashes associated with images seems to be new each time I run the cell, irrespective of whether there have been any changes in the data from which the images are generated. This results in a polluted diff that's harder to parse for actual changes.

Is there any way to fix this?

Thanks!

Yes. Check out the nbdev tool: https://www.fast.ai/posts/2022-08-25-jupyter-git.html

They mention this problem explicitly:

> For every figure, such as a plot, Jupyter includes not only the image itself in the notebook, but also a plain text description that includes the id (like a memory address) of the object, such as <matplotlib.axes._subplots.AxesSubplot at 0x7fbc113dbe90>. This changes every time you execute a notebook, and therefore will create a conflict every time two people execute this cell

and how to solve it.

Best,

Thanks Jonathan, I will check that out.
