nbdev_update creates a new cell, instead of updating the original code

[BirkhoffG]

nbdev_update does not work as intended. It will create a new code cell, instead of updating the original code.

My use case:

• python_module
  • a.py
  • b.py
  • ...
• nbs
  • a.ipynb
  • b.ipynb
  • ...

If I make changes in a.py, and run nbdev_update, it will create a new code cell in a.ipynb, rather than updating code in this notebook.

version: 2.1.1

Thanks for reporting this. I'm getting a different error: the code gets updated into the same cell, but it becomes a markdown cell without any directives.

@BirkhoffG do you mind sharing a repo or minimal example

[BirkhoffG]

Hi @hamelsmu, here is my repo:
https:/BirkhoffG/counternet_jax

To reproduce the error:

1. make some changes in CounterNetTrainingModule in cfnet/training_module.py.
2. cd cfnet
3. nbdev_update training_module.py

@BirkhoffG I believe your project is a nbdev v1 repo. Have you tried migrating this project to nbdev v2 yet? Here is a migration guide: https://nbdev.fast.ai/migrating.html

Can you please try that and let us know if that helps?

[BirkhoffG]

Yes, at the time I reported the bug, I was using the v2 nbdev. I manually downgrade to v1 for now as this bug persists.

The snyc module in v2 seems to have some problems (e.g., #769), so I downgrade to v1 for now.

To replicate the issue reported, go to the refactor branch, which is using nbdev v2.
