BYOL notebooks fail on fresh setup due to missing `imageio` dependency.

[nikhilchhokar]

Hi ML4Sci team,

I’m trying to run the BYOL self-supervised learning notebooks
(DeepLense_Self_Supervised_Learning_Yashwardhan_Deshmukh → byol_learning → model1_byol).

The notebooks fail in the first cell with:
ModuleNotFoundError: No module named 'imageio'

The notebooks import imageio, but the package is not installed by default and is not
mentioned in any requirements file or setup instructions. As a result, a fresh
environment cannot run the notebooks end-to-end.

I’m happy to add imageio to the dependency list / setup documentation if that aligns
with the maintainers’ preference.

Thanks!

Hi, I was able to reproduce this on a clean setup.
I’m digging into the BYOL notebooks to see what’s missing in the setup and will put together a PR to make the dependencies and instructions clearer so they run end-to-end on a fresh environment.

Thanks for looking into this!
I was able to reproduce the issue on a fresh setup as well and opened #84 to start documenting setup requirements for the BYOL notebooks.
Happy to help review or extend the PR once you’ve identified the missing dependencies / expected setup, or coordinate to avoid overlap.

I'm setting up my local environment and confirmed that imageio is missing. I'd like to work on this and submit a PR to update the dependencies.

The issue was that the BYOL notebooks import imageio, but there was no
requirements.txt provided for this module. On a fresh setup, this causes the
notebooks to fail with a ModuleNotFoundError.

As a beginner, the main difficulty for me was realizing that even after
installing imageio, the error remained because the Jupyter notebook was using
a different Python environment. Once I understood the environment and kernel
mismatch, I added a requirements.txt file to properly declare the dependency,
making the setup easier for new contributors.

Hi, I’d like to work on this issue. May I take it?

Hi, I’ve gone ahead and opened a PR that adds a requirements.txt file for the
mejiro-regression notebooks to address the missing imageio dependency.
