jupyter cell output cluttered with empty output with unknown origin

See original GitHub issue

The problem

docarray mapping functions in jupyter notebooks (VS Code and original jupyter) seem to produce empty output that is printed to the cell output.

This leads to the cell output becoming extremely long and error messages etc very hard to locate.

The empty output for a short loop: empty-output

The empty output seems to scale with the number of loop iterations.

Attempted solutions

Read the documentation carefully (I’m new to docarray 😁 ). But didn’t find a reference.

Set show_progress = False where possible (although apparently already the default). But unsurprisingly this didn’t help.

Minimal example to reproduce the behavior

Happy about any pointers! 😄

Hi @samsja ,

the environment.yml says:

  - jupyter=1.0.0=py39hf3d152e_7
  - jupyter_client=7.0.6=pyhd8ed1ab_0
  - jupyter_console=6.4.4=pyhd8ed1ab_0
  - jupyter_core=4.10.0=py39hf3d152e_0
  - jupyterlab_widgets=1.1.1=pyhd8ed1ab_0

I think to get the same env one could use:

git clone https://github.com/eschmidt42/docarray-cell-output-issue.git (contains an environment.yml and poetry files,
cd into the new dir,
conda: conda env create -f environment.yml or
poetry (my default): poetry install with the pyproject.toml and poetry.lock in your directory.

Thank you all for looking at this! 😁
