Historically ob-python has been a bit broken, especially sessions. Earlier this year, I started taking care of ob-python and implemented some fixes [1], which will land in 9.4. When that's released, I plan to update the outdated worg documentation [2]. > I've barely use python with org-mode and I would need some help with > the python setup.

Basically, you need to manually call plt.savefig(), then return the filename. > In R things seems to be smoother. Yes, ob-R is in much better shape. In addition to plotting, returning dataframes works (pandas DataFrames are not yet supported in ob-python). I also much prefer the way ob-R returns lists as a column vector instead of a row vector. > there are ob-* all over the place.

Scimax [4] also has a maintained fork of ob-ipython, though I haven't tried it. My goal is to make ob-python a serious alternative to these external ob-* packages eventually. Here are some of the improvements I have in mind: - Improved plotting - Support for pandas DataFrames and numpy Arrays - Async session evaluation [5] I've been delayed working on this as I've gotten very busy due to the pandemic (I am a bioinformaticist working on SARS-CoV-2 sequencing). But I'm hoping to make a bit of progress this week, as I'm on vacation and unable to go outside due to the smoke from the California fires. It's unclear to me if we're in a feature freeze, so I'm currently pushing ob-python development to a separate branch [6], which I'll cherry pick into master after the Org 9.4 release.
