Public bug reported:
python3-pandas needs certain packages which are not listed among its
dependencies, even as suggests, and are not available in Ubuntu. I ran into
this while using feather. Here's a debug session; earlier import pandas as pd
we executed.
(Pdb) c
> /usr/local/fahydev/Kornak/bifs/examples/investigate09.py(59)<module>()
-> subsample = pd.read_feather(SUBFILE).astype({"id": int})
(Pdb) n
ImportError: Missing optional dependency 'pyarrow'. Use pip or conda to
install pyarrow.
The removal of support for feather and the absence of a suitable package
is noted in the changelog for 0.25.2+dfsg-1.
apache provides packaging and instructions upstream, but it would be
really nice if this just worked.
Note that python3-arrow, an existing Ubuntu package, has absolutely
nothing to do with the pyarrow library.
Desired Outcome:
pyarrow packaged like other python libraries.
The relevant package listed as a dependency of python3-pandas (I'd be fine with
recommends though suggests would do).
In case the info I uploaded didn't get through, this is on Ubuntu 20.04
with python3-pandas 0.25.3+dfsg-7
