Hi all,
Conda 22.9.0 breaks "conda init bash". Conda requires some functions to be present in ~/.bashrc (or equivalent dot file for other shells) in order to function as intended [*]. These functions are added there through "conda init bash", which each conda user should run once.
$ guix shell -C conda sudo
[env]$ conda --version
conda 22.9.0
[env]$ conda init bash
[..]
File "/gnu/store/lvip6h5pamjwmvnkwg60sjb63ph8698k-python-3.9.9/lib/python3.9/subprocess.py", line 19
59, in _communicate
input_view = memoryview(self._input)
TypeError: memoryview: a bytes-like object is required, not 'str'
[...]
However, it seems that this is a conda problem (not sure), and not a guix problem. E.g. see
"conda 22.9.0 breaks bash command prompt"
The suggested solution there is to do "sudo $(which conda) init bash", which is not really acceptable for us.
Also, "conda init bash" does seem to actually do what it is supposed to do: add conda functions to ~/.bashrc; the error occurs after that. So maybe we can just wait this out, or try to see whether it works with conda 22.11.0.
Greetings,
Hugo
[*] There are also some problems in the interplay between guix and the conda functions in .bashrc. I'll report those later.
