mlserver-* ROCKs cannot be built

Debugging.

Experimentation involved two Ubuntu VMs.

On Ubuntu 22.04:

$ mkdir test
$ ls -la test
drwxrwxr-x 2 4096 Sep  6 14:09 .
drwxrwxr-x 9 4096 Sep  6 14:09 ..
$ pip --version
pip 22.3.1
$ pip install --prefix ./test/ ./chardet-3.0.4-py2.py3-none-any.whl 
Processing ./chardet-3.0.4-py2.py3-none-any.whl
Installing collected packages: chardet
Successfully installed chardet-3.0.4
$ ls -la test/
drwxrwxr-x 3 4096 Sep  6 14:10 .
drwxrwxr-x 9 4096 Sep  6 14:09 ..
drwxrwxr-x 4 4096 Sep  6 14:10 local
$ ls -la test/local/
drwxrwxr-x 4 4096 Sep  6 14:10 .
drwxrwxr-x 3 4096 Sep  6 14:10 ..
drwxrwxr-x 2 4096 Sep  6 14:10 bin
drwxrwxr-x 3 4096 Sep  6 14:10 lib

local/ directory is created under test/ (which was supplied via --prefix) in which bin/, lib/, etc. are installed. It seems that in pip 22.3.1 --prefix option is not handled as described in documentation:

On Ubuntu 20.04:

$ mkdir test
$ ls -la test
drwxrwxr-x 2 4096 Sep  6 14:09 .
drwxrwxr-x 9 4096 Sep  6 14:09 ..
$ pip --version
pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.8)
$ ls -la test/
total 16
drwxrwxr-x 1 4096 Sep  6 14:28 .
drwxrwxr-x 1 4096 Sep  6 14:28 ..
drwxrwxr-x 1 4096 Sep  6 14:28 bin
drwxrwxr-x 1 4096 Sep  6 14:28 lib

bin/ and lib/ created directly under test/, no extra directory was created, i.e. no local/ under test/
This behaviour is aligned with pip documentation on handling of --prefix option.

Another small test on 22.04:

$ python3
Python 3.10.12 (main, Jun 11 2023, 05:26:28) [GCC 11.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from pip._internal.locations import _distutils, _sysconfig
>>> _sysconfig.get_scheme('click', prefix='myprefix').purelib
'myprefix/local/lib/python3.10/dist-packages'
>>> _distutils.get_scheme('click', prefix='myprefix').purelib
'myprefix/lib/python3.10/site-packages'

Do you know the version of pip on the log?

[orfeas-k]

Keeping it open until there is a fix for the pip issue.

[orfeas-k]

Closing since it looks like they can be built now, if we add a python-is-python3 package (although unrelated to this issue)

[orfeas-k]

Reopening since the previous comment wasn't exactly true. They could be built because we were using base: [email protected] instead of 22.04 as suggested by this issue.
