Add option to work with AnalysisBase #6

matthewfeickert · 2022-02-11T21:13:38Z

To be more useful this should also work with ATLAS AnlaysisBase (both release 21 and release 22).

Just the following diff gets things working for AnalysisBase 22.2.61

though for AnalysisBase 21 there are problems as things are still Python 2 there. This is a big problem as the venv module wasn't added to Python until Python 3:

$ docker run --rm python:2.7 /bin/bash -c 'python --version --version; python -m venv --help'
Python 2.7.18
/usr/local/bin/python: No module named venv

Hi Matthew,

This looks great! I really like it and it seems to work very well with python3 and R22. As you mention, setting up python2 with Analysisbase is a real pain. We (myself and a postdoc in Manchester) tried to do this with virtualenv rather than venv, and I think I might have managed to get it to work. The problem is that virtualenv provided on lxplus doesn’t work, and pip2 out-of-the-box fails to install it. The only way I could get it to work was to bootstrap install pip2 locally and then install virtualenv from it with the —ignore-installed flag. Then I replace the line

python3 -m venv "${_venv_name}"

with

/afs/cern.ch/user/m/maly/.local/bin/virtualenv "${_venv_name}"

and I had to comment out the check for CENTOS8 since it tries to use python3. Starting from a fresh-shell, this seems to work.

I'm not sure how one would nicely integrate an bootsrap installation of pip2 in your code though, or if there is a way around that.

Thank you very much,
Mo

matthewfeickert · 2022-03-22T16:25:19Z

@MoAly98 yeah for Python 2 virtualenv is pretty much the only way to go. I think the alternative method of acquiring it, compared to what you show, would be do do something similar to manually downloading and installing virtualenv from the PyPA's bootstrap project. Though that seems like it will also need to be revised as the subdirectory of https://bootstrap.pypa.io/ that was kept for Python 2.7 scripts is gone, and the Python 3 version of virtualenv doesn't work with Python 2 (which is a totally reasonable thing. Python 2 has been EOL for over 2 years).

The problem is that virtualenv provided on lxplus doesn’t work, and pip2 out-of-the-box fails to install it. The only way I could get it to work was to bootstrap install pip2 locally

@MoAly98 can you comment on what you actually did to do a bootstrap install of pip2?

MoAly98 · 2022-03-23T11:26:37Z

The way I did it was:

curl https://bootstrap.pypa.io/pip/2.7/get-pip.py --output get-pip.py
python2 get-pip.py --target=./pip

and then got virtualenv

./pip/bin/pip2.7 install --user virtualenv --ignore-installed

matthewfeickert · 2022-03-23T14:19:51Z

@MoAly98 So I had attempted that before but the method you describe in a Release 21 AnalysisBase environment causes the pip2 to be broken.

$ setupATLAS
$ asetup "21.2.203,AnalysisBase"
$ command -v python2
/cvmfs/atlas.cern.ch/repo/sw/software/21.2/AnalysisBaseExternals/21.2.203/InstallArea/x86_64-centos7-gcc8-opt/bin/python2
$ mkdir py2_debug
$ cd py2_debug
$ curl -sLO https://bootstrap.pypa.io/pip/2.7/get-pip.py
$ python2 get-pip.py --target=./pip
$ ./pip/bin/pip2 --help
Traceback (most recent call last):
  File "./pip/bin/pip2", line 5, in <module>
    from pip._internal.cli.main import main
ImportError: No module named main

Similarly, running get-pip.py directly in a python2 -m pip install sort of way will get virtualenv into a user install by default, but then the resulting virtual environment is broken

$ python2 get-pip.py virtualenv
