Hello Benjamin/Jack,

Is there a stable setup environment for lxplus? [1] no longer works.

Hi @sihyunjeon I leave this to @BenjaminFuks since I've never used lxplus before.

Hi @sihyunjeon,

I ussed to employ LCG_87/gcc/4.9.3, from which I was creating a fresh virtual environment that I then used for MA5:
python3 -m venv my_env; source my_env/bin/activate; python3 -m pip install scipy click tqdm six jsonschema jsonpatch PyYAML

I however have not used lxplus for months... Maybe something has changed in the meantime.

Cheers,

Benj

So LCG_87/gcc/4.9.3 doesn't work, and I did
source /cvmfs/sft.cern.ch/lcg/views/LCG_100/x86_64-centos7-gcc8-opt/setup.sh
with the python venv commands you gave me and it fails like below.

In the long run, it would be ideal if this can be figured out for LHC/CMS analyzers so that we can support this internally (it's a lot difficult to advocate this within the collaboration if it doesn't work on common computing environment and instead have to rely on individual's personal computing environment)

I'll close this for now if you don't have solutions at the moment!

[sihyunjeon]

Or maybe creating a docker image?

[BFuks]

The one I used was /cvmfs/sft.cern.ch/lcg/releases/LCG_87/gcc/4.9.3/x86_64-slc6.

A docker image may be the way to go, in fact. I however have no experience with this. You may be interested in check this pull request.

Cheers,
