Error running unit test

[Jack]

Hi, I'm trying to run the unit tests with "./tests/test_manager.py -p A" but I get this error after it's been running for a bit, any idea what's going wrong exactly? It says there's an error report in /tmp/acc_test_mg5ab0iq4vi/MGPROC/Events/run_01/unweighted_events.lhe.gz_0.lhe_tag_1_debug.log, but I looked and couldn't find these folders.

I saw a similar error, in another post due to numpy not being downloaded, but I can see my numpy version from command line so I don't think that's the issue here?

Any idea if I'm missing a dependency or something would be great

Hi,

./tests/test_manager.py -p A
are acceptance test.

In this case the test crashing is related to the running of reweighting which needs f2py.
I do not have the full screen log and looks like I miss the real error. So my guess is that the issue is that it might be a python2/python3 issue. If your default f2py is related to python2 then you will get an issue since by default madgraph is running with python3.

So this is my best guess of the issue.

Cheers,

Olivier

I've copied the text into a .txt document. I tried checking for updates with "pip3 list -o | cut -f1 -d' ' | tr " " "\n" | awk '{if(NR>=3)print)' | cut -d' ' -f1 | xargs -n1 pip3 install -U" (which I found looking up how to update my python modules) but that hasn't helped.

I'm also running on an ubuntu emulator on a windows machine, so I don't know if that'll cause problems

So the "real" error is this one:
> /tmp/tmpzsfecpg0/src.linux-x86_64-3.8/all_matrix2pymodule.c:18:10: fatal error: Python.h: No such file or directory
> 18 | #include <Python.h>
> | ^~~~~~~~~~
> compilation terminated.

on ubuntu this is typically fixed by doing
sudo apt install python3-dev

(but note I do not run on ubuntu so I can not test that command(

Cheers,

Olivier
