Unable to import the awkward module in python

[zwu0922]

Hi,

I'm having problem with importing the awkward module in python with the nightly version 2024-10-16. Here is the error message I received when I attempted to import awkward in python:

Python 3.11.9 (main, Sep 20 2024, 11:17:20) [GCC 14.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

Could you please help me fix this issue? Some useful information, including the steps to reproduce the error, can be found below.

Thanks in advance,

• OS version: AlmaLinux 9.4 (Seafoam Ocelot)
• Compiler version: gcc (Spack GCC) 14.2.0
• Reproduced by:

1. Source the nightly version and run python

source /cvmfs/sw-nightlies.hsf.org/key4hep/setup.sh -r 2024-10-16
python

2. Import awkward module in python
   import awkward

• Goal: I would like to be able to import awkward with the latest nightly version.

The workaround is to install importlib-metadata, for example with pip install importlib-metadata --prefix=some/prefix and make sure where the module is installed is in PYTHONPATH. The installation of the module will be in something like some/prefix/lib/python3.11/site-packages.
