This looks like it would work! @miranov25, are you able to test from this git branch or do we need to make an Uproot release for testing?

[miranov25]

@jpivarski, @ianna, Thank you. I am packing now. Tomorrow morning we will leave for our holiday. I quickly checked your branch, but I have some problems I installed via pip from the GitHub branch. I assume that was ok.
I assume some headed file is missing (something similar we had 4in September test):

    fix: specialize type_to_name

(venv3) Singularity> pip install /u/miranov/github/awkward/ 
Processing /u/miranov/github/awkward

(venv3) Singularity> pip show awkward
Name: awkward
Version: 2.0.2

I cannot rule out the possibility that I have done something wrong. Next time I will be able to check in 3-5 days.

@miranov25 installing directly from Git via pip is not supported. Instead, you need to clone the repo before running a prepare script. E.g., to build the awkward packages from Git into a wheels directory

this_path=$PWD
pushd $(mktemp -d)

git clone --depth=1 --recurse-submodules --shallow-submodules https://github.com/scikit-hep/awkward.git
cd awkward

pipx run nox -s prepare

mkdir -p "$this_path/wheels" 
pipx run  --python $(which python3) build -w -o "$this_path/wheels" awkward-cpp
pipx run  --python $(which python3) build -w -o "$this_path/wheels" .
