ModuleNotFound in node where job lands

[maxgalli]

This issue is partially related to #234.
Thanks to @luisfdez, htmap now seems to work on lxplus.
However, I'm getting an error that I don't fully understand when I try to run this script.

As you can see, the function that I feed htmap.map with is dummy_extractor, which inside uses the method uproot.open. When I run the script, I get the following:

$ python3 htmap_dummy_samples.py --base-dir /eos/home-g/gallim/samples/dummy_samples                                                                                     [294/1832]

==========  End error report for component 0 of map ripe-quick-robe  ===========

Setup

The setup I'm using consists in a patched version of htmap (installed with /usr/bin/python3 setup.py install --user after cloning this branch) while uproot was as well installed manually (since it is not installed in the default directories and I don't have privileges to install it there) and its path is the following:

>>> import uproot
>>> uproot.__file__
'/afs/cern.ch/user/g/gallim/.local/lib/python3.6/site-packages/uproot/__init__.py'

What I tried

As you can see, in the list of the installed packages there is no uproot. However, if I run python3 -m pip freeze --disable-pip-version-check, it is shown.
I also tried the same procedure within a conda environment, with htmap installed in the same way I described, and I get the same problem.
Another thing I tried was to modify the function that I feed htmap.map with, by not calling uproot.open and simply make it return an int (but, I point out, keeping import uproot at the beginning of the script). In this case I don't see the error.

Do you know any idea of what I could try?
Please let me know if you need some more details.

@luisfdez suggestion to add htmap.settings["DELIVERY_METHOD"] = "assume" worked, hence closing
