ngsolve, module not found

[GlennWSo]

Im trying to create app that depends on ngsolve. My targets are both windows and linux.

To test my that i get the depenencies working i have made a simple pyoxidzer.bzl config. Here a link: https://github.com/GlennWSo/pyoxidzer-learn/blob/ngsolve/pyoxidizer.bzl Bellow here is a snippet from the file:

def make_exe():
    dist = default_python_distribution(python_version="3.9")
    policy = dist.make_python_packaging_policy()
    policy.set_resource_handling_mode("files")
    policy.resources_location_fallback = "filesystem-relative:lib"

    python_config = dist.make_python_interpreter_config()
    python_config.module_search_paths = ["$ORIGIN/lib"]

    exe = dist.to_python_executable(
        name = "python-with-ngsolve",
        packaging_policy = policy,
        config = python_config,
    )

    for resource in exe.pip_download(["pyvista", "ngsolve"]):
        resource.add_location = "filesystem-relative:lib"
        exe.add_python_resource(resource)

    return exe

What i expect when i enter "pyoxidzer run" is a python shell where i can import ngsolve and pyvista. but what happens:

foo@bar:~ $ pyoxidizer run
printing lots of info...
...
Python 3.9.13
Type "help" to ...

>>> import pyvista
>>> print(pyvista.__version)
0.36.1
# pyvista package is working :)

>>> import ngsolve
Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    ModuleNotFoundError: No module named 'ngsolve'
# :(

Any help would be much appreciated!

more probing of the oxidized python shell gives:

>>> import pkg_resources
>>> for pack in pkg_resources.working_set:
...     print(pack)

ngsolve is in this list, so why cant i import it?

[GlennWSo]

update. I found why ngsolve could not be imported. it was not placed in origin/lib but instead in: origin/lib/lib/python3.9/site-packages/lib/ngsolve and some .so files it uses where placed in origin/lib/lib

I dont understand why i get such messy lib tree But i solved my problem by making the fallowing changes: patch
