• How did you install Nuitka and Python

  I am using Anaconda Python; Nuitka was installed via python -m pip install nuitka

• The specific PyPI names and versions

  We have many different dependencies in this project, but here are a few:

numpy                         1.20.3
pandas                        1.3.4
pydantic                      1.8.2
scikit-learn                  0.24.2

Problem

I am new to Nuitka (very cool solution) and am trying to compile an entire package into a single executable file. I attempted to do so with a command like this, from within a directory where the code for the package (which hasn’t been otherwise installed or compiled yet) lives:

python -m nuitka --module package --include-package=package

After running that command, I find the following in my directory:

drwsrwsr-x 1 owner users   4096       Oct 24 20:52 package
drwsrwsr-x 1 owner users   65536      Oct 24 20:59 package.build
-rw-rw-r-- 1 owner users   6823728    Oct 24 21:00 package.cpython-39-x86_64-linux-gnu.so
-rw-rw-r-- 1 owner users   5819       Oct 24 21:00 package.pyi

I then take the original package folder and rename it to to something like package_code so as to avoid a namespace collision. If I enter a Python terminal and try to import package, I get the following error:

ImportError: /home/user/code/package.cpython-39-x86_64-linux-gnu.so: undefined symbol: _PyObjectDict_SetItem

I can’t find much online around the error I’m having, except for something else pertaining to scikit-learn, which is a dependency of package. I also see that _PyObjectDict_SetItem is mentioned in the Nuitka Roadmap.

My first question is: must I use --follow-imports in order to Nuitka-compile all dependencies, or is it possible to Nuitka-compile only my package, which would then make use of other .py dependencies that it might import?

The solution for the issue is on develop and will be part of the next release.
