I'm currently working on a PySide6 project and using Nuitka to compile it (pyside6-deploy command) During the build process, I encounter a warning, and at runtime, I face an ImportError related to NumPy. Here are the details:
When building the project, Nuitka outputs the following warning:
Nuitka-Plugins:WARNING: dll-files: DLL configuration by filename code for 'numpy' did not give a result. Either conditions are missing, or this version of the module needs treatment added.
Despite this warning, the build completes successfully.
However, when I execute the built project, I encounter the following ImportError:
ImportError: Error importing numpy: you should not try to import numpy from its source directory; please exit the numpy source tree, and relaunch your python interpreter from there.
The error suggests that the project is incorrectly trying to import NumPy from its source directory, but I've verified that I'm not running the project from within the NumPy source directory.
Hereunder, you can find a minimal reproducible example. Numpy is embedded in NumPy here but I'm also using it directly in some other modules of the package. To then build my environment I use the following command:
pyside6-deploy --name DICON -v -f .\main.py
For the involved libraries and python I have the following versions:
Python 3.10.13
Numpy 1.26.4
Here is the minimal example:
import sys
import os
sys.path.insert(0, os.path.realpath(os.path.join(os.path.dirname(__file__), "..")))
import numpy as np
if __name__ == "__main__":
print(np.linspace(0,100,100))
After executing the build command this is the output that I receive:

Questions:
Based on Nuitka issue #2113, I figured that my issue was being caused by the fact that I used pip to install Numpy. So I uninstalled using pip uninstall numpy and then installed it again using conda install numpy. This solved my issue with the DLL's.
