Windows 11 Pro 24H2
QGIS 3.44.9 (LTR)
Python 3.12.13 (bundled with QGIS)
NumPy 2.4.3 (bundled with QGIS)
Deepness 0.6.5
Also reproduced on QGIS 3.30.2
Problem
Deepness installation completes, but the plugin cannot initialize correctly because OpenCV (cv2) fails to load.
Investigation performed
Tested with a completely fresh QGIS profile.
Same problem reproduced on both QGIS 3.44.9 and QGIS 3.30.2.
Verified that Deepness installs its dependencies into:
%APPDATA%\QGIS\QGIS3\profiles\python\plugins\deepness\python3.12
The requirements.txt shipped with Deepness contains:
numpy<2.0.0
opencv-python-headless<=4.9.0.80
onnxruntime-gpu<=1.17.0
QGIS 3.44.9 ships with NumPy 2.4.3.
Observed errors
Initial cv2 import error:
ImportError:
ERROR: recursion is detected during loading of "cv2" binary extensions.
Check OpenCV installation.
Additional findings
The newly installed cv2 directory appeared incomplete and was missing:
config.py
config-3.py
An older backup copy of the cv2 directory contained these files.
After replacing the newly installed cv2 directory with the older complete version, the recursion error disappeared and a different error appeared:
A module that was compiled using NumPy 1.x cannot be run in NumPy 2.4.3
ImportError:
numpy.core.multiarray failed to import
QGIS Python environment
Python version:
3.12.13
NumPy version:
2.4.3
NumPy location:
C:\Program Files\QGIS 3.44.9\apps\Python312\Lib\site-packages\numpy
Conclusion
The issue appears to be related to dependency compatibility:
Deepness requirements explicitly require numpy<2.0.0.
QGIS 3.44.9 provides NumPy 2.4.3.
The installed OpenCV build appears to have been compiled against NumPy 1.x and cannot load with NumPy 2.x.
Additionally, the installed cv2 package may be incomplete because required configuration files were missing after installation.
Expected behaviour
Deepness should either:
install a dependency set compatible with QGIS Python 3.12 + NumPy 2.x, or
isolate its own dependency environment so that NumPy/OpenCV version conflicts do not occur.
Please let me know if additional logs or dependency listings are needed.
Die Plugin-Version 0.6.5 ist offiziell für QGIS bis 3.99 freigegeben.
In deiner lokalen requirements.txt steht jedoch ausdrücklich:
numpy<2.0.0
opencv-python-headless<=4.9.0.80
während QGIS 3.44 bereits NumPy 2.4.3 mitliefert. Das ist der stärkste technische Hinweis auf die Ursache des Problems.
