Issue with GeoAI plugin launch: DLL load failed & geoai_external attribute error & failed to load model: Meta SAM3 is not available

[Nik-17P]

Hello, Qiusheng Wu,

I am reaching out regarding an issue I’ve encountered while trying to run the GeoAI plugin. I would greatly appreciate your guidance in resolving it.

Environment:

OS: Windows 10 (Russia)
Installation methods tested:
via Conda
via OSGeo4W Shell
Problem description:
After following the installation instructions, I observed the following behavior:

On the first launch via OSGeo4W Shell, the Moondream VLM module worked, but SamGeo failed to load.
I have not yet tested the Segmentation tool due to limited VRAM.
The issues seem to have emerged after package updates.
Error messages:

Failed to load model:
DLL load failed while importing lib: Не найдена указанная процедура.
Failed to load model:
module 'geoai_external' has no attribute 'MoondreamGeo'
Failed to load model: Meta SAM3 is not available. Please install it as:
pip install segment-geospatial[samgeo3]

Additional context:

We experience difficulties downloading models from Hugging Face in Russia, but we have found workarounds.
The model was successfully downloaded during the first launch, but now it fails to load via the module.
I intend to use your developments for scientific purposes and would very much like to get the plugin working.
Questions:

1. Could you please suggest possible causes for the DLL import failure and the missing attribute error?
2. Are there known compatibility issues with recent package updates?
3. Are there any specific steps to manually verify or repair the model/module linkage?
   Thank you very much for your time and assistance. I look forward to your reply.

Best regards,
Pochemin Nikita

Hi, I have also encountered the same issue "pip install segment-geospatial[samgeo3]" within QGIS, I managed to get it working within a normal python environment (samgeo, geoai etc) however in QGIS it refuses to work... I managed to sort out my torch issue by updating gpu drivers but still nothing... my environment is :
RTX 5070 GPU, Python 3.12

If this is a wider bug woth QGIS, please let me know thanks

Thank you!
It turns out that I was not approved for access to SAM3. I didn't double-check, I thought everything was fine. But then there remains the problem with moondreams2, as the error does not disappear.

Failed to load model:
DLL load failed while importing lib: The specified procedure was not found.
Failed to load model:
module 'geoai_external' has no attribute 'MoondreamGeo'

As I understand it, there is a problem of library version compatibility. Dll problems occur when importing transformers tools:

ImportError: DLL load failed while importing lib: Не найдена указанная процедура.

[Nik-17P]

The result of solving the problem with importing transformers and pyarrow into QGIS
The problem with the DLL load failed error when importing the transformers and pyarrow libraries in the QGIS environment was solved in two stages. The root cause is the classic binary dependency conflict in Windows when using Conda.

What solved the problem
Stage Problem Solution Result

1. Resolving the conflict The pyarrow DLL was installed from PyPI (pip), not from Conda. On Windows, binary builds from these sources were incompatible due to the use of different compilers (MSVC), which caused the DLL load failed error. Removing the pip version with the pip uninstall pyarrow command and installing a compatible version from the conda-forge channel with the --strict-channel-priority flag. The pyarrow and scikit-learn libraries were imported without errors.
2. Restoring the integrity of QGIS When reinstalling pyarrow, the Conda manager was forced to roll back QGIS and dozens of dependencies (GDAL, NumPy, etc.) to older versions to resolve conflicts. This disrupted internal communications, and QGIS stopped seeing Python. Reinstalling the current version of QGIS with the command conda install qgis --force-reinstall. This returned all packets to a consistent state. QGIS has started up again, and its Python interpreter and plug-ins (including GeoAI) are working.
   , Key conclusion
   In the Conda environment for Windows, it is critically important to install all complex binary packages (such as pyarrow, numpy, scikit-learn, qgis, gdal) from a single channel (preferably conda-forge) and never mix them with installations from PyPI. Using the --strict-channel-priority flag helps ensure this.

, Short instructions for the future
To avoid similar problems when working with GeoAI and QGIS in Conda:

Always install packages via Conda:
Use conda install -c conda-forge , especially for libraries with C/C++ components.

Use pip only as a last resort.:
Only for packages that are not in the Conda repositories. If you are using pip, do this after installing all the Conda packages.

Follow the official instructions when creating an environment for GeoAI:
Install all key packages (qgis, transformers, pyarrow, geoai) with a single command from conda-forge to ensure version compatibility.

Thus, the solution was to bring the entire environment to a consistent state, where all binary dependencies are compiled by one compiler and compatible with each other.

Here are the key commands that solved the problem with importing transformers and pyarrow into QGIS, in the order in which they were executed:

1. Diagnosis (identification of the root of the problem)
   bash

Checking the installation source of the problematic

conda list | findstr pyarrow package
The result showed: pyarrow 14.0.2 pypi_0 pypi — the package was installed from PyPI, not from Conda, which caused a DLL conflict.

2. Troubleshooting the DLL conflict
   bash

Removing an incompatible version from PyPI

pip uninstall pyarrow -y

Installing a compatible version from conda-forge with channel priority

conda install -c conda-forge --strict-channel-priority pyarrow=14.0.2
The --strict-channel-priority flag is critically important so that all dependencies are pulled up from conda-forge.

3. Restoring QGIS (if it has stopped seeing Python)
   After reinstalling pyarrow, Conda could have rolled back the QGIS version, disrupting the environment.

bash

Forced reinstallation of the current version of QGIS

conda install -c conda-forge --strict-channel-priority qgis --force-reinstall
