Couldn't load plugin 'Smart_Map' due to an error when calling its classFactory() method

[Kahnthegoodone]

Hello, I have been trying to use Smart-Map (version 1.4.2) in conjunction with QGIS version 3.34, however when I check the box to load the plugin, I get this error: "Couldn't load plugin 'Smart_Map' due to an error when calling its classFactory() method"

I have looked through the closed issues and see that most people experiencing this issue have the wrong versions of GIS or Smart-Map installed. However as far as I am able to discern, I have the correct versions and am still experiencing issues. If there is any other supporting information needed in order to resolve this issue, please let me know.

See error log readout below:

It seems that scikit-learn has not been built correctly.

If you have installed scikit-learn from source, please do not forget
to build the package before using it: run python setup.py install or
make in the source directory.

If you have used an installer, please check that it is suited for your
Python version, your operating system and your platform.

Hello,

The problem may be related to access permission, when the following error appears:

PermissionError: [Errno 13] Permission denied: 'C:\Users\cgoodwin\AppData\Roaming\QGIS\QGIS3\profiles\default
\python\site-packages\sklearn.libs\vcomp140.dll'

It would be advisable to perform the manual installation using the .zip file. Download the .zip file from the QGIS website: https://plugins.qgis.org/plugins/Smart_Map/version/1.4.2/

Unzip the .zip file

Inside the unzipped folder you will find a zipped file with the name: sklearn312.zip

Unzip this folder. Inside the unzipped folder you will find the following folder and file structure:

Copy all these folders and files to the following folder on your computer: C:\Users\cgoodwin\AppData\Roaming\QGIS\QGIS3\profiles\default\python\site-packages\

Before copying, delete all existing files in this folder.

Perform this entire process with QGIS closed.

After deleting the files and copying the unzipped files, open QGIS and check if the plugin is working.

I believe it will work.

Hallo Gustavo,
tried your solution. Sorry but this did not work. Qgis did not find the pandas library. But i'm sure the library is on board. I use Qgis 3.40.1 on windows 11 pro

[sarviovalente]

Please, install LTR version 3.34 (this is the stable version). Best regards Sarvio Em ter., 10 de dez. de 2024 às 13:54, ThomasStruller < ***@***.***> escreveu:
