QGIS 3

[fresm]

Bonjour Nicolas,

is your tool compatible with QGIS 3?

Hello,
Not yet, but it is planned, i hope a few weeks max after Qgis 3 will be out.

Dzetsaka for qgis 3 is now out. Feel free to try and leave me a feedback.
Algorithms in the Processing toolbox are much more efficient now thanks to qgis 3.

I'm getting several errors with qgis3 for osx.
Gaussian model trains fine. but I cannot predict - It will not load the "model learned" from the training session. Is there a specific extension needed?

Running a Random Forest training I get the error
Traceback (most recent call last): File "/Users/knussear/Library/Application Support/QGIS/QGIS3/profiles/default/python/plugins/dzetsaka/processing/train.py", line 161, in processAlgorithm mainfunction.learnModel(INPUT_RASTER.source(),INPUT_LAYER.source(),INPUT_COLUMN[0],OUTPUT_MODEL,SPLIT_PERCENT,0,OUTPUT_MATRIX,SELECTED_ALGORITHM,feedback=feedback) File "/Users/knussear/Library/Application Support/QGIS/QGIS3/profiles/default/python/plugins/dzetsaka/scripts/mainfunction.py", line 230, in init yp = model.predict(xt) UnboundLocalError: local variable 'model' referenced before assignment

Hello @knussear,
did you test with the samples ? Tell me if it works with GMM algorithm when using the samples I gave you (https://github.com/lennepkade/dzetsaka/archive/docs.zip). I'll look closer anyway.
When using GMM, you do not have to install a specific extension.
Thanks.

Hi Nicolas

I have a similar issue as mentioned above. when I run the random forest classifier I get the following:

An error has occurred while executing Python code:

I have used the GMM algorithm but want the RF algorithm to compare. I used the sample/demo map and train data you provided. I also created my own training vector as a trail. Please advise what I could be doing wrong?

thank you in advance for your help

The plugin is opening QGIS several times in an uncontrolled manner in MacOS Mojave. Until we open a project, QGIS keeps on opening replicas. After the plugin works fine. however, only GMM and K-means algorithms are working.
Thanks in advance. Very nice and easy to use plugin.
