Hello, I get the following error when running a supervised classification (I'm trying to make a model and I can't) Traceback (most recent call last): File "C:\Users/jrassan/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\SemiAutomaticClassificationPlugin\interface\classification_tab.py", line 148, in save_classifier_action output = run_classifier(save_classifier=True) File "C:\Users/jrassan/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\SemiAutomaticClassificationPlugin\interface\classification_tab.py", line 487, in run_classifier if output is None: UnboundLocalError: local variable 'output' referenced before assignment

Hello @JoseRascon , it seems an issue related to input data. You may try to split bands using this tool https://semiautomaticclassificationmanual.readthedocs.io/en/latest/split_bands_tab.html and then create a new band set.

JoseRascon commented 3 months ago

Thanks for the help, I have tried separating the bands and joining them again as you told me and the same error continues to appear

I attach what I get when trying with another raster Ha ocurrido un error mientras se ejecutaba el código de Python:

Hello, what images are you using?

Also, please copy the log file as described here (from the creation of the band set) https://semiautomaticclassificationmanual.readthedocs.io/en/latest/faq.html#how-can-i-report-an-error

JoseRascon commented 3 months ago

Hello, I am using Sentinel-2 images corrected without clouds processed in Google Engine (I have tried with normal Sentinel 2 images in case that was the error and nothing) I copy the entire error as you have indicated.

Hello @JoseRascon , it seems that the issue is related to input images and the nodata value -9.223372036854776e+18. You could try to use QGIS raster tools to change the datatype and nodata values of the image.

Hello @JoseRascon , I have a similar problem. I think that It could be useful to compare our data to understand what the common issue is.

JoseRascon commented 3 months ago

Hello, I was testing with other plugins (like Dzetsaka) and the error I was getting was mainly that there were NaN values, once this error was solved it came out perfect. I couldn't verify it with SCP but it could be that this was the problem

Hello, I'm closing this because I checked now that it is a duplicate of https://github.com/semiautomaticgit/SemiAutomaticClassificationPlugin/issues/330. Of course, please continue the reporting here https://github.com/semiautomaticgit/SemiAutomaticClassificationPlugin/issues/330.
