#1 Updated by Giovanni Manghi almost 6 years ago

  • Status changed from Open to Feedback

Is that in the GRASS plugin or in the Processing toolbox? is the whole QGIS that crashes?

#2 Updated by Daniel Morton almost 6 years ago

Calling i.pca from the processing toolbox. The whole of Qgis crashes.

#3 Updated by Giovanni Manghi almost 6 years ago

  • Category changed from GRASS to Processing/GRASS

Can you please attach sample data and parameters you are using? thanks.

#4 Updated by Giovanni Manghi almost 6 years ago

  • Crashes QGIS or corrupts data changed from No to Yes
  • Subject changed from grass not working on qgis 3.4.2 to ProcessingGRASS module causes QGIS to crash
  • Priority changed from Normal to High

#5 Updated by Daniel Morton almost 6 years ago

To clarify.

This happens when batch processing is chosen. When you select run the dialog freezes indefinitely. If you chose to close it whilst in this state the whole of QGIS crashes.

If not run in batch mode the pca works as expected.

  • Subject changed from ProcessingGRASS module causes QGIS to crash to Processing/batch mode freezes QGIS

This happens when batch processing is chosen. When you select run the dialog freezes indefinitely. If you chose to close it whilst in this state the whole of QGIS crashes.

this depends on the input data/paramters?

or in batch mode also happens when you a process 2 times with inputs and parameters that work ok if run not in batch?

#7 Updated by Daniel Morton almost 6 years ago

The data I used are quite large. Too big to send as an attachment. However, I have found a simpler route to the problem, that requires no data nor altering the default parameters.

Start QGIS. From the processing toolbox select grass, i.pca. Select 'Run as Batch Process...' . Don't bother to specify any data or change the default parameters, just press 'Run'. Nothing happens now. Press 'Close'. QGIS now crashes (on my system).

Out of curiosity I tried this with some other grass processes. It happens whenever I try and use batch processing fro rasters or imagery.

Note these problems apply to 3.4.2 (not 3.4.1). The issue reporting tool drop down does not provide 3.4.2.

#8 Updated by Daniel Morton almost 6 years ago

The same problem occurs in 3.5.0

Duplicate of #20650

#11 Updated by Daniel Morton almost 6 years ago

There is a different problem in 2.18, as per #20655. Neither work as expected.
