[GRASS-dev] error in interactive supervised classification input - update

[Michael Barton]

Apparently no graphs work in the interactive iclass module. Also, it doesn’t seem to work otherwise.

I can mark training fields with no problem. I can export them with no problem.

But when I click the update button, the preview screen goes blank for a bit for each class then returns to the original base raster with nothing showing. The command console displays the following errors (one for each class):

Data error preparing signatures: value (19592) > num of cats
(256)
Data error preparing signatures: value (8089) > num of cats
(256)
Data error preparing signatures: value (11048) > num of cats
(256)
Data error preparing signatures: value (9218) > num of cats
(256)


I’ve looked at the very slim help file and it did not help. Copying Helena and Anna in case they’ve be successful with this working.

Michael

When I try to use g.gui.iclass, I get the error in the attached file. It says it was unable to import matplotlib. Then it says it did find matplotlib but it was the wrong architecture.

If I fire up Python from the GRASS terminal and import matplotlib, it is fine. I also tried to install matplotlib from the terminal in case it would find a correct architecture version. This also went fine.

So I begin to suspect that this is a bug instead of a problem with my systems. Any thoughts?

Mac OS X 10.10.3
GRASS 7.0.2, compliled a week ago.
