While running classification : Error exception: 'str' object has no attribute 'dataProvider' #59

I created several polygones in order to use the classification algorithm. I can run the classification but close to the end of the processing, an error occured and the plugin freeze.

log_error.txt

QGIS version : 3.4.6-Madeira Python : 3.7.2

i have these errors on my terminal too (dont know if it related to my first problem):

ERROR 1: TIFFAppendToStrip:Seek error at scanline 2249
ERROR 1: _tiffSeekProc:Aucun espace disponible sur le périphérique

(I have these errors more than 1000 times, so I think my raster is too large (10980 x 10980 x 4bands)

EDIT : I found an ugly but working way : I save the preview as a .tif. And I found that when I tried to do a too large preview I get a similar error : "str" object has no attribute "name"

So maybe my initial error is due to a too large file, but I rly don't understand why

Hello, please check that there is enough free space on hard disk. You can also change the temporary directory in settings https://semiautomaticclassificationmanual.readthedocs.io/en/latest/main_interface_window.html#processing

I'm closing this because of the new version 7. If you still get the same issue, please reopen it

I'm having this same issue and I can't run version 7 since I'm on a mac. I've got plenty of space on my hard drive as well. Running SCP 6.4.7, QGIS 3.10, and python 3.7.
