imageClassifier error : GetBlockRef failed at X block offset ....., Y block offset .... what causes this and how to get rid of it?

Just did the following with your data and package OTB-6.6.0-win64:

otbcli_BandMath.bat -out black.tif -il "ROI final 1.13.tif" -exp "im1b1"

Works like a charm …

Do you have those logs somewhere ? I would like to see the partitioning you have.

Yes most of the commands works well but not the imageClassifier sadly.

Yep :
otbcli_BandMath.bat -out black.tif -il “ROI final 1.13.tif” -exp “im1b1”

Ok, i am running classification on two different systems to check, right now.

I’ll keep you posted.

ty very much. I obtained a classification by compartimentating the ROI so i can now continue my work but it would be interesting to know what happened.

Windows run is at 68%, no problem so far.

Linux run was almost 90% without any issue, but got killed by admin because it was heavily using a shared node on our infrastructure.

Both processes completed without error.

What’s the problem then… is my processor burning ?

I have no idea, but I doubt this comes from a lack of processing power … This error comes from gdal read operations and usually means that the tiff file is corrupted.

but my image was normal wasn’t it ?
If it is corrupted why does it work with you but not on my pc
