Raster stack of bands do not get created on macosx #187

Closed kaarigar closed 9 months ago

kaarigar commented 2 years ago

I am using Landsat 8 bands to create virtual raster and stacked bands. However, only the virtual raster gets created - the band stack geotiff doesn't get created. I am using QGIS Hannover LTR 3.16.11

Hello, I think it is an installation issue (maybe related to this https://github.com/semiautomaticgit/SemiAutomaticClassificationPlugin/issues/144).

Please copy the log file following these steps https://semiautomaticclassificationmanual.readthedocs.io/en/latest/faq.html#how-can-i-report-an-error

Hello @semiautomaticgit

Maybe is not related to #144

Hello @jsparedes , it seems an installation issue. You can try to follow this guide https://semiautomaticclassificationmanual.readthedocs.io/en/latest/faq.html#i-have-installation-issues-on-mac-os-how-can-i-install-scp-on-mac-os

I'm closing this because of the new version 8 of SCP. Please reopen it if it is still relevant in the new version. Thank you!
