Just ran ImageCleaner with command
ImageCleaner(ds, idxs, path)
this is on Google Colab
and it does generate well the .csv file apparently, but it hangs and doesn’t seem to come back at all, so I have to stop it manually (the .csv is generated though)
Try setting up a local Jupyter environment, connect it to your Google Drive and run the widget there. Take the generated .csv file and go back to Google Colab to complete Lesson 2. Found this workaround here: Image cleaner widget breaks google colaboratory?
