Data provider min() error if no images #45

Open will-moore opened 6 years ago

will-moore commented 6 years ago

For example, select an empty Orphaned Dataset and "Add Table Data..." > "ROI_count"

Since the img_ids list is empty, we get empty values list in numpy.amin(values) which fails.

Nightshade error reported with URL /parade/data/Uk9JX2NvdW50/ (ROI_count) with no query string for e.g. ?dataset=1, which gives us an empty img_ids list. Don't know how this occurred in the UI.
