Error when parsing json file

When trying to run the coco-viewer I get error

INFO: Starting...
INFO: Parsing ../SKU110K_fixed/annotations/val.json...

    draw.polygon(m[0], outline=fill, fill=fill)
IndexError: list index out of range

My json file contains only bounding boxes and no masks. Looks like the coco-viewer returns error because there are no polygons defined in json file.

@jabolcni Thank you for your interest in cocoviewer! Yes, the app still sometimes is too much COCO oriented, with lots of hard coded stuff (related to #46 ). I am planning a massive update to fix this, and make it more flexible.

For now, In your case simply comment out these lines:

# Draw masks
# if masks_on:
    # draw_masks(draw, objects, names_colors, ignore, alpha)
