Evaluate Only Image(s) #253

Thank you for your contribution!

By the way I have question, how do I inference an image and dump the bbox & mask information to file? I don't have any json file whatsoever related to those images, image only.

Thanks!

244 Please see this reference it will help @mdtjan

Great! Thanks for your help. @dbolya

By the way, I'm trying to follow #244 and #230

So here's what I tried:

  1. error (1) when set has_gt in config.py into False, so it must be True(?)
  2. create notation for image in COCO format, but with empty List for annotations. Still have error (1).
  3. input [[0,0]], 0, [0,0,0,0] for "segmentation", "area", and "bbox" respectively in annotations. Still error (2).

Error (1) Traceback (most recent call last): File "eval.py", line 1079, in evaluate(net, dataset) File "eval.py", line 909, in evaluate img, gt, gt_masks, h, w, num_crowd = dataset.pull_item(image_idx) File "/home/martin/yolact/data/coco.py", line 173, in pull_item if target.shape[0] == 0: AttributeError: 'NoneType' object has no attribute 'shape'

Do you have any idea how to solve it?

I also tried to follow coco2017_testdev_dataset definition and all in #230

All I got is Error (1). I'm positive about that.
