error when resuming training icdar2015

[eyebies]

Firstly, Thanks for sharing the code.
2. Train with ICDAR15
I am trying to resume training on icdar2015 and I run into the following issue
text-detection-fots.pytorch/datasets.py", line 93, in transform
intersected_quad -= crop_point
ValueError: operands could not be broadcast together with shapes (0,) (2,) (0,)
Some of the quads seem to be empty. Could I ignore those and continue. May I ask if how you fixed it? Or am I missing anything
I modified the dataset to icdar, and followed your other instructions!
thanks!

Hi, @eyebies.
intersected_quad is not supposed to be empty because of for quad_id, quad in enumerate(quads). The loop iterates over the first dimension of quads array, so quad must have something, it can't be an empty array.

I think there are two possible reasons:

1. shapely.geometry.Polygon.intersection() does something that corrupts intersected_polygon, but leaves it of type Polygon. I tried running training, and it works (Shapely==1.6.4.post2).
2. You have modified datasets.py. Originally intersected_quad -= crop_point is at line 92, but for you the line is 93. May be the change is lethal for the script :)

Hi，I got the same error, too. And I try to change the version of Shapely to Shapely==1.6.4.post2, which is same as the author's. Then it works.
