Generate extreme point annotation from segmentation

[keravraj20]

@xingyizhou while running python gen_coco_extreme_points.py for generating extreme points, I get this error. I tried looking at the exact column where it shows error, but it seams right.

Error I get:
Traceback (most recent call last):
File "gen_coco_extreme_points.py", line 80, in
data = json.load(open(ANN_PATH.format(split), 'r'))
File "/usr/lib/python3.6/json/init.py", line 299, in load

obj, end = self.scan_once(s, idx)
json.decoder.JSONDecodeError: Expecting ',' delimiter: line 1 column 54525953 (char 54525952)

Can you pls help me with this?
