@sherlockedlee Hi，I want to use my own dataset, and I modified some tips, first format the data in the same format as coco, change the input size and output size, change the self._cat_ids in the ./db/coco.py, and anywhere else should I change? thanks

from centernet.

@wudi00 You should modify the "categories" in centernet-52/104.json and detection.py in line 8.

@sherlockedlee Thankes. I have already modified the two points,

1. And anywhere else?
   2.What does the files in ./cache/coco_trainval2014.pkl mean? Does it need to be modified?

from centernet.

@wudi00 1.I can't remember clearly.All work seems to be done.
2.It's your annotations,you can't modify pickle files.You can use following code to check these files.

# -*- coding: UTF8 -*-
f = open('./CenterNet/cache/coco_train2014.pkl','rb')
data = pickle.load(f)
print(data)
