no data_config.json

Dear @zhen-he

I got an error - seem like related to the reading of data_config.json in the line 80 of the run.py Do we suppose to generate the file of data_config.json before the line 80 or we should put into the root?

Traceback (most recent call last): File "run.py", line 85, in o.exp_config = utils.load_json('modules/exp_config.json')[o.exp] File "/home/yang/huckcode/tracking-by-animation-master/modules/utils.py", line 57, in load_json data = json.load(f) File "/opt/conda/envs/test1/lib/python3.7/json/init.py", line 296, in load parse_constant=parse_constant, object_pairs_hook=object_pairs_hook, **kw) File "/opt/conda/envs/test1/lib/python3.7/json/init.py", line 348, in loads return _default_decoder.decode(s) File "/opt/conda/envs/test1/lib/python3.7/json/decoder.py", line 337, in decode obj, end = self.raw_decode(s, idx=_w(s, 0).end()) File "/opt/conda/envs/test1/lib/python3.7/json/decoder.py", line 353, in raw_decode obj, end = self.scan_once(s, idx) json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line 9 column 1 (char 175)

Hi @huckiyang,

The data_config.json contains hyper-parameters related to the data itself, and is generated along with the data.

To generate data_config.json, you need to run gen_mnist.py or gen_sprite.py or gen_duke.py first (please see Section 3.1 of the README), where the last line utils.save_json(data_config, path.join(output_dir, 'data_config.json')) generates data_config.json.

Hi @zhen-he thanks - I did generate the data but found out there is a format error on the json file. I follow this https://github.com/StudentWong/tracking-by-animation/commit/45dc6795eabe110aa609606e2af30dd12f8db7da and the issue is resolved. Thank you again for the fast reply.
