AssertionError in training about crowddet HOT 8 OPEN

Try several times, sometimes this error raises at the beginning of training.

Try several times, sometimes this error raises at the beginning of training.

Sorry, but we've tried several times and just get the same error in the almost same iteration in the first epoch

from crowddet.

Have you modified the code or data? Such mistakes rarely occur.
Try changing the dataset initialization sequence or decreasing the learning rate.

I have a another AssertionError in training.
Can you help me?

Looks like the annotation file path is wrong, Check the "train_source" and "eval_source" in config.py.

你好，请问你的问题解决了吗，我好像也遇到了类似的问题，关于load_json_lines的问题，找不到json_file的路径

检查一下文件到底在不在那个路径就可以了。

嗯嗯，我是在运行这行代码时：python3 eval_json.py -f your_json_path.json
遇到了以下错误：
Traceback (most recent call last):
File "eval_json.py", line 36, in
run_eval()
File "eval_json.py", line 33, in run_eval
eval_all(args)

res_line, JI = compute_JI.evaluation_all(args.json_file, 'box')

records = misc_utils.load_json_lines(path)
File "../lib/utils/misc_utils.py", line 11, in load_json_lines
assert os.path.exists(fpath)
AssertionError
谢谢您。我不清楚your_json_path.json是什么，所以也找不到它的位置，但是打开result_eval.md后，里面有一行your_json_path.json，但我还是不知道怎么修复这个错误，或许您有什么意见吗？
