Evaluation and Test in my own dataset - json.decoder.JSONDecodeError

[Vania-Guima]

For text detection task, I used your pretrained model MobileNetV3_large_x0_5_pretrained with det_mv3_db.yml configuration to test and evaluate in my own dataset. The results of the inference were unacceptable.

When I tried evaluate the test dataset I get the following error:
(...) ppocr\data\imaug\label_ops.py", line 51, in call
label = json.loads(label)
(...)
json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line 1 column 3 (char 2)

Someone can help me?
