AttributeError: module 'labelme.utils' has no attribute 'draw_label',labelme_json_to_dataset批量处理json

Error type: AttributeError: module 'labelme.utils' has no attribute 'draw_label'

Reason for the error: It is caused by labelme using labelme_json_to_dataset to batch process json file versions that do not meet the requirements.

solution

Uninstall labelme and install the specified version

pip install labelme==3.16.2

Then find the json_to_dataset.py file in the environment:

open it and replace the following code:
