Prerequisite

• I have searched Issues and Discussions but cannot get the expected help.
• The bug has not been fixed in the latest version(https://github.com/open-mmlab/mmengine).

_base_ = f'{mmyolo_configs}/yolov5/yolov5_s-v61_syncbn_fast_1xb4-300e_balloon.py'

test.py

from mmengine.config import Config

if __name__ == '__main__':
    cfg = Config.fromfile('./test_config.py')
    print(cfg)

Additional information

openmmlab 1.0 mmcv.config.Config.fromfile() is work, so i think there is something wrong in the added code

but i can't solve it
