If you are using mmocr 1.x (1.x or dev-1.x branch), just write a script and convert it to the following format:

Thanks for your answer.But i don't have old version gt file ,how to use write scipte for example(python tools/dataset_converters/textdet/data_migrator.py ${IN_PATH} ${OUT_PATH}) to get new gt file.

That script is prepared for those who want to migrate from MMOCR 0.x, which is not applicable to your case. You'll have to write a custom script and convert your annotation to the new data format.
