How to use synthtext dataset to train text detection model?? When i try to make it according to docs,something i cannot understand happened.

I have found that the type of data.lmdb provided by docs or generated by tools/data/textdet/synthtext_converter is not supported by the LmdbAnnFileBackend which used in the official configs. And according to the docs, mmocr provides a new file called reg2lmbd , but it doesn't support the label with .mat file type, as synthtext has.So how can i transfer the gt.mat of synthtext dataset to the right file???That is very confusing!

[manjaro-git]

75 line filename, text = line.strip('/n').split(' ') in LmdbAnnFileBackend is the cause of error.I think the format of data.lmdb doesn't match the code.And i wanna kown what the text is ? what is the format of text?

Thanks for reporting the bug. It should have been fixed in #1159 and lmdb can be loaded with the provided config.
