 ## Trained model
-We provide trained model on ICDAR 2017 MLT dataset, check [here](https://drive.google.com/open?id=1kh5wXqvD1KkaSLtyEG8RUDUfSK1CHnQT) for downloading. Note that the result is slightly different from we reported in the paper, because PMTD is based on a private codebase, we reimplement inference code based on [maskrcnn-benchmark](https://github.com/facebookresearch/maskrcnn-benchmark).

 In the test stage, we use one GPU of TITANX 11G with a batch size 4. When encountering the out-of-memory (OOM) error, you may need to modify TEST.IMS_PER_BATCH in `configs/e2e_PMTD_R_50_FPN_1x_test.yaml`.
