Train with lmdb dataset

[CuongNN218]

I want to train Master with LMDB dataset but I don't see any args related to image size. How can I train with fixed image size ?

@wenwenyu and how can I train with only one GPU

[wenwenyu]

Hi, LmdbDataset has added img_w and img_h args. Training with one GPU can use debug model. e.g. python train.py -c configs/config.json -d 1 -dist false, and -d specify which one gpu will be used.

how can I create a lmdb dataset to work with it. Maybe your key in lmdb file is quite different from that of deep-text-recognition-benchmark @wenwenyu

[wenwenyu]

Yes, the key in the lmdb file is different from that of deep-text-recognition-benchmark. Two ways to deal with this difference.

• You can modify the key to adapt your lmdb dataset, including nSamples, image_key, and label_key

• Refer to the example of creating lmdb dataset to satisfy our LmdbDataset
