lmdb.CorruptedError #113

Open nischal-sanil opened 4 years ago

Hello,

I was trying to train the ST_spe dataset from here using the following command:

!CUDA_VISIBLE_DEVICES=0 python3 /content/deep-text-recognition-benchmark/train.py \
--train_data /data_lmdb_release/training \
--valid_data/data_lmdb_release/validation \
--select_data MJ-ST_spe --batch_ratio 0.5-0.5 \
--Transformation TPS --FeatureExtraction ResNet --SequenceModeling BiLSTM --Prediction Attn

Got an Error as shown:

Filtering the images containing characters which are not in opt.character
Filtering the images whose label is longer than opt.batch_max_length
--------------------------------------------------------------------------------
dataset_root: /content/drive/My Drive/FYLE/text identification/data_lmdb_release/training
opt.select_data: ['MJ', 'ST_spe']
opt.batch_ratio: ['0.5', '0.5']

    train_dataset = Batch_Balanced_Dataset(opt)

    _dataset = hierarchical_dataset(root=opt.train_data, opt=opt, select_data=[selected_d])

    dataset = LmdbDataset(dirpath, opt)

    label = txn.get(label_key).decode('utf-8')
lmdb.CorruptedError: mdb_get: MDB_CORRUPTED: Located page was wrong type

Can anyone explain what the issue is and how do I correct it?

Also, Is there a pre-trained model that was trained on the ST_spe dataset?

Thanks,

I met the same problem. Have you solved it up to now?
