CelebA-HQ 256x256 Data Pre-processing

[KomputerMaster64]

Thank you team for the sharing the project resources. I am trying to process the CelebA-HQ 256x256 dataset for the DDGAN model. The DDGAN repository recommends going over the dataset preparation methods in the NVAE repository (this repository).

The following commands will download tfrecord files from GLOW and convert them to store them in an LMDB dataset.

Use the link by openai/glow for downloading the CelebA-HQ 256x256 dataset (4 Gb).
To convert/store the CelebA-HQ 256x256 dataset to/as the lmdb dataset one needs to install module called "tfrecord".
The missing module error can be rectified by simply executing the command pip install tfrecord.



!mkdir -p $DATA_DIR/celeba
%cd $DATA_DIR/celeba
!wget https://openaipublic.azureedge.net/glow-demo/data/celeba-tfr.tar
!tar -xvf celeba-tfr.tar
%cd $CODE_DIR/scripts
!pip install tfrecord
!python convert_tfrecord_to_lmdb.py --dataset=celeba --tfr_path=$DATA_DIR/celeba/celeba-tfr --lmdb_path=$DATA_DIR/celeba/celeba-lmdb --split=train

The final command !python convert_tfrecord_to_lmdb.py --dataset=celeba --tfr_path=$DATA_DIR/celeba/celeba-tfr --lmdb_path=$DATA_DIR/celeba/celeba-lmdb --split=train gives the following output:

added 27000 items to the LMDB dataset.
Traceback (most recent call last):

    main(args.dataset, args.split, args.tfr_path, args.lmdb_path)
  File "convert_tfrecord_to_lmdb.py", line 58, in main
    print('added %d items to the LMDB dataset.' % count)
lmdb.Error: mdb_txn_commit: Disk quota exceeded

I am not sure I have made the LMDB dataset properly, I request you to guide me.

@KomputerMaster64 hello, I also want to convert the CelebA-HQ 256x256 dataset to the lmdb dataset, however, there is an error message:"AttributeError: 'bytes' object has no attribute 'cpu'" when runs to code:"im = data['data'][0].cpu().numpy()", and if I remove 'cpu' to let the code be "im = data['data'][0].numpy()", it also throws an error:"AttributeError: 'bytes' object has no attribute 'numpy'", so I want to ask you how you resolved this problem? Thanks a lot !
