DATASET.DATA_EXT = "bin"

Not able to create the binary file. I have kept 18 HR images in 'rcan-it/ptsr/datasets/SR/BIX2X3X4/DF2K/DF2K_train_HR/' folder and their corresponding LR images in 'rcan-it/ptsr/datasets/SR/BIX2X3X4/DF2K/DF2K_train_LR_bicubic/X2' folder. But the error is shown below:
`Total number of parameters: 15444667
Using Dataset(s): DF2K for training

/content/drive/MyDrive/rcan-it/ptsr/datasets/SR/BIX2X3X4/DF2K/bin/train_bin_HR.pt does not exist. Now making binary...
