I have arranged the data as required and split it into train and validation sets.
Like:

train(340+ sequences):

        -data_root
             -images
                 -00000.jpg
                 -00001.jpg
               .........

              -landmarks-dlib68
                 -00000.json
                 -00001.json
                ........

val(101 sequences):

         -data_root
             -images
               -00000.jpg
               -00001.jpg
               .........

             -landmarks-dlib68
               -00000.json
               -00001.json
               .....

Used:

python scripts/build_lmdb.py --config configs/projects/fs_vid2vid/my_dataset/ampO1.yaml --data_root data_root/ --output_root datasets/my_dataset/lmdb/[train | val] --paired

This made files in the structure:

           -train
                 -all_filenames.json
                 -metadata.json
                 -images
                         -data.mdb
                         -lock.mdb
                 -landmarks-dlib68
                         -data.mdb
                         -lock.mdb

Changed the config file's input LMDB path train to: datasets/my_dataset/lmdb/train and val to datasets/my_dataset/lmdb/val

But, after I run the training command I get:

So, what is causing this error? Any help will be appreciated.

@Quanta-of-solitude Did you solve the issue?

yes, instead of lmdb I used the filenames directly
