train.py problem

[subetter]

Hello, Thank you for your contributions! But when I run the train.py, my console report this problem:
[libprotobuf ERROR external/com_google_protobuf/src/google/protobuf/text_format.cc:337] Error parsing text-format tensorflow.data.experimental.DistributedSnapshotMetadata: 1:1: Invalid control characters encountered in text.
[libprotobuf ERROR external/com_google_protobuf/src/google/protobuf/text_format.cc:337] Error parsing text-format tensorflow.data.experimental.DistributedSnapshotMetadata: 1:3: Expected identifier, got: 8756226735025337253

I tried to change the version of protobuf but nothing worked.

and I add 'os.environ['TF_DISABLE_MKL'] = '1'
os.environ['TF_ENABLE_ONEDNN_OPTS'] = '0'' in my code but GPU doesn't work, which resulting in long training sessions. can you help me？many thanks.
