Need help solving error: "ValueError: train_pb2.load_all_detection_checkpoint_vars unsupported in TF2"

Hello. I am having problems with training the NN. I am using Tensorflow 2.4 and I am running the training from the model_main_tf2.py file.
Everything seems to be working fine up until the end when the error pops up:
" ValueError: train_pb2.load_all_detection_checkpoint_vars unsupported in TF2 "
(The full output can be seen below)

I am not sure what causes it or how to fix it so could anyone please give me a hand?
Thank you in advance,
JFPetri
