NotFoundError: Key Variable not found in checkpoint [[{{node save/RestoreV2}}]] (Not able to retrain from checkpoint provided in IROS18)

[Prakadeeswaran05]

Hey! while trying to retrain(followed the training steps in the readme) using the checkpoint provided inside IROS18 I faced this error! NotFoundError: Key Variable not found in checkpoint [[{{node save/RestoreV2}}]] What could be the reason for this error? Can we only train from scratch?

I look forward to your response!

Hi @Prakadeeswaran05
that's weird, the weights should be compatible with monodepth training scripts.
You can have a look here to selectively restore only a portion of the variables from the checkpoint:

let me know if this works for you ;)
