Training stops before epoch 0 after loading best.torch

[cvKDean]

Good day,

I am trying to train on my own dataset as with the case with issue #215. I opted to load the weights from the crowdAI dataset trained model and then continue training on my own images from there.

Using issue #160 as reference, I loaded the weights from best.torch.
(btw, is it correct to use self.load('.../experiments/mapping_challenge_baseline/checkpoints/unet/best.torch')?)
I also set self._initializar _model_weights = None'.

However it threw out an error: ‘module’ object has no attribute ‘_rebuild_tensor_v2’
Which I was able to fix via this thread.

Another error occurred:
And I fixed it via this thread.

Now, running python main.py train --pipeline_name unet_weighted does not throw any more errors, but training seems to not start at all (no prints of epoch 0).
Here is the full printout of the console:

No errors are reported but the training does not seem to start. Do you have any ideas for why this is the case? Thank you.

Hi,
I encountered the same issue.
"python main.py train --pipeline_name unet" works fine, but "unet_weighted" does not start training.

Have you found a fix?

[data-overload]

I'm also trying to train my images on either of the contest weights (unet or scoring_model) but I'm not sure how to load those weights such that the training continues on them.

@zeciro running that command with either unet or unet_weighted gives basically the same console output as the OP shows (no errors, but no output seems to be produced).
