Hi,

I am running a simple test for training, I have all the prerequisites installed and I am training on the default MVTec dataset with the project organized as mentioned in the readme.
This is the line of code I run to train:
python train.py -d mvtec/capsule -a mvtecCAE -b 8 -l ssim -c grayscale

It starts nicely with 10 rounds of epochs, followed by (unknowingly why) a round of 1024 epochs, where it specify a max learning rate of 0.002. At around the 30th epochs of the second round, I get the following error and the program stops:

hist_dict = dict((key, self.hist.history[key]) for key in self.hist_keys) KeyError: 'ssim'

I got the same error

I had the same error when using a Tensorflow version >=2.11. The only thing I figured out to help was to downgrade to TF 2.10.1

In case somebody needs it: I used this Docker image:

I am having the same issue working from google colab. Who else has tried this solution and did it work? How do I go about running this on google colab?
