finetuning notebook runtime error

[sp7412]

I just clicked on the "open in colab" link (https://colab.research.google.com/github/google-research/simclr/blob/master/colabs/finetuning.ipynb)

I made no changes to the notebook. My runtime type is set to GPU

I clicked Runtime-> Run all but I get this error:

`INFO:tensorflow:Saver not created because there are no variables in the graph to restore INFO:tensorflow:Saver not created because there are no variables in the graph to restore

You probably have run it before. So use "Restart and run all" instead?
