      You now can train a really good image classification model on 25k images in less than 2 hours, entirely for free, on a Colab GPU. And it's dead easy. What a time to be alive I remember when you had to write your own CUDA and C++ and you needed a hardware budget

      This notebook’s data augmentation portion seemed to stop working on 2.3.0-dev20200624. Specifically, there’s a cell that visualize 9 random augmentation, they look all the same to me, I hope this isn’t broken. This was working a few weeks ago.

      Thanks. Would you happen to know the last build/label where the Keras layer data augmentation still work?

          I thought i tried TF 2.2.0 (the default from Colab right now), and it didn’t work. I will double check.

          I found smthg perplexing about using my own http://tf.data .Dataset pipeline, but the rest pretty much the same as your notebook (on binary classification). I posted this Q and its resolution:https://stackoverflow.com/questions/62585490/as-list-is-not-defined-on-an-unknown-tensorshape-on-y-t-rank-leny-t-shape-a …

          Thanks. I used “%pip install tf-nightly==2.3.0.dev20200620”, and it seems to be the last good build for this issue.
