Colab: FileNotFoundError: File b'tpu_train/metadata/results.csv' does not exist

The stock Google Colab link in the README.md isn’t working correctly. I added a line to download the titanic.csv, then hit run all. Full stack trace below:

I have created a StackOverflow question [https://stackoverflow.com/q/55959256/1330974] related to this issue. If anyone finds a solution to this, please share. Thank you!

I tried adding %tensorflow_version 1.x in the colab document but now i get a different error. Now i get and Index Error for the line: train_results = results.tail(1).to_dict('records')[0] My guess is that tensorflow.train.cosine_decay does not exist in the current version of tensorflow. EDIT: Just changed from TPU and still added the tensorflow version and its working!
