Description

Hi, I am trying to follow this tutorial: https://github.com/google/trax/blob/master/trax/examples/NMT_with_Transformers_Reformers_using_Trax.ipynb Setting the runtime to TPU on Colab used to work couple of days ago. But now it crashes with error:

TypeError: float() argument must be a string or a number, not 'jaxlib.tpu_client_extension.PyTpuBuffer'

This happens at this step: training_loop = training.Loop(model,.....
