TPU support for image augmentation with transforms
I recently re-coded my input image pipeline using tf functions and tf records so that I could use TPUs (was previously using a custom tf.py_function with opencv). The problem is that I used tfa.image.transform to apply rotation and scaling…

Why is Google colab TPU slow?
I'm using Talos to run hyperparameter tuning of a Keras model. Running this short code on Google colab TPU is very slow. I think it has something to do with the type of data. Should I convert it to tensors to make the TPU faster?
