When I executed
data = tfds.load("cycle_gan/monet2photo", try_gcs=True)
for i in data['trainA']:
print(type(i))
When I try this without tpu, I get images in jpg formats but with tpu I am getting tfrecords using and ended up at below error

I want to train cyclegan over the dataset using data so
Please help me how to preprocess this dataset to get images as tensors to continue?
