WebMay 31, 2024 · with tf.Session () as sess: # Loop until all elements have been consumed. try: while True: r = sess.run (images) except tf.errors.OutOfRangeError: pass. I get the warning. Use `for ... in dataset:` to iterate over a dataset. If using `tf.estimator`, return the `Dataset` object directly from your input function. Webso it means prefetch could be put by any command and it works on the previous command. So far I have noticed the biggest performance gains by putting it only at the very end. There is one more discussion on Meaning of buffer_size in Dataset.map , Dataset.prefetch and Dataset.shuffle where mrry explains a bit more about the prefetch and buffer.
