Execution

Chapter Goals:

• Iterate through a dataset and extract pixel data using tf.compat.v1.Session

A. Data iteration

In the previous chapter we set up a next-element tensor using the get_next function. The way we actually execute the data extraction is by using the run function of tf.compat.v1.Session.

Each time we use sess.run(next_image), we are iterating a single step through our dataset. So the first time we use sess.run(next_image), it’ll return the first pixel array in dataset (as a NumPy array), and the $i^{th}$ ...
