What is the relationship between steps and epochs in TensorFlow?

Question

I am going through TensorFlow get started tutorial. In the tf.contrib.learn example, these are two lines of code:

input_fn = tf.contrib.learn.io         


        

Answer 1

num_epochs: the maximum number of epochs (seeing each data point).

steps: the number of updates (of parameters).

You can update multiple times in an epoch when the batch size is smaller than the number of training data.
