In the top example, the code within the for loop is actually executing the tf graph to extract examples back into python. So the stuff in read_my_file is pretty much the stuff BEFORE the tf.Session() is created. Remember that most of what you write in Python is constructing a graph, which is a sequence of ops that TensorFlow will execute. (2) It's supposed to set up a very similar set of ops, but not actually DO the reading. There's a new read op in progress that should also help make it easier, but I don't think it's included in 0.9. If you want to only read the number of examples in the files, you can catch the OutOfRangeError that gets thrown if the inputters run out of inputs, or read exactly the number of records present. So 1200 is simply the number of records the programmer has chosen to retrieve in the example. :) With the way the CSV reading example is set up, continued reads will read through the two CSV files as many times as desired (the string_input_producer holding the filenames does not have a num_epochs argument supplied, so it defaults to cycling forever). (1) 1200 is arbitrary - we should fix the example to have a named constant used there to make it more clear.
