I'm trying to understand the structure and the coding of tensorflow. While going through this tutorial "https://danijar.com/introduction-to-recurrent-networks-in-tensorflow/" I have searched for the code that is used in the functions.
For example the line
cell = GRUCell(num_neurons) # Or LSTMCell(num_neurons)
output, state = tf.nn.dynamic_rnn(cell, data, dtype=tf.float32)
You can find it and other related operations here: https://github.com/tensorflow/tensorflow/blob/master/tensorflow/python/ops/rnn.py
