Hi, I’ve tried to run TensorFlow_Audiobooks_Machine_learning_Homework, but I’ve gotten the following error message (I’m using Python 2 and Tensorflow 1.4.0): TypeErrorTraceback (most recent call last) <ipython-input-2-c3f67ecae46a> in <module>() 72 # As a reminder, it batches samples together, one-hot encodes the targets, and returns 73 # inputs and targets batch by batch ---> 74 for input_batch, target_batch in train_data: 75 _, batch_loss = sess.run([optimize, mean_loss], 76 feed_dict={inputs: input_batch, targets: target_batch}) TypeError: instance has no next() method The first cell of this code run without errors. How could I solve the problem? Thanks a lot, Ligia Batista

Hi Ligia, The error states 'instance has no next() method'. The point is that in Python 2 and Python 3, classes and methods are defined in different ways. You can read more about that here: https://portingguide.readthedocs.io/en/latest/classes.html If I remember correctly, to make it work, you needed to place double underscore before and after a method. So when you define def next() you should write: def __next__() instead. Iliya
