Hi, there is a bg in `policy_gradient_reinforce_tf2.py` at `line 39`. `loss = network.train_on_batch(states, discounted_rewards)` to fix this I made two changes, 1. one_hot_encode the actions `one_hot_encode = np.array([[1 if a==i...

Policy Gradient Issue: ValueError: Shapes (20, 1) and (20, 2) are incompatible

Hi. The code [Code](https://github.com/adventuresinML/adventures-in-ml-code/blob/master/policy_gradient_reinforce_tf2.py ) is not working with this line: `loss = network.train_on_batch(states, discounted_rewards)`.

loss = update_network(network, rewards, states, actions, num_actions) loss = network.train_on_batch(states, discounted_rewards)

Should not the model be fitted (keras.fit(...)) and predicted (keras.predict(state)) in double Q learning (and also in dueling Q learning) examples? Seems you also forget to apply the same in...

Can you please provide a tutorial on how to run tf_word2vec.py in hadoop , basically to distribute the workload and then reduce.
