the embeddings dimension #2

Closed Nicolabo closed 6 years ago

Hi, Thanks for your work. I found one thing in your code which is not clear for me:

embeddings = tf.Variable(tf.random_uniform([2*num_probs+2, embedding_size], -1.0, 1.0))

Why do you define 2D tensor with such shape (i.e. 2*num_probs +2)?

Thanks,
