Hi!

I have two questions w.r.t to the attention images that are generated and available in Tensorboard. I'm training a very simple BLSTM on TIMIT with the config file provided in the recipe. At the end, I obtain 3 different pictures for the attention weights that are:

The first question is: What is this weird line happening at the beginning of the x axis?
The second one: Why three images? (names on Tensorboard are: FADG0_SI649, FADG0_SI1279 and FADG0_SI1909.

Thank you very much!
