Hi @ElyMatos
I just wanted to mention that I added two new tutorials to our documentation (New Tutorials on Using Monty in Custom Applications) One of them talks through the Omniglot example in detail and also provides code to follow along.
As I was writing it I actually noticed that the OmniglotEnvironment code was broken and added a fix. Maybe give it a try again now! Let me know if you run into any issues.
