Just some questions

Hello, first of all, congrats for the article.
I'm using it for study, and i'm trying to run your code to better undestanding.
So, i have some questions:

• Do you remember the exact versions of tensorflow, keras and gym used?
• I tried with tensorflow 1.15 and keras 2.3.1 and i'm getting the following error, do you what am i doing wrong?:
  tensorflow.python.framework.errors_impl.FailedPreconditionError: Error while reading resource variable dense_3/kernel from Container: localhost. This could mean that the variable was uninitialized. Not found: Container localhost does not exist. (Could not find resource: localhost/dense_3/kernel)
