No response from the bot - AttributeError: __enter__

Operating system: Windows Server 2012 R2 Standard

Hi,
I tried to train the bot for few stories and get a 'hi' (greet) response from it.
There is no response from the bot when I try to communicate via terminal.
Below is the behavior. Once I enter 'hi' and hit enter, I get the following error.

Bot loaded. Type a message and press enter (use '/stop' to exit):
hi

Yes, I'm also facing the same issue. Please could you look into this.

In most other cases you should consider using 'safe_load(stream)'
data = yaml.load(stream)
