<Product Name> incompatible with mlagents-learn

[TiNovTec]

Describe the bug
The Unity Editor -> Project Settings -> Product Name: "Unity Environment" is incompatible with mlagents-learn with build apps. ( for example mlagents-learn config/trainer_config.yaml --env=BuildFolder/Unity Environment.exe --run-id=RunIdentifier --train ).

The learning simply doesn't start without any warning or error message!

The Product Name should be "UnityEnvironment" instead of "Unity Environment".

To Reproduce
Steps to reproduce the behavior:

1. Use any example and try to train it with a build app and the default demo settings.

Console logs / stack traces
none

Environment (please complete the following information):

• OS: Windows 10
• ML-Agents version: latest develop

Hi @TiNovTec -- we regularly train builds with that product name, so I think it's unlikely that is what's causing the issue. Does anything at all come up in the console after you enter your command?

One issue I see as a potential problem is that your .exe file is two words. You may need to escape the space in your path to BuildFolder/Unity\ Environment.exe

[TiNovTec]

Yes, @harperj. It's the white space. And no, escaping doesn't work and wouldn't be user-friendly at all. So please just change the name to contain no white space! xD

Here is what I see.

Hi @TiNovTec, request noted to share with the team. In the meantime you can create your build with a different name (without the space) or escape the space in a different way. I think my suggestion of the forward slash was incorrect, on Windows I believe you can escape with ^.

This was fixed in our examples in #3612. Closing this.
