Ml-agents: UnityEnvironmentException: Couldn't launch the 3DBall environment. Provided filename does not match any environments.

Hi
I tried the 3DBall Tutorial. But when I try to load the environment I get the error:

I use Unity to Build the exe file named"3DBall".And Copy this flie to python folder.But it's show error.
on the Tutorial step:

I think the "environment" is "3DBall.exe" flie and "3DBall_Data" folder. Copy this two flie to python folder.
What is error on my step?

I am using Windows 10. other environment like the Tutorial say

Hello,
I tried only on MAC. On it i have to save build in unity-environment folder, and next in the Jupyter notebook change env_name = "name_of_the_file" in Basics.ipynb.

Hi @Izhmael
Thanks! I try on your step. But still error

I don't think I know how to use the jupyter. I'll learn how to use the jupyter, first

Hi @shengtianzhu,

It seems that you are running one ipython notebook from another. Is there a reason for this?

[Fangh]

you have to put your build name 3DBall.exe in python directory. (my env_name = "build" because my game is named build.exe) :

Hi @Fangh
this is my python directory screenshot

and my Basics.ipynb screenshot is

Hi @awjuliani
I run this ipython notebook like this.In Jupyter Home view. Click the Python3 button jump to the Untitled1 page. In the Untitled1 page, I run this command
“%run C:/Users/Sheng/Downloads/ml-agents-master/python/Basics.ipynb”。The python directory screenshot and Basics.ipynb screenshot in the above reply
All the steps are shown in the screenshot

Hi @shengtianzhu,

I believe the issue is that you need to launch jupyter notebook itself from your ml-agents/python directory. It seems that it is being launched from another directory, whichever one contains the two Untitled notebooks.

Had some trouble with this in OSX Sierra. Fix for me was:

• as awjuliani says, run notebook from ml-agents/python dir
• put your Foo.app unity build in that same ml-agents/python dir
• now if you run e.g. Basics in notebook then set env_name = "Foo"

i have the same problem and tried as @jglazman said, but that didn't help(
I am using Unity 2017.3.0f3 Personal and macOS High Sierra 10.13.2
I Installed tensorflow cpu through anaconda.
Terminal:

Folder ml-agents/python:

Jupyter:

@tananuka it looks like your app file is named Foo, but it should be named Foo.app

ml-agents/python/Foo.app

[tananuka]

@jeremyPLR
It named, just filename extension hided

[tananuka]

Thanks to @wouterhardeman. When i opened the application (Foo.app) by right-clicking and selecting 'Show Package Contents' and then go to 'Contents/MacOS', the file is called 'test2'. I renamed it from "Foo" to "test2" and env_name="test2". That helped because it is first name of build. 'Ball3DAcademy' started successfully!
All glory to @wouterhardeman 👍

[awjuliani]

Glad you were able to figure out the problem @tananuka! OSX is somewhat tricky in that changing the name of the .app does not change the name of the actual binary file itself. Our UnityEnv code currently assumes that the name of the .app and the name of the binary are the same. Now that I think about it though, this doesn't necessarily need to be the case... I will add to our to-do list making this more flexible.

[awjuliani]

Thanks to @wouterhardeman, the renaming .app issue has been fixed! https://github.com/Unity-Technologies/ml-agents/commit/a2f8ef564471cef99fde5b594daf1368a50d9b95

In windows 10 you give your application.exe path

For example "E:\ml-agents-masterenvs\MLFirst\Sample Project\"
