UnityTimeOutException

[iandanforth]

System: Windows 10 Python: 3.6.5 ObstacleTower: v1.1

When I run env = ObstacleTowerEnv('./ObstacleTower/obstacletower', retro=False) after installing the requirements I see the following:

The unity splash-screen is displayed, then a tan background appears with the main character briefly in view. She then falls off the screen leaving only the tan background.

Traceback:

Neeever mind. This is what happens when you try to run v1.1 of the exe with an old version of the env. Everybody else, don't do that.

Have same issue on Win10. What solution you find? I download v1.0(!) zip with exe-file, install v1.1 libary(and examples), and then this working(with change only dirname with executable file). With v1.1 win zip (i checked md5 sum, all correct) i have trouble :/

AND funny moment: my computer shutdown ( D: ) after i manually run .exe file w/o python wrappers. It's a joke, or why we have file named UnityCrashHandler32 xD ?) @awjuliani

UPD: shutdown only on 1.1 version, 1.0 is working, i can play and pass the levels.

@stalkermustang Hey I had to re-install this repository. So if you have a local clone

git pull pip install -e .

[stalkermustang]

Do you download v1.1 executable game file? Can you play it?

[aole]

Can't get it to work, Did you do anything else? I am able to play the game and the repository is also uptodate. @awjuliani

Sorry all that's all I had to make it work. I am able to launch v1.1 by double clicking the exe. The first time I did this I got a Windows prompt that this was unverified code and I had to click through that warning.
