Editor crashes every time I try to play using an Internal brain type

[beardordie]

I just installed the newest ml-agents beta following the newest installation guides today, 06/25/2018. I had v0.2 beta working fine on another machine, so I know roughly how it's supposed to behave. What I am experiencing now is that all example scenes work fine on Player type brain and Heuristic type brain, but any time I set it to Internal type brain and use the provided bytes file for each example, the Unity Editor crashes upon pressing Play. I am new to crashes, so I'm not sure how to troubleshoot. I've attached the Editor log but I don't know how to read it for relevant information. I'm using Unity 2018.1.2f1
Editor.log

@beardordie Did you follow the new documentation guide? Do you have the new TensorflowSharp plugin? Have you installed the new python packages?

Also can you list out your detailed steps that leads to a crash?

I'm having the same issue, the demo scenes work with player, heuristic and external but crash when internal is used. I'm using Unity 2018.1.6f1 and Anaconda. Editor.log, video

@Setmaster Thanks for the video and log, but this information is not enough for us to help you. Please tell us the detailed steps to reproduce your error, specify things like what os you are using, which installation guide did you follow etc.

@xiaomaogy
Win 10
Version 1803
Build 17134.112
Followed this repo's installation guide, choosing to use Anaconda and after that followed the basic guide and setup the project as it was instructed.

Some issues I had but solved:

Running learn.py ModuleNotFoundError:No module named 'docopt' - Solved it by wiriting (ml-agents) C:\Users\vi7or\Documents\Repositories\ml-agents\python>python ./learn.py --run-id=run01 --train

Then I had an issue with tensorflow - Solved by installing tensorflow using conda instead of pip

Did you use py instead of python before?

Also after you click the play button in the editor, does the play button just get stuck there like that forever? Have you made sure you are using Tensorflow 1.7.1 in your python environment, and used the latest version of TensorFlowSharp plugin in the basic guide?

[Setmaster]

I don't remember trying py before and I'm not sure what you mean by stuck, a few seconds after pressing play the editor will crash. Here is a list of installed packages which includes the correct version of Tensorflow. I downloaded the package again from here ,and Unity says there is nothing new to import, also I downloaded the package and installed it yesterday so I believe I'm using the latest version.

[beardordie]

Yes I followed the newest guide. Yes I had the tensorsharp plug-in imported. yes I had all proper versions of packages as listed in the documentation requirements file, and I tried multiple versions of tensorflow, all cpu versions, and I tried with anaconda as well as without. I think my processor must not be compatible with tensorflow. Intel core 2 extreme. But that being said, does Python and tensorflow actually need to be installed on the machine just to run already-trained models from bytes files?

@beardordie No it doesn't require the python and tensorflow to be installed. But we haven't tested on the cpu you have.

@Setmaster This is something I've never seen, I've tested our repo with the Windows 10 with Unity 2018.1, and the Internal Brain works without any crash.

Can you guys build the Unity executable with the Internal Brain checked, then run the built executable in the command line and see what happens? Without any error message I am not able to even guess what's going on wrong here.....

[Setmaster]

@xiaomaogy By executable do you mean player? About the cmd, what parameter would be used for this? Also, I built a player with the brain set to internal anyway, and it crashed when executed. Here is a copy of the player if it's useful.

Hi @Setmaster, By executable I mean the stuff you've provided here.

I've tried to run your built executable provided above on my windows machine (Win 10), and it works without any crash. To this point I'm pretty sure it is a machine specific things. @beardordie Does this built executable work on your computer?

@Setmaster Is there any thing special about your computer? Have you tried this on any other computer?

[Setmaster]

@xiaomaogy I don't think so, here are some specs:
CPU: Intel Core i7 Extreme 980X @ 3.33GHz
Motherboard: ASUSTeK Computer INC. Rampage III Extreme (LGA1366)
SSD: Samsung SSD 850 PRO
Graphics: GTX 1080 EVGA

I ran it on another computer without issues.

@Setmaster You ran it on another computer and it works? So what's the difference between that computer vs your own computer?
