Environment Executable don't work in Azure VM

Unity Engine

I tried using Environment Executable for training on local Windows and Linux, and it worked really great.
But when I follow the same process in Azure VM, the Environment Executable(the game) just quit immediately, and ml-agents cannot connect with the Environment Executable.

I also tried two methods to build the Environment Executable, one is directly build in Azure VM ,and the other is build in host computer, then transfer the Environment Executable to Azure VM. Both methods failed the same way as before.

Is there any workaround here?

Are there any logs from the executable? Can you try running it directly (without mlagents-learn) and pass “-logFile -”, or pass “–env-args -logFile -” to mlagents-learn? That should print the logs to the console.

If you can’t run the executable outside of mlagents-learn, there’s not much we can do to help in this forum…

Thanks for reply.
Follow your steps, I got this one below.
I think the problem isn’t the ml-agents…does this mean I don’t have openGL?
If so, that’s weird, I did install it…
I will try reinstall it.

Sorry, I’m not sure the best way to solve this. There’s a similar problem described here Linux Server : Unable to find a supported OpenGL core profile · Issue #1464 · Unity-Technologies/ml-agents · GitHub

If you don’t use visual observations, you should be able to add “-batchmode -nographics” to the Unity commandline (or equivalently, “–no-graphics” to the mlagents-learn commandline) to hopefully bypass this.

Thanks for your reply. I will give it a try next Monday.

I solve the problem by using the instruction given here.
And also, I have to export the Environment Executable in headless mode.
Thanks for your help.
