mlagents-learn and Windows Server 2019 Errors

Good day, I have been successful installing ML Agents on Windows 10 machines but now I am having a problem installing this on Windows Server 2019

The install mimics my Win 10 versions with Python 3.6

There are no installation errors and the Unity EXE runs fine on the server.

When I call the mlagents-learn or tensorboard I get a slew of errors.

This is from the mlagents-learn log.

Any thoughts about how I can resolve this one?

So, I believe it's due to AVX instruction not supported on the Server CPU

The server uses a set of Intel(R) Xeon(R) CPU X5650 @ 2.67GHz

Too bad, it would have freed up my main machine... dang it!

 

Its the AVX instruction.. I think earlier versions were not compiled with AVX but newer ones are and i need 2.2.0 for MLAgents

 

I tried but it said it required 2.2.0.. ??

 

1.5 was the last version complied without AVX.. So it wont support.

 

thanks, i have a few machines around here. thanks for the details @ervteng_unity
