Thank you for trying out Audio2Face. Will take a look at the log and see what the issue might be. In the meantime do you mind giving us the following information?

  • Windows version (go to windows menu and type “winver” and take a screenshot of the window that would popup
  • The GPU you are using and the driver version


AWS EC2 g4dn.4xlarge
Windows 2019 Server

Great, thanks for the information.

T4 Gpu is fine. But the Windows version is the problem. We don’t support windows version before version 1909. I think the version you have is 1809. The load issue most likely came from that.

Some more info here also.

@siyuen It possible to know which dll is missing or having issue?
