I have been using the Audio2Face app on Omniverse and it is working smoothly, except for one issue. I get the error message “Failed to build TensorRT engine” when I try to animate the face model with an audio track. The face model loads fine, but there is no movement when the audio plays.
System:
RTX 3050 laptop gpu
16GB RAM
Audio2Face 2023.1.1
@pingligamers2828 if you could provide your latest Audio2Face log file, that’d be great. the log file can be found here:
C:\Users\<USER>\.nvidia-omniverse\logs\Kit\Audio2Face (2023.1 subfolder)~/.nvidia-omniverse/logs/Kit/Audio2Facein the meantime, can you check to see if you are using the recommended version of graphics driver specified on this page?

i am sure the dev would appreciate the upload! as a layman, it may be related to VRAM bottleneck happening:

but i’ll have to do some more digging to see whether there are other reasons that could’ve caused this. in the interim, here’s a breakdown of the recommended spec for both mobile and desktop workstation. some of the examples in A2F would require 5GB+ of VRAM from the getgo, so i could see the challenges you are experiencing on a 3050 laptop GPU.
Hi @pingligamers2828 You seem to have 2 GPUs. Could you please disable the 2nd one from Device Manager and try again?
I disabled the second GPU through Device Manager and tried again, but my issue still persists.

Thank you, @Simplychenable , for helping me.
Oh it seems you don’t have enough VRAM:
