torch::cuda::is_available() is always False in third party plugin in Adobe Premiere pro

Question

Hi, I am developing a plugin for Adobe premiere Pro. I used static lib torch in my application. However when I am trying to integrate my application to Adobe premiere pro It is reporting low-level exception error.
When I debugged for the root cause, I observed that torch::cuda::is_available() returns FALSE always. Build Environment for the application is as below.
- VS 2019
- NVIDIA GeForce RTX 3060 and CUDA Tool kit version 11.1
- Pytorch 1.8.1

I can see device_count as 1 with NVIDIA API as below in the plugin solution
result = nvmlDeviceGetCount(&device_count);

But torch::cuda::device_count() returns 0.

Could anyone help why torch is not linked to cuda in the application.

I discussed this with the PPro team's GPU specialists, who recommend you not use torch.

There have been significant stability issues, it's only performant on specific Nvidia GPU/Intel CPU combos.

Also, it's not something Adobe actively supports, or will support in the future.
