'TensorRT not found' after switching from TD v2023 to v2025 and installing Nvidia AR Version 0.8.7

Hey TD community,

Recently I decided to upgrade from TD 2023 to TD 2025, but I noticed the Nvidia background removal node no longer works. The error message on the node states that it cannot find TensorRT. A similar post about Nvidia facetracking states that installing the 0.8.7 version of Nvidia’s AR sdk would solve it. Unfortunately it hasn’t. The background removal in the 2023 version still works, so I am a little confused as to what is actually going wrong.

I am using a RTX 2070 and installed the appropriate version of the SDK.

Thank you for reading,

Bas

Hey @Baas

We upgraded the version of NVIDIA Maxine SDK in 2025 builds which now requires the runtime dependencies to be manually installed. You can download it from here: NVIDIA Broadcast Software Integrations: Download Resources

The NVIDIA Background TOP specifically uses the Video Effects SDK, not the AR SDK. You’ll need to download the RTX 20 Series version of the Video Effects SDK to be compatible with your GPU.

Let me know if that works for you.

Thank you so much for the reply Daniel! This was exactly what was missing. Hopefully people having a similar problem can now find the solution here.
