@judy commented on GitHub (Mar 15, 2023):

I got this too and was able to fix it by reading this comment on the rembg repo. In short:

  1. You'll want to make sure you have the right versions of CUDA, cuDNN, and Nvidia TensorRT. I ended up installing all three of those. (The link says to use CUDA 11, but I needed CUDA 12.)
  2. Once installed, make sure the paths to the folders containing those DLLs are on your PATH when running the interface. Instead of modifying my system environment variables, I changed my webui-user.bat file to change the PATH like this:
set PATH=C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v12.1\bin;C:\Program Files\Common Files\TensorRT-8.6.0.12\lib;%PATH%

Adjust that yourself based on what the folders are on your own system. TensorRT in particular came as a zip file and no installer, so I stuck it in C:\Program Files\Common Files. No idea if that's the ideal location for that sort of thing, so your mileage will vary!

Awesome it's working now, on my setup I went for:

  • cuda 11.8
  • cudnn 8.8.1.3 (for cuda 11)
  • tensorrt 8.6.0.12 (for cuda11)
