+* This `Dockerfile` installs `pre-cxx11-abi` versions of Pytorch and builds Torch-TRT using `pre-cxx11-abi` libtorch as well. Update on 1/17/2025: In torch 2.6, `PRE_CXX11_ABI` is required for CUDA 11.8 and 12.4, while `USE_CXX11_ABI` is required for CUDA 12.6. As of torch 2.7, torch requires `USE_CXX11_ABI` for all CUDA 11.8, 12.4, and 12.6.
 
 Note: By default the container uses the `pre-cxx11-abi` version of Torch + Torch-TRT. If you are using a workflow that requires a build of PyTorch on the CXX11 ABI (e.g. using the PyTorch NGC containers as a base image), add the Docker build argument: `--build-arg USE_CXX11_ABI=1`
