V2 test are broken

[NicolasHug]

Because we error on warnings and we get the following:

2023-10-09T08:08:44.6345575Z FAILED test/test_transforms_v2.py::TestRgbToGrayscale::test_transform[make_image_tensor-transform1] - UserWarning: torch::jit::fuser::cuda::isEnabled() is deprecated (Triggered internally at ../torch/csrc/jit/codegen/cuda/interface.cpp:54.)

This happens on pure CPU job where clearly there's nothing related to nvfused or even CUDA. The warning was emmitted in this PR: pytorch/pytorch#110318

Actually this is unrelated to the transforms, even pure torch API will throw the warning. I opened pytorch/pytorch#110857
