If one attempts to import `torch.utils.flop_count` on MacOS (or any other CPU system), they'll be greated with the following repeated warning ``` % python -c "import torch.utils.flop_counter" W0115 18:52:55.246000 34027 torch/utils/flop_counter.py:45] triton not found; flop counting will not work for triton kernels W0115 18:52:55.246000 34027 torch/utils/flop_counter.py:45] triton not found; flop counting will not work for triton kernels W0115 18:52:55.246000 34027 torch/utils/flop_counter.py:45] triton not found; flop counting will not work for triton kernels W0115 18:52:55.247000 34027 torch/utils/flop_counter.py:45] triton not found; flop counting will not work for triton kernels W0115 18:52:55.247000 34027 torch/utils/flop_counter.py:45] triton not found; flop counting will not work for triton kernels W0115 18:52:55.247000 34027 torch/utils/flop_counter.py:45] triton not found; flop counting will not work for triton kernels W0115 18:52:55.247000 34027 torch/utils/flop_counter.py:45] triton not found; flop counting will not work for triton kernels W0115 18:52:55.247000 34027 torch/utils/flop_counter.py:45] triton not found; flop counting will not work for triton kernels W0115 18:52:55.247000 34027 torch/utils/flop_counter.py:45] triton not found; flop counting will not work for triton kernels W0115 18:52:55.247000 34027 torch/utils/flop_counter.py:45] triton not found; flop counting will not work for triton kernels W0115 18:52:55.247000 34027 torch/utils/flop_counter.py:45] triton not found; flop counting will not work for triton kernels W0115 18:52:55.247000 34027 torch/utils/flop_counter.py:45] triton not found; flop counting will not work for triton kernels W0115 18:52:55.247000 34027 torch/utils/flop_counter.py:45] triton not found; flop counting will not work for triton kernels ``` which was introduced by #169876 Move import to top of flop_counter utils and only warn if system is compiled with GPU support that requires triton (i.e. CUDA/ROCM or XPU) ghstack-source-id: d2f3c83 Pull-Request: #172614
