6 * Defines an IRPrinter that emits C++ code that:
7 * 1. wraps PyTorch's C++ tensor into Halide * buffers,
8 * 2. calls the corresponding Halide operator.
9 * 3. maps the output buffer back to a PyTorch tensor.
10 *
11 * The generated code checks for runtime errors and raises PyTorch exception
12 * accordingly. It also makes sure the GPU device and stream are consistent when
13 * the PyTorch input, when applicable.
