# specifically for the 'triton' module. This means `import torch` inside 'triton'
# will actually import paddle's compatibility layer (acting as torch).
#
# 'scope' acts as an allowlist. To add other modules, you can do:
# paddle.compat.enable_torch_proxy(scope={"triton", "new_module"})
#
# Note: Ensure that any torch APIs used in 'new_module' are already implemented in Paddle.
