max_pool

def max_pool[dtype: DType, int_type: DType, target: StringSlice[ImmStaticOrigin] = StringSlice("cpu")](input: TileTensor[dtype, Storage=input.Storage, address_space=input.address_space, linear_idx_type=input.linear_idx_type], filter: TileTensor[int_type, Storage=filter.Storage, address_space=filter.address_space, linear_idx_type=filter.linear_idx_type], strides: TileTensor[int_type, Storage=strides.Storage, address_space=strides.address_space, linear_idx_type=strides.linear_idx_type], dilations: TileTensor[int_type, Storage=dilations.Storage, address_space=dilations.address_space, linear_idx_type=dilations.linear_idx_type], paddings: TileTensor[int_type, Storage=paddings.Storage, address_space=paddings.address_space, linear_idx_type=paddings.linear_idx_type], output: TileTensor[dtype, Storage=output.Storage, address_space=output.address_space, linear_idx_type=output.linear_idx_type], ceil_mode: Bool = False, ctx: Optional[DeviceContext] = None)

Dispatches the max pooling operation to the CPU or GPU backend based on the target.

Parameters:

dtype (DType): Data type of the input and output tensors.
int_type (DType): Data type of the filter, strides, dilations, and paddings tensors.
target (StringSlice[ImmStaticOrigin]): Execution target, either "cpu" or "gpu".

Args:

input (TileTensor[dtype, Storage=input.Storage, address_space=input.address_space, linear_idx_type=input.linear_idx_type]): Batched image input to the pool2d operator.
filter (TileTensor[int_type, Storage=filter.Storage, address_space=filter.address_space, linear_idx_type=filter.linear_idx_type]): Filter size on height and width dimensions with assumed tuple (filter_h, filter_w).
strides (TileTensor[int_type, Storage=strides.Storage, address_space=strides.address_space, linear_idx_type=strides.linear_idx_type]): Strides on height and width dimensions with assumed tuple (stride_h, stride_w).
dilations (TileTensor[int_type, Storage=dilations.Storage, address_space=dilations.address_space, linear_idx_type=dilations.linear_idx_type]): Dilations on height and width dimensions with assumed tuple (dilation_h, dilation_w).
paddings (TileTensor[int_type, Storage=paddings.Storage, address_space=paddings.address_space, linear_idx_type=paddings.linear_idx_type]): Paddings on height and width dimensions with assumed tuple (pad_h_before, pad_h_after, pad_w_before, pad_w_after)).
output (TileTensor[dtype, Storage=output.Storage, address_space=output.address_space, linear_idx_type=output.linear_idx_type]): Pre-allocated output tensor space.
ceil_mode (Bool): Ceiling mode defines the output shape and implicit padding.
ctx (Optional[DeviceContext]): The DeviceContext to use for GPU execution.
