easygraph.datapipe.common module

easygraph.datapipe.common.compose_pipes(*pipes: Callable) → Callable

Compose datapipe functions.

Parameters:

pipes (Callable) – Datapipe functions to compose.

easygraph.datapipe.common.to_bool_tensor(X: List | numpy.ndarray | torch.Tensor) → torch.BoolTensor

Convert List, numpy.ndarray, torch.Tensor to torch.BoolTensor.

Parameters:

X (Union[List, np.ndarray, torch.Tensor]) – Input.

Examples

>>> import easygraph.datapipe as dd
>>> X = [[0.1, 0.2, 0.5],
         [0.5, 0.2, 0.3],
         [0.3, 0.2, 0]]
>>> dd.to_bool_tensor(X)
tensor([[ True,  True,  True],
        [ True,  True,  True],
        [ True,  True, False]])

easygraph.datapipe.common.to_long_tensor(X: List | numpy.ndarray | torch.Tensor) → torch.LongTensor

Parameters:

X (Union[List, np.ndarray, torch.Tensor]) – Input.

Examples

>>> import easygraph.datapipe as dd
>>> X = [[1, 2, 5],
         [5, 2, 3],
         [3, 2, 0]]
>>> dd.to_long_tensor(X)
tensor([[1, 2, 5],
        [5, 2, 3],
