tensordot(a: array, b: array, /, axes: Union[int, List[List[int]]] = 2, *, stream: Union[None, Stream, Device] = None) -> array
Compute the tensor dot product along the specified axes.
Args:
a (array): Input array
b (array): Input array
dims (int or list(list(int)), optional): The number of dimensions to
axes (int or list(list(int)), optional): The number of dimensions to
sum over. If an integer is provided, then sum over the last
``dims`` dimensions of ``a`` and the first ``dims`` dimensions of
``axes`` dimensions of ``a`` and the first ``axes`` dimensions of
``b``. If a list of lists is provided, then sum over the
corresponding dimensions of ``a`` and ``b``. (default: 2)
