- class ray.data.extensions.tensor_extension.ArrowVariableShapedTensorType(dtype: pyarrow.lib.DataType, ndim: int)[source]#
Arrow ExtensionType for an array of heterogeneous-shaped, homogeneous-typed tensors.
This is the Arrow side of TensorDtype for tensor elements with different shapes. Note that this extension only supports non-ragged tensor elements; i.e., when considering each tensor element in isolation, they must have a well-defined, non-ragged shape.
See Arrow extension type docs: https://arrow.apache.org/docs/python/extending_types.html#defining-extension-types-user-defined-types

Convert Arrow extension type to corresponding Pandas dtype.
An instance of pd.api.extensions.ExtensionDtype.
- property ndim: int#
Return the number of dimensions in the tensor elements.
- property scalar_type#
Returns the type of the underlying tensor elements.
