class InvalidTorchDType(
*args,
**kwargs,
)[source]

Bases: object

Default return type for torch_dtype when an invalid data is passed as argument of scan_torch_dtype function. (like str for example)

Returns the shape and the hdf_dtype for an input.

scan_torch_dtype(
x: Any,
*,
invalid: T_Invalid = InvalidTorchDType(),
empty: T_EmptyTorch | None = None,
) → dtype | T_Invalid | T_EmptyTorch[source]

Returns torch dtype of an arbitrary object. Works recursively on tuples and lists. An instance of InvalidTorchDType can be returned if a str is passed.
