astensors

astensors(*values: Any, conversion: Callable[[Any], Tensor] | None = None) → tuple[Tensor, ...] | Tensor

Converts inputs into tensors.

If any value is a tensor, it will be used as a reference and non-tensor inputs will be converted using scalar(). If there are no tensors, then all elements will be converted into tensors using conversion. When determining a reference, the leftmost tensor will be used.

Parameters:

• *values (Any) – values to convert into tensors

• conversion (Callable[[Any], torch.Tensor] | None) – method to convert values if none are tensors, the default if unspecified. Defaults to None.

Returns:

converted values.

Return type:

tuple[torch.Tensor, …] | torch.Tensor
