broadcast_all function

Given a list of values (possibly containing numbers), returns a list where each value is broadcasted based on the following rules:

Raises value_error: if any of the values is not a numeric instance, a torch.*Tensor instance, or an instance implementing torch_function

broadcast_all(values)

Arguments

• values: List of:

  • torch.*Tensor instances are broadcasted as per _broadcasting-semantics.
  • numeric instances (scalars) are upcast to tensors having the same size and type as the first tensor passed to values. If all the values are scalars, then they are upcasted to scalar Tensors. values (list of numeric, torch.*Tensor or objects implementing torch_function )
