For improved conciseness and consistency with other examples in this file (like the map function's docstring), consider using a list comprehension. This is generally the preferred Pythonic way to build a list.

This would simplify the body of the example function to a single line.

Suggested change
outputs = []
for e in elements:
outputs.append(function(e))
return stack(outputs)
return np.stack(outputs)
return np.stack([function(e) for e in elements])

```

In the case of an iterable of tensors `elements`,
it implements the following:

```python
def vectorized_map(function, elements)
def vectorized_map(function, elements):
batch_size = elements[0].shape[0]
outputs = []
for index in range(batch_size):
