Hi, if I used python2.7 I got the same syntax error with #19.
And then I transform to python 3.7 I got another new error:
def _required(bbox: Optional[BoundingBox]) -> BoundingBox:
NameError: name 'Optional' is not defined

Is any help for this issue?

* Fix for AxisError with numpy 1.18

FFN fails with
`numpy.AxisError: axis 4 is out of bounds for array of dimension 4`

when numpy 1.18 is used.

See the 1.18 note for numpy.expand_dims at
https://numpy.org/doc/stable/reference/generated/numpy.expand_dims.html
```
axis int or tuple of ints
Position in the expanded axes where the new axis (or axes) is placed.

Deprecated since version 1.13.0: Passing an axis where axis > a.ndim will be treated as axis == a.ndim, and passing axis < -a.ndim - 1 will be treated as axis == 0. This behavior is deprecated.

Changed in version 1.18.0: A tuple of axes is now supported. Out of range axes as described above are now forbidden and raise an AxisError.
```

* Fix import error

Training fails since Optional was not imported
