Maybe worth noting, at the moment if you try to call argmin(dim=("x", "y")) with multiple dimensions, there's a not-very-helpful exception ```

array.argmin(dim=("x", "y")) Traceback (most recent call last): File "/home/john/anaconda3/lib/python3.7/site-packages/numpy/core/fromnumeric.py", line 61, in _wrapfunc return bound(args, *kwds) TypeError: 'tuple' object cannot be interpreted as an integer

During handling of the above exception, another exception occurred:
