can't assign a Ch objects as a subset of another #11
Comments

As the error says, you cannot assign Ch objects to others. You can either assign a numpy array to k or stack 9 Ch objects. |

These namespace relative imports work in chumpy tests, but were causing import errors like this one:
```
File "/home/circleci/repo/blmath/geometry/transform/test_composite.py", line 172, in test_forward_reverse_equivalence

I am trying to assign a 3x3 array as a subset of a 3x3x9 array, but it gives me
Exception: Can't assign a Ch objects as a subset of another.
The following code is troublesome:
k = ch.arange(81).reshape(3, 3, 9)tmp = ch.eye(3)k[:, :, 1] = tmpThe complete error message is the following:
Traceback (most recent call last):
File "", line 1, in

raise Exception("Can't assign a Ch objects as a subset of another."
