The reason may be in the method "gpytorch.random_variables.gaussian_random_variable.__add__", where in line 56, it tries to 

```Python
from ..variational import SumVariationalStrategy
```

However, in "gpytorch/gpytorch/variational/__init__.py", there's no SumVariationalStrategy being imported.

```Python
from .variational_strategy import VariationalStrategy
from .mvn_variational_strategy import MVNVariationalStrategy


__all__ = [
    VariationalStrategy,
    MVNVariationalStrategy,
]
```
ImportError: cannot import name 'SumVariationalStrategy'

I'm actually reopening this -- we don't even have `SumVariationalStrategy` any more, so it is the code in `gaussian_random_variable.py` that needs fixing. Sorry about that -- the import fix seemed to work because I had an old .pyc file lying around.
