replace `from .nnet import *`

```from .nnet import *``` in ```theano/tensor/nnet/__init__.py``` is causing problems because ```nnet``` imports ```theano.tensor.opt``` as ```opt``` which takes namespace place of ```theano.tensor.nnet.opt```. To fix this problem, I replace ```from .nnet import *``` by ```from .nnet import (every class/functions/attributes)``` Added the following code at the end of the file ```theano/tensor/nnet/nnet.py``` ```python print locals().keys() ``` And then copied the output ```bash $ python theano/tensor/nnet/nnet.py ['keys', 'of', 'locals', ...] ``` Removed last line of code in ```theano/tensor/nnet/nnet.py``` and added following code under the imports ```python keys = ['keys', 'of', 'locals', ...] # pasted the copied output from previous step local_keys = locals().keys() keep = filter(lambda a: a not in local_keys and a[0] != '_', keys) print sorted(keep) ``` And again ```bash $ python theano/tensor/nnet/nnet.py ['keys', 'of', 'locals', 'minus', 'imports', 'and', 'private'...] ``` Those are the class/function names to be added to ```theano/tensor/nnet/__init__.py```. ```python from .nnet import ( keys, of, locals, minus, imports, and, private, ...) ```
