AttributeError: module 'theano.tensor' has no attribute 'slinalg'

I was using the following code previously without any error but now I have problems

import theano.tensor as tt
tt.slinalg
 > AttributeError: module 'theano.tensor' has no attribute 'slinalg'

Or maybe you need to import theano.tensor.slinalg explicitly?

pip install -U git+https://github.com/Theano/Theano does not help I get another error instead:

FileNotFoundError: [Errno 2] No such file or directory: '/Users/ferres/.pyenv/versions/3.6.0/envs/pymc3-py3/lib/python3.6/site-packages/theano/tensor/c_code/dimshuffle.c'

cloning the whole project and pip install -e .seems to resolve FileNotFoundError problem (direct install still does not work). The main problem with slinalg still occurs

Try @lamblin suggestion. I think he have the right fix. The file isn't imported automatically as it depend on scipy and scipy is an optional dependency.
