Cannot import Kuu name

[Mirgahney]

Hi Hugh,

We I was trying to import deep GP from doubly_stochastic_dgp.dgp import DG I get the following error:

---------------------------------------------------------------------------

ImportError: cannot import name 'Kuu'

and I'm using GPflow 1.1.1

Hi thanks for pointing this out. The code is not compatible with gpflow1.1. It should work with gpflow1.0, however.

I will try to refactor the code for compatibility with gpflow1.1 later today.

[hughsalimbeni]

I've thought a bit more about this and think it's not worth refactoring right now as tensorflow2 and gpflow2 are very soon to be released. These new version will incur major refactoring, including much simplification (e.g. no autoflow), so I don't think it's worth changing things at this stage. To get the above code to work the Kuu import can be dropped and then the matrix can be created using something likekern.K(Z) + tf.eye(M) * jitter

Hi, I am facing the same problem with gpflow 1.5.0 , tensorflow 1.14.0 and python 3.7
AttributeError: 'InducingPoints' object has no attribute 'Kuu'
Tensorflow 1.8 is incompatible for python 3.7.
After installing gpflow 1.0 here's another problem
from gpflow.training import AdamOptimizer ImportError: cannot import name 'AdamOptimizer' from 'gpflow.training' (/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/gpflow/training/__init__.py)

[hughsalimbeni]

Perhaps try gpflow1.4?

[hughsalimbeni]

Or 1.1

[LanyeHu]

Thanks. I changed the version of gpflow to 1.3.0, tensorflow to 1.13.1 and it works.
