Errors when running xgboost and dense neural net tutorial decoders

[srcole]

I'm trying to get the tutorials to run, but I am having issues with 2 of the decoders.

When running cell 4C (xgboost), I get this error on line 686 of decoders.py
AttributeError: 'module' object has no attribute 'DMatrix'

When running cell 4E (dense neural net), I get an error in keras/backend/tensorflow_backend.py on line 1107 (when calling tf.python.control_flow_ops.cond):
AttributeError: 'module' object has no attribute 'control_flow_ops'

I'm using a python 3.4 conda virtual environment and installed keras by conda install -c conda-forge keras. and cloned the current version of xgboost.

Would appreciate any advice on how to get these working with my environment. Thanks!

I'm really sorry for the delay in getting back to you! Did you end up getting either to work, or are you still stuck?

no worries! It's not critical for my project, so I honestly haven't looked at it since opening this issue.
