I ran the s&p-500-regression example without modification and I got

Make sure both your Python and Keras perferences point to the new Python35 environment.
How?
hello @werbungsbunker - welcome to the community. You will find that in Preferences.
Scott
It points to "E:\Anaconda\python.exe" now, but I still get the error message. I installed keras and tensorflow-gpu using conda and running a python shell and importing keras works. So what else causes this error?
hmm - I will kindly ask my Windows experts to chime in
@Thomas_Ott ?
Did you create a specific Tensorflow environment like what the KB said to do? If yes, and both the Python perference and Keras perference point to E:\Anaconda\<environment name>\python.exe and you get the same error then it's something else.
