Thank you, it was crystal clear ...
Can we use the same propt to install theano and tensorflow

like:

conda install -c conda-forge theano
conda install -c conda-forge tensorflow

this was the first thing that showed up
WARNING: The conda.compat module is deprecated and will be removed in a future release.
what does this mean?

thanks

I followed your instruction but got the following error, could you help,
Anaconda version: Anaconda3-5.3.1-Windows-x86_64

Got error:
CondaError: Cannot link a source that does not exist. C:\ProgramData\Anaconda3\Scripts\conda.exe

Running `conda clean --packages` may resolve your problem.

Conda install c conda forge keras
