从 Anaconda Python 3.6 降级到 Python 3.5.2 不起作用

Question

I am trying to downgrade python to 3.5.2 so I can run TensorFlow. Running into a bit of an issue here, not sure why. I open my cmd and run python - shows me Python 3.6.1 is running. Exit() out of cmd, then type conda install python=3.5.2 . It shows that 3.5.2 is currently installed, but for whatever reason when I'm in cmd and python it keeps showing my that python is in verison 3.6. Any idea how to fix this?

If you're using anaconda, a better idea would be to start a new environment rather than trying to install a new python in an old environment. That's basically asking for the same set of problems that virtual environments are made to circumvent ;-)

conda create -n py35 python=3.5.2
source activate py35
