When verifying my tensorflow installation as per the instructions here: https://www.tensorflow.org/install/install_mac#ValidateYourInstallation
I get the following error message immediately after importing tf:
(tensorflow) Davids-iMac:~ david$ python

I have had this problem on two different Macs; this installation was in a virtualenv, the other installation python directly. I installed python 3, readline and pip from scratch with Macports using sudo -H.
I also used sudo port select --set python python36 to set python3 to be the default (same for pip3).
Any hints where I went wrong greatly appreciated.
Here the virtualenv installation of tf: cd /opt/local/bin sudo ln -s /opt/local/Library/Frameworks/Python.framework/Versions/3.6/bin/virtualenv cd
virtualenv --system-site-packages -p python3 tensorflow/
The path python3 (from --python=python3) does not exist
Davids-iMac:~ david$ virtualenv --system-site-packages -p python tensorflow/
