I had the same issue, and the command below (as indicated in https://github.com/tensorflow/tensorflow/issues/10779) helped:
/Applications/Python\ 3.6/Install\ Certificates.command
I suggest you install TensorFlow in a separate virtualenv.
Follow the following steps here: Installing TensorFlow with virtualenv
And always remember to activate the virtualenv environment each time you use TensorFlow in a new shell by running:
$ source ~/<target_directory>/bin/activate
I installed the latest version of Pip and the issue was fixed
Update using the following command:
"pip install --upgrade pip"
TensorFlow 2 packages require a pip version >19.0.
I am trying to configure sublime text 3 with AngularJS. I copied the message i found on the internet for sublime text 3 to the console to install the package controller:
