title: Source Activate Conda
body: <p>I am a new user to conda environment and was setting up to use TensorFlow , on Windows.
  I came across a command -
  source activate IntroToTensorFlow.</p>
  
  <p>I understood IntroToTensorFlow is an environment we are creating, but does it mean we need to create this environment every time?. I am using jupyter notebook, so if I shutdown the kernel will the environment get deactivated?
  And if I restart my PC, should I activate the environment everytime ?</p>
