title: How to switch environment on Jupyter notebook for new notebook?
body: <p>I have an instance with various environment and some notebooks are compatible with different environment for e.g. notebook1 is for MXNet and notebook2 is for Tensorflow.  </p>
  
  <p>How do I jump to new environment when I move from notebook1 to notebook2? 
  I tried doing that but this doesn't quite work with Jupyter notebook? Any suggestion?</p>
  
  <p>So I need to do it from conda environment but looks like jupyter notebook  UI doesn't respect (calls right activation function) to set the path. </p>
