title: removing redundant ipython kernels
body: <p>I have currently 3 environments: root(base), aind-dl, py2env</p>
  <p>So, for easy working, I've installed the conda extensions: nb_conda, nb_conda_kernels</p>
  <p>and when I run <code>$: jupyter notebook</code> the nb_conda_kernel detects 5 kernels which are redundant and in the listing. Some kernels gives an error of not existing.</p>
  <p>How do I remove the redundant kernels?</p>
