title: What does "pypi" in the "Channel" column of `conda list` output imply?
body: <pre><code>$ conda list -v torch-glow
  # packages in environment at /anaconda3/envs/pytorch:
  #
  # Name                    Version                   Build  Channel
  torch-glow                0.0.0                    pypi_0    pypi
  </code></pre>
  
  <p>Does it mean that I <code>pip install</code>'d the <code>torch-glow</code> package?</p>
