title: How to set the environment default python in anaconda?
body: <p>It makes me crazy, In anaconda I create the environment with the defualt iterpreter python3.4   Next I install pytorch 0.4.1</p>
  
  <pre><code>conda install pytorch=0.4.1 cuda80 -c pytorch
  </code></pre>
  
  <p>After this I found that the pytorch was installed in python3.6!</p>
  
  <p>And the environment defualt interpreter is chaged from python3.4 to python3.6.</p>
  
  <p>I am very confused what happend ? How shoud I fix it back? change defualt python back to python3.4? Hope some one could help me.</p>
  
  <p>The commands I typed in are as follows:</p>
  
  <pre><code>conda create -n pointgen python=3.4 ipykernel
  source activate pointgen
  conda install pytorch=0.4.1 cuda80 -c pytorch
  </code></pre>
  
  <p>Thats all. What Novak said is right, there is remaining question is how could I manually change the python version from 3.6 back to 3.4, is there any config file I can deal with?</p>
