  I already have tried the suggestion from <a href="https://stackoverflow.com/questions/45904828/io-h-no-such-file-or-directory">&#39;io.h&#39;: No such file or directory</a></p>
  
  <p>but didn't work, I have visual studio 2017 and anaconda. I went to my directory and there is no io.h file there, so did I miss something when I installed visual studio? How do I fix  that?
