title: Google colab: printing in child processes
body: <p>I can't see any output in a google colab when I use python <code>Process</code>. I tried <code>print</code> function and <code>logging</code> module but it doesn't work.
  This simple example produces output on my machine (jupyter notebook, python 3.6.9) but doesn't work in colab:</p>
  <pre><code>from multiprocessing import Process
  import time
  
  def simple_fun(proc_id):
      while True:
          time.sleep(1)
          print(proc_id)
      
  N_PROCESS = 2
  processes = []
  for i in range(N_PROCESS):
      p = Process(target=simple_fun, args=(i,))
      p.start()
      processes.append(p)
  </code></pre>
  <p>Is there anything I can do?</p>
  <p>Am I missing something? May be the code above is platform-depended?</p>
