title: RuntimeError: _th_normal not supported on CPUType for Long
body: <p>I am trying to generate a number from the normal distribution using:</p>
  
  <pre><code>from torch.distributions import Normal
  noise = Normal(th.tensor([0]), th.tensor(3.20))
  noise = noise.sample()
  </code></pre>
  
  <p>But I am getting this error: <code>RuntimeError: _th_normal not supported on CPUType for Long</code></p>
