title: Convert Torch Lua into Numpy Python
body: <p>Am looking to convert some Lua Torch code into numpy Python.
  I google for find some documentations, but it still unclear.</p>
  
  <p>I found this.
  <a href="https://nn.readthedocs.io/en/rtd/index.html" rel="nofollow">https://nn.readthedocs.io/en/rtd/index.html</a></p>
  
  <p>Wondering if there is any mapping between Lua Torch functions and numpy functions ?</p>
  
  <p>Thanks</p>
