   What version of MXNet are you using? Works fine for me in version 1.0.0.
   
   ```python
   $ pip list | grep mxnet
   DEPRECATION: The default format will switch to columns in the future. You can use --format=(legacy|columns) (or define a format=(legacy|columns) in your pip.conf under the [list] section) to disable this warning.
