reminisce commented on issue #14105: nd.slice errors out when end=-1 and step=-1
URL: https://github.com/apache/incubator-mxnet/issues/14105#issuecomment-466737500
 
 
   According to numpy, this should return an empty array. Since MXNet does not support emtpy array in computation, it simply throws exception. So there is nothing wrong for now until we support empty arrays which has been planned.
   ```python
   >>> import numpy as np
   >>> data = np.random.uniform(size=(4,))
   >>> data
   array([0.19584417, 0.05437645, 0.73802081, 0.20259332])
   >>> data[2:-1:-1]
   array([], dtype=float64)
   ```
