   can we just use ndarray to compute instead of converting to numpy? if there is a number of classes, say 10K, then it could be problematic
   
   a sample code:
   
   ```
   def accuracy(output, label):
       # both output and label are ndarray
       return (output.argmax(axis=1)==label).sum().asscalar()
   ```
