wkcn edited a comment on issue #14361: [numpy] Add a global switch to turn 
on/off numpy compatibility

   when set_numpy_comp(True) is called, the output of some reduction operators 
Is always a scalar, which break the construct of computational graph, and not 
benefit for deployment.
   
   Example:
   ```python
   x = mx.nd.arange(6)
   x
   [0. 1. 2. 3. 4. 5.]
   <NDArray 6 @cpu(0)>
   x[1]
   [1.]
   <NDArray 1 @cpu(0)>
   
   float(x[1])
   1.0
   
   # 1-dim NDArray
   mx.nd.sum(x)
   [15.]
   <NDArray 1 @cpu(0)>
   
   # 0-dim NDArray
   mx.numpy.sum(x)
   15.0
   <NDArray 1 @cpu(0)>
   
   # built-in float
   float(mx.numpy.sum(x))
   15.0
   ```
