shitou112 opened a new issue #9455: An error occurred while calculating the 
square of ndarray by using gpu context
URL: https://github.com/apache/incubator-mxnet/issues/9455
 
 
   #### 1. When I use a**2 to compute square, I encounter an error. 
   ```
   Input: a = nd.array([-1], mx.gpu())
          a ** 2
   
   Output: [ nan]
           <NDArray 1 @gpu(0)>
   ```
   #### 2. However, when using ctx=mx.cpu(), the result is right.
   ```
   Input: a = nd.array([-1], mx.cpu())
          a ** 2
   
   Output: [ 1.]
           <NDArray 1 @cpu(0)>
   ```
   
   #### 3. when I use a*a to compute square, the result is also right.
   ```
   Input: a = nd.array([-1], mx.gpu())
          a * a
   
   Output: [ 1.]
           <NDArray 1 @gpu(0)>
   ```
