Arguments | |
---|---|
x
|
A tensor or variable. |
axis
|
An integer, the axis to compute the variance. |
keepdims
|
A boolean, whether to keep the dimensions or not.
If keepdims is False , the rank of the tensor is reduced
by 1. If keepdims is True ,
the reduced dimension is retained with length 1.
