+ Parameters
+ ----------
+ low : int, optional
+ Lower boundary of the output interval. All values generated will be
+ greater than or equal to low. The default value is 0.
+ high : int, optional
+ Upper boundary of the output interval. All values generated will be
+ less than high. The default value is 1.
+ shape : int or tuple of ints, optional
+ The number of samples to draw. If shape is, e.g., `(m, n)` and `low`
and
+ `high` are scalars, output shape will be `(m, n)`.
+ dtype : {'int32', 'int64'}, optional
+ Data type of output samples. Default is 'int32'

Review comment:
Please test it on GPU. Also you might want to check if curand support int64.
