1）PaddlePaddle版本：请提供您的PaddlePaddle版本号：1.8.4 平台gpu 只对整个tensor赋值有效，单个元素无效 代码如下

with fluid.dygraph.guard():
    a = [[1,2,3,4,5],[6,7,8,9,0]]
    b = [[6,6,6,6,6],[6,7,8,9,0]]
    b = np.array(b)
    b = fluid.dygraph.to_variable(b)
    a = np.array(a)
    af = np.array([4])
    ae  = fluid.dygraph.to_variable(af).astype('int64')
    a  = fluid.dygraph.to_variable(a)
    a[0,1].set_value(ae)
    print(a[0,1])
    a.set_value(b)
    print(a)
