【 百度 paddlepaddle 使用dropout 时】出现 ：TypeError: ‘Tensor‘ object is not callable

import paddle
import numpy as np

x = np.array([[1,2,3], [4,5,6]]).astype('float32')
x = paddle.to_tensor(x)

#######################
p =paddle.nn.functional.dropout(x) 
y_train=p(x)# 这种方式报错！
###############################

y_train = paddle.nn.functional.dropout(x, 0.5) ###这是正确的使用方式

print(x)
print(y_train)

print(x)
print("经过drop_out 的数据",y_train)

由于才学习python 和百度paddlepaddle框架，我觉得这个错误的原因是，平时定义卷积神经网络的方式是引用Conv2D等类，然后实例化。这个paddle.nn.functional.dropout（）是不是只是个函数？
乱猜的，反正要添加Drop_out层，直接调用这个函数就完了。别再像下面的代码那样错误操作了。
