Brief According to the API doc of 'uniform_random' (see http://paddlepaddle.org/documentation/docs/zh/1.2/api/layers.html#uniform-random), the default 'dtype' is:

dtype (INT) – Output tensor data type. [default 5(FP32)].

But in fact, the dtype of returned tensor is not set to 5. System information -PaddlePaddle version: 1.2.1 -OS Platform and Distribution: Ubuntu 18.04 -Python version: Python 2.7.15rc1 To Reproduce Just use the code provided in API doc:

import paddle.fluid as fluid
result = fluid.layers.uniform_random(shape=[32, 784])
print result

Describe your current behavior

Traceback (most recent call last):
