paddle训练出现这样的错误，怎么解决？

Question

PaddlePaddle 1.1.0, compiled with

代码：

import paddle.v2 as paddle 

paddle.init(use_gpu=False, trainer_count=1)

x = paddle.layer.data(name='x', type=paddle.data_type.dense_vector(13)) 
y_predict = paddle.layer.fc(input=x, size=1, act=paddle.activation.Linear()) 

probs = paddle.infer( 
    output_layer=y_predict,
    parameters=paddle.dataset.uci_housing.model(), 
    input=[item for item in paddle.dataset.uci_housing.test()()]) 
for i in xrange(len(probs)): 
    print 'Predicted price: ${:,.2f}'.format(probs[i][0] * 1000)

结果：

 I1122 20:00:13.175132  6741 Util.cpp:166] commandline:  --use_gpu=False --trainer_count=1

看你的堆栈，似乎是很底层的错误，你是不是gpu没有配置对。
