x = paddle.layer.data(name='x',type=paddle.data_type.dense_vector(3))
predict = paddle.layer.fc(input = x,size=1,act=paddle.activation.Linear())
y = paddle.layer.data(name='y',type=paddle.data_type.dense_vector(1))
cost = paddle.layer.square_error_cost(input=predict, label=y)
param = paddle.parameters.create(cost)
optimizer = paddle.optimizer.Momentum(momentum=0)
**trainer = paddle.trainer.SGD(cost = cost,parameters = param,update_equation = optimizer)**

在自己开发机上执行类似线性回归代码，执行到trainer = paddle.trainer.SGD(cost = cost,parameters = param,update_equation = optimizer)这一句时候报错，报错信息如下： WARNING: Logging before InitGoogleLogging() is written to STDERR F0110 17:47:11.161947 31590 ClassRegistrar.h:65] Check failed: mapGet(type, creatorMap_, &creator) Unknown class type: poly
