执行python train.py 后报错：

[CRITICAL 2017-12-01 16:59:20,940 layers.py:1058] When the name field of param_attr is manually specified and the input is a list, the param_attr should also be a list with each item being the param_attr for each input item. If only one named param_attr is provided, all the input items would share this parameter.

主要是由于fc_layer的更新，使得不能默认的共享参数，导致报错。
