如题，使用示例Paddle/python/paddle/fluid/tests/book/test_label_semantic_roles.py，我发现在给crf层添加正则项后，会出现下面这个报错。 修改是在第167行，修改后的crf层也就是如下 crf_cost = fluid.layers.linear_chain_crf( input=feature_out, label=target, param_attr=fluid.ParamAttr( name='crfw', learning_rate=mix_hidden_lr, regularizer=fluid.regularizer.L2DecayRegularizer(regularization_coeff=0.1))) 辛苦追查一下原因。
