网络为分类模型，本地运行可以成功，提交到集群上面时，刚开始运行就出错

配置网络如下，集群版本内layers.py中没有seq_reshape_layer层，本地修改了这个文件后加了seq_reshape_layer层后提交到集群：

data_word = data_layer(name="word", size=num_word)
data_postag = data_layer(name="postag", size=num_postag)
data_arc = data_layer(name="arc", size=num_arc)
if not is_predict: 
    data_label = data_layer(name="label", size=num_classes)

word_attr = ParameterAttribute(initial_std=1/8.0, initial_mean=0.0)
tag_attr = ParameterAttribute(initial_std=1/4.0, initial_mean=0.0)
label_attr = ParameterAttribute(initial_std=1/4.0, initial_mean=0.0)

embedding_word = embedding_layer(input=data_word, size=word_dim, param_attr=word_attr)
srl_word = seq_reshape_layer(input=embedding_word, reshape_size=20*word_dim)
embedding_postag = embedding_layer(input=data_postag, size=postag_dim, param_attr=tag_attr)
srl_tag = seq_reshape_layer(input=embedding_postag, reshape_size=20*postag_dim)
embedding_arc = embedding_layer(input=data_arc, size=arc_dim, param_attr=label_attr)
srl_arc = seq_reshape_layer(input=embedding_arc, reshape_size=12*arc_dim)

concat = concat_layer(input=[srl_word, srl_tag, srl_arc], act=LinearActivation())
bias_attr = ParameterAttribute(initial_std=0., l2_rate=0.0001)
w_attr = ParameterAttribute(initial_std=1e-4, initial_mean=0.0)
hidden1 = fc_layer(input=concat, size=hidden_dim, act=ReluActivation(), param_attr=w_attr, bias_attr=bias_attr)
hidden2 = fc_layer(input=hidden1, size=hidden_dim, act=ReluActivation(), param_attr=w_attr, bias_attr=bias_attr)
output = fc_layer(input=hidden2, size=num_classes, act=SoftmaxActivation(), param_attr=w_attr, bias_attr=bias_attr)

if not is_predict: 
    cls_loss = classification_cost(input=output, label=data_label, evaluator=[precision_recall_evaluator, classification_error_evaluator])
    outputs(cls_loss)
else: 
    outputs(output)
