Python NotFoundError:使用TensorFlow时，在检查点中找不到键变量

我阅读了TensorFlow使用Seq2SeqModel的translate.py，并对其感兴趣，我想使用两个seq2seq模型（BotEngine，GrammarGenerator），使用TF教程代码中使用的translate.py，如下所示

    with tf.Session() as sess:
    with tf.variable_scope("be_model"):
        model_be = BotEngine.create_model(sess, True)
        print("be model created")
    with tf.variable_scope("gg_model"):
        model_gg = GrammarGenerator.create_model(sess, True)
        print("gg model created")

当我分别训练和测试这两个模型时（在读取检查点文件之后），没有发生错误。但是，当我连续读取两个检查点文件时，会出现以下错误：
