Call the Model first, then load the weights.怎么改

在 `run` 函数中，我们应该先创建模型，再加载权重。所以我们需要将创建模型和加载权重的顺序调换一下，同时将模型命名为 `modelaaa`，但在 `predict` 中使用的却是 `model`，需要将其改为 `modelaaa`。修改后的代码如下：

def run(Domain):
    Domains = data(Domain)
    modelaaa = build_model(max_features=1, maxlen=65)
    modelaaa.load_weights('Mymodel.h5')
    predictions = modelaaa.predict(Domains)
    return predictions

这样就可以避免 `Unable to load weights saved in HDF5 format into a subclassed Model which has not created its variables yet. Call the Model first, then load the weights.` 的错误了。

要初始化这个函数中的模型，我们只需要调用这个函数即可，这将返回一个已编译好的Keras模型对象。以下是一个示例：

max_features = 10000
maxlen = 100

model = build_model(max_features, maxlen)

在这个示例中，我们将“max_features”设置为10000，“maxlen”设置为100，并调用“build_model”函数来构建模型。这将返回一个已编译好的Keras模型对象“model”，我们可以使用它来进行训练和预测。例如，我们可以使用以下代码来编译模型并训练它：

model.compile(optimizer='adam', loss='binary_crossentropy', metrics=['accuracy'])
model.fit(x_train, y_train, batch_size=32, epochs=10, validation_data=(x_test, y_test))

在这个示例中，我们使用“model.compile”方法来编译模型，指定优化器、损失函数和评估指标。然后，我们使用“model.fit”方法来训练模型，指定训练数据、批大小、训练轮数和验证数据。这将训练模型并返回训练结果。

这段代码是一个使用 LSTM 模型对域名进行分类的程序，其中包括了模型的构建和加载，以及对数据进行预处理和预测。具体来说，该程序使用了 Keras 和 TensorFlow 库进行模型的建立和训练，同时使用了 pickle 库进行数据的读取和存储。在运行该程序时，输入一个域名进行分类，输出该域名属于恶意或者良性的概率。
