'localization_net' is not defined

This error message indicates that there is no variable or function named 'localization_net' defined in the current scope of the code.

To resolve this error, you need to make sure that the 'localization_net' variable or function is properly defined and accessible in the current scope. This may involve checking the spelling and syntax of the variable or function name, ensuring that it has been imported or declared correctly, and verifying that it is not out of scope or out of scope.

If you are still having trouble resolving this error, please provide more context or code examples so that I can assist you further.

非常抱歉，之前的回答中遗漏了定义 `calculate_localization_error` 函数的部分。请将以下代码添加到你的实现中以定义该函数：

def calculate_localization_error(sensor_nodes):
    total_error = 0
    unknown_count = 0

    for node in sensor_nodes:
        if node.node_type == "unknown":
            total_error += math.sqrt((node.x - node.true_x)**2 + (node.y - node.true_y)**2)
            unknown_count += 1

    if unknown_count > 0:
        average_error = total_error / unknown_count
        return average_error
    else:
        return None

在上述代码中，我们定义了 `calculate_localization_error` 函数，用于计算节点的定位误差。我们遍历传感器节点列表 `sensor_nodes`，对于类型为 "unknown" 的节点，计算其实际位置 `(true_x, true_y)` 和估计位置 `(x, y)` 之间的欧几里得距离，并将所有节点的误差累加起来。最后，根据未知节点的数量计算平均误差，并返回该值。

请将上述代码添加到你的实现中，并再次运行。如果还有其他问题，请随时提问。非常抱歉给你带来的困扰！

非常抱歉，之前的回答中遗漏了定义 `calculate_localization_success_rate` 函数的部分。以下是一个示例实现该函数的代码：

def calculate_localization_success_rate(sensor_nodes):
    total_count = len(sensor_nodes)
    success_count = 0

    for node in sensor_nodes:
        if node.node_type == "unknown" and node.estimated_type == "unknown":
            success_count += 1

    if total_count > 0:
        success_rate = success_count / total_count * 100
        return success_rate
    else:
        return None

在上述代码中，我们定义了 `calculate_localization_success_rate` 函数，用于计算定位成功率。我们遍历传感器节点列表 `sensor_nodes`，对于类型为 "unknown" 的节点，并且其估计类型也为 "unknown"，我们将成功计数增加1。最后，根据节点总数计算成功率，并返回该值。

请将上述代码添加到你的实现中，并再次运行。如果还有其他问题，请随时提问。非常抱歉给你带来的困扰！
