根据你提供的错误信息，错误出现在试图访问一个对象的lowvram属性时，但是这个对象是NoneType，也就是说这个对象实际上是None。在这种情况下，你无法访问其任何属性或方法。因此，你遇到了AttributeError: 'NoneType' object has no attribute 'lowvram'的错误。在代码中出现这个问题的部分应该是在调用 send_model_to_cpu 函数时尝试访问模型对象的 lowvram 属性。

为了解决这个问题，你需要确定为什么模型对象是 None。在大多数情况下，这是因为模型没有被正确地初始化或加载。检查模型初始化或加载的代码部分，确保模型已经被正确创建和赋值。这可能涉及到检查文件路径是否正确，模型是否已经成功加载等问题。另外，你需要确保调用 send_model_to_cpu 函数之前模型已经被正确地分配并初始化。如果你在使用深度学习框架（例如 PyTorch 或 TensorFlow），可能需要在加载预训练模型之后立即分配一个设备（CPU 或 GPU）。这通常在创建模型实例或加载模型权重时完成。如果设备分配有问题或者没有正确进行设备分配，可能会出现你遇到的这种错误。如果 sd_model 是从函数返回的，确保该函数在所有情况下都返回了一个有效的模型对象。如果 sd_model 是全局变量或者在其他地方被改变，确保它在被使用之前已经被正确初始化或赋值。如果问题仍然存在，你可能需要更深入地调试你的代码以确定为什么模型对象是 None。
