这个错误通常是由于安装的 protobuf 版本与使用的代码不兼容引起的。请检查您安装的 protobuf 版本是否与您的代码兼容。如果您使用的是旧版本的代码，请尝试安装旧版本的 protobuf。如果您使用的是新代码，请升级 protobuf 版本。您还可以尝试从源代码重新安装 protobuf，以确保它与您的代码兼容。

这个错误是由于 protobuf 库的版本不兼容导致的。建议你升级 protobuf 库的版本，或者降低 Keras 的版本。你可以尝试执行以下命令升级 protobuf 库：

pip install protobuf --upgrade

如果还是不能解决问题，你可以考虑降低 Keras 的版本。你可以执行以下命令来降低 Keras 的版本：

pip install keras==2.2.4

希望这些解决方案可以帮助到你。

根据错误信息，您的代码尝试在CUDA设备上反序列化对象，但是`torch.cuda.is_available()`返回False，这意味着您的系统上没有可用的CUDA设备。因此，您应该使用`torch.load`函数的`map_location`参数将模型加载到CPU上。

您可以尝试修改加载模型的代码，如下所示：

device = torch.device('cuda') if torch.cuda.is_available() else torch.device('cpu')
model = torch.load('demo/saveModel/handsModel.pth', map_location=device)

这样，在有可用的CUDA设备时，模型将被加载到CUDA设备上；如果没有可用的CUDA设备，则模型将被加载到CPU上。

尝试使用上述代码加载模型，看看是否可以解决问题。如果仍然遇到错误，请确保您已正确安装CUDA并配置了正确的环境。
