我正在使用迁移学习方法训练 VGG 网络。（微调）但是在训练数据集时，我发现了以下错误，它停止了训练过程。

有人可以帮我在这里找出问题。

当它尝试下载 vgg16 的权重时，由于连接中断而显示错误。尝试手动下载权重。（链接：https ://github.com/fchollet/deep-learning-models/releases/download/v0.1/vgg16_weights_tf_dim_ordering_tf_kernels_notop.h5 ）

下载权重后，将其放入 keras 文件夹中名为“models”的文件夹中。keras 文件夹默认是隐藏的。

PathToFolder：C:\Users\UserName.keras\models。

完成此设置后，尝试运行代码。
