仍在下載甚至Keras在./keras/models

Question

中有VGG16預訓練模型我嘗試運行VGG16 keras腳本。 我得到這個錯誤：

Downloading data from https://github.com/fchollet/deep-learning-models/releases/download/v0.1/vgg16_weights_tf_dim_ordering_tf_kernels.h5 
Traceback (most recent call last):

Exception: URL fetch failure on https://github.com/fchollet/deep-learning-models/releases/download/v0.1/vgg16_weights_tf_dim_ordering_tf_kernels.h5: 

我試圖從here手動下載並粘貼到~/.keras/models。

但是，我仍然得到相同的錯誤。爲什麼？我不明白這個錯誤，因爲正確的模型已經在.keras/models。

默認值include_top參數VGG16功能是True。這意味着如果您想要使用全層預培訓的VGG網絡（具有完全連接的部件），則需要下載vgg16_weights_tf_dim_ordering_tf_kernels.h5文件，而不是vgg16_weights_tf_dim_ordering_tf_kernels_notop.h5。
