TimeoutError: [WinError 10060] 由于連接方在一段時間后沒有正確答復(fù)或連接的主機沒有反應(yīng)瘫俊，連接嘗試失敗鹊杖。
根據(jù)提示可以看到問題就是出在VGG的模型文件無法下載。鏈接是：https://storage.googleapis.com/tensorflow/keras-applications/vgg16/vgg16_weights_tf_dim_ordering_tf_kernels_notop.h5
解決方法
將這個鏈接使用瀏覽器下載下來扛芽，然后將文件復(fù)制到C:\Users\(用戶名)\.keras這個文件夾骂蓖，重現(xiàn)運行就可以了。
