下載下傳了 cudnn-6.5-linux-x64-v2.tgz 并且按照上面說的安裝完畢後,發現,原本的錯誤是沒了,但是有了新的錯誤提示:
E tensorflow/stream_executor/cuda/cuda_dnn.cc:378] Loaded runtime CuDNN library: 2000 (compatibility version 2000) but source was compiled with 5105 (compatibility version 5100). If using a binary install, upgrade your CuDNN library to match. If building from sources, make sure the library loaded at runtime matches a compatible version specified during compile configuration.

又參考博文: http://blog.csdn.net/gongchangsan/article/details/52573254
上面提示說是 CUDNN 的版本太低導緻的。我呵呵。。。

好吧,去安裝 cudnn7.5
鑒于我自己的 cuda 版本是 8.0,我下載下傳了 cudnn-8.0-linux-x64-v5.1.tgz 安裝後,還是這個鬼問題。。。。查了幾個博文,都說是 cudnn 版本太低的原因。

心塞啊,難道是沒裝上 ?
2. 如何在 Linux 系統中,隻複制檔案夾,而不拷貝檔案夾内部的檔案? 隻是檔案夾的複制。。。
答: 可以參考:http://stackoverflow.com/questions/4073969/copy-folder-structure-sans-files-from-one-location-to-another
親測有效:<code> cd /path/to/directories &&</code>

解決方法:
方法一:
假設輸入為:
model.add(ZeroPadding2D((1, 1), batch_input_shape=(1, 3, img_width, img_height)))
<code>将其改為</code><code>:</code>
model.add(ZeroPadding2D((1, 1), batch_input_shape=(1, img_width, img_height, 3)))
方法二:
在網絡層明确指明:<code>image_dim_ordering,</code><code>即輸入圖像的次元次序</code><code>;</code>
<code>例如加上如下語句</code><code>:</code>
from keras import backend as K
if K.image_dim_ordering() == 'th':
model.add(ZeroPadding2D((1, 1), batch_input_shape=(1,3,img_width, img_height)))
else:
model.add(ZeroPadding2D((1, 1), batch_input_shape=(1,img_width, img_height,3)))
<code>方法三</code><code>:</code><code>修改檔案’</code><code>~/.keras/keras.json’</code><code>中的’</code><code>tf</code><code>’</code><code>為’</code><code>th</code><code>’.</code>
