1. Check failed: s.ok() could not find cudnnCreate in cudnn DSO;

参考了博文:http://blog.csdn.net/jk123vip/article/details/50361951
下载了 cudnn-6.5-linux-x64-v2.tgz 并且按照上面说的安装完毕后,发现,原本的错误是没了,但是有了新的错误提示:
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.
F tensorflow/core/kernels/conv_ops.cc:532] Check failed: stream->parent()->GetConvolveAlgorithms(&algorithms)

又参考博文: http://blog.csdn.net/gongchangsan/article/details/52573254
上面提示说是 CUDNN 的版本太低导致的。我呵呵。。。
好吧,去安装 cudnn7.5
鉴于我自己的 cuda 版本是 8.0,我下载了 cudnn-8.0-linux-x64-v5.1.tgz 安装后,还是这个鬼问题。。。。查了几个博文,都说是 cudnn 版本太低的原因。

心塞啊,难道是没装上 ?
2. 如何在 Linux 系统中,只复制文件夹,而不拷贝文件夹内部的文件? 只是文件夹的复制。。。
答: 可以参考:http://stackoverflow.com/questions/4073969/copy-folder-structure-sans-files-from-one-location-to-another
亲测有效: cd /path/to/directories &&
find . -type d -exec mkdir -p -- /path/to/backup/{} \;
即:进入你想复制的文件夹内部,然后执行
find . -type d -exec mkdir -p -- /你想拷贝的文件路径/{} \;
就这样,就完毕了。。。
3. Keras VGG16中ValueError: filter must not be larger than the input问题的解决
the solutions are learning from http://blog.csdn.net/u013920434/article/details/53443757
解决方法:
方法一:
假设输入为:
- model.add(ZeroPadding2D((1, 1), batch_input_shape=(1, 3, img_width, img_height)))
将其改为
:
- model.add(ZeroPadding2D((1, 1), batch_input_shape=(1, img_width, img_height, 3)))
方法二:
在网络层明确指明:image_dim_ordering,
即输入图像的维度次序
;
例如加上如下语句
:
- 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)))
方法三
:
修改文件’
~/.keras/keras.json’
中的’
tf
’
为’
th
’.
