Hi,

We found a workaround to unblock this issue.
Please use basic cudnnConvolutionForward algorithm instead.

1. Download source

wget http://dlib.net/files/dlib-19.16.tar.bz2
tar jxvf dlib-19.16.tar.bz2

2. Apply this changes:

diff --git a/dlib/cuda/cudnn_dlibapi.cpp b/dlib/cuda/cudnn_dlibapi.cpp

                         context(),
                         descriptor(data),

3. Build and install

mkdir build
cd build
cmake ..
cmake --build .
sudo python setup.py install

Our internal team keep checking the cuDNN issue and will let you know if any progress.
Thanks.
