Hello:
I am trying to use theano with GPU on Ubuntu. I am getting some weird
errors that I can't solve.using theano 0.8.2, python 2.7. cndnn v5, CUDA 8.0
The code will print a long code and print the next two error:
1.
/usr/bin/ld: cannot find -lcudnn
collect2: error: ld returned 1 exit status
I have export LD_LIBRARY_PATH in ~/.bashrc file. and there are the .so file
in the path.
2.

I see someone said that theano cache is corrupt,delete it.But I cannot run
theano-cache clear successfully , the two errors above continue appear.
Thanks in advance. Looking forward to your reply.
