Error running demo of IAM script about returnn HOT 3 CLOSED

The main error, which is partly crippled in your output, is this:

/usr/bin/ld: ne peut trouver -lcudnn
collect2: error: ld returned 1 exit status

This means, it did not found cuDNN.

from returnn.

You need to set some environment variables, so it can correctly link to cudnn.
You can try to put something like this (for your version of cudnn and your username and location of cudnn) into your ~/.bashrc (assuming that the .so files are in /home/voigtlaender/cudnn_v5/)

#cuddn v5.1
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/voigtlaender/cudnn_v5/
export LIBRARY_PATH=$LIBRARY_PATH:/home/voigtlaender/cudnn_v5/
export CPATH=$CPATH:/home/voigtlaender/cudnn_v5/

from returnn.

Thank you for your responses, it is working now.

from returnn.
