ERRORS in code about lapsrn HOT 5 CLOSED

Which system do you use? Could you check is your "vllab_dag_loss.m" copied to matconvnet/matlab/+dagnn properly? If not, you have to manually copy it. Some people report that the copy command in MATLAB does not work on Window 10.

My system is ubuntu 14.04. The environment is matlab R2015b + CUDA8.0.
My matconvnet is installed in this path /usr/local/MATLAB/R2015b/toolbox/Matconvnet/matconvnet-1.0-beta24. I have tried install.m and is successful. I also tried copy "vllab_dag_loss.m" to matconvnet/matlab/+dagnn. But it just can not found this object. The errors are like this:

demo_LapSRN

Thank you for your help. @phoenix104104

You should copy vllab_dag_loss.m to your own MatConvNet path. In your case, it's
/usr/local/MATLAB/R2015b/toolbox/Matconvnet/matconvnet-1.0-beta24/matlab/+dagnn

Sure. I have copied this file to this path many times and use 'vl_compilenn('enableGPu', true);' to compile.
But I still have this error when I run 'demo_LapSRN.m' and 'train_LapSRN.m'.
I have tried to Change permissions of this file in 777. But it still can not run.

Thanks a lot. I reboot my system and make it again. It's run !
