theano gives “…Waiting for existing lock by unknown process…”

Question

My code was working fine. However, now I am getting an error that says:

Using gpu device 0: GeForce GT 750M
WARNING (theano.gof.cmodule): ModuleCache.refresh() Found key without dll in cache, deleting it. /Users/mas/.theano/compiledir_Darwin-14.5.0-x86_64-i386-64bit-i386-2.7.10-64/tmpcm9_P6/key.pkl
INFO (theano.gof.compilelock): Waiting for existing lock by unknown process (I am process '2799')
INFO (theano.gof.compilelock): To manually release the lock, delete /Users/mas/.theano/compiledir_Darwin-14.5.0-x86_64-i386-64bit-i386-2.7.10-64/lock_dir

I delete the folder lock_dir, but I still get the same message.

I solved this problem by adding the following code to my ~/.theanorc :

[global]
base_compiledir=/tmp/%(user)s/theano.NOBACKUP
