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.
