AttributeError: 'module' object has no attribute 'cuda'

Question

I was trying to run this repository: https://github.com/WaqasSultani/AnomalyDetectionCVPR2018 In the Test_Anomaly_Detector_public.py I am stuck with error:theano.sandbox.cuda.use('gpu0') AttributeError: 'module' object has no attribute 'cuda'. I am using theano as backend

This is Test_Anomaly_Detector_public.py:

You can comment out this line. When you run please follow this

THEANO_FLAGS=mode=FAST_RUN,device=cuda0,floatX=float32 python [...]
