Running wrong with "main_prediction.py"

Hello，thank you for your share.but i encounter some problems as follows:
No such file or directory: '/with SPN/conv1/W.npy'

"self.load_weights('/Users/shashank/TensorFlow/with SPN/weights/')"
"self.sess.run(var.assign(np.load(path+var.name.split('/')[0]+'/b.npy')))"

I guess the lack of files！！！
