can't use cpu,maybe something wrong in config.py

[leonyan18]

in my opinion，I think maybe there is some problem in CRSLab/crslab/config/config.py 37
# gpu
os.environ['CUDA_VISIBLE_DEVICES'] = gpu
self.opt['gpu'] = [i for i in range(len(gpu.split(',')))]
if gpu=-1，self.opt['gpu'] will be [0]

Thanks for your feedback. We have fixed this problem by considering the CPU training case separately, now you can try again.
