Correct the relative path and switch to the CPU.

Question:
when I run demo.py

indexnet_matting/scripts/demo.py

Line 45 in 867720d

checkpoint = torch.load(RESTORE_FROM)

Error will be reported when loading the model.

Reason
The relative path of pretrained and example is wrong.

My GPU is GTX 950M.
The memory is too small and needs to be switched to the CPU to predict.

indexnet_matting/scripts/demo.py

Line 45 in 867720d

checkpoint = torch.load(RESTORE_FROM)

change to:
checkpoint = torch.load(RESTORE_FROM, map_location='cpu')

indexnet_matting/scripts/demo.py

Line 91 in 867720d

inputs = inputs.cuda()

change to:
inputs = inputs.cpu()
