Use absolute path for images

[moshanATucsd]

Hi,

It seems that I have to put images to demo folder in order to do inference. If I use an absolute path for the images stored not in the occlusion net directory, check path existence always fails, even though the url is exactly the path of the image.

I am wondering how could we use a path eg /home/user/image.png directly, instead of in demo folder?

I forget that we are using docker, so we should load the image dir first
