Simple test script rather than install

[zhu-ty]

Hi author(s), is it possible that anyone can provide a directly python mode calling script (without installing)? e.g. python main_test.py --image xxx --convert xxx, I am using a windows system where installing these module seems quite hard. However, it seems that it's possible to directly use python to call these modules (after installing all the requirements) but I am having trouble reading all these code files.
