There are some omissions in the environment configuration and codes:

[huzimun]

1. there are two other dependencies are also needed: nltk=3.8.1, scipy
2. in files 'referenced_images/objects/target_object.txt' and 'referenced_images/style/target_style.txt', the paths of reference images are absolute in your machine, may they be changed to relative paths, such as "./referenced_images/style/watercolor"
3. in line 11 of IQA.py, "from test_style import metric" raises an error "ModuleNotFoundError: No module named 'test_style'". I guess the name of the "test_style" module is changed.
