Some problems about the environment

[wzhSteve]

Hi, I want to run the code. But I found some problems about the environment. I pipped the 'focalloss' package for both pytorch and tensorflow, but there was still an error "ModuleNotFoundError: No module named 'focalloss' ". And this problem is also happened to 'trash.load_database'.
