Does AppDaemon cache libraries

Does appdaemon cache libraries it’s already used once? I just downloaded an updated to a library I am using, installed it using pip but appdaemon is still reporting an error at the same line of code in the library that it was yesterday. I checked the source for the library and in the new release, that line is a comment. If it does cache the library, how do I clear it? Do I just have to restart it?

A restart should fix it yes.
