Are there any public real-life code examples of ML applications in Python? Problems I often face at work usually differ from tutorial or book-like examples so I end up with a code that works but it's not elegant and takes too much time to write.

I wanted to ask you if there are some publicly accesible examples or repositories of Python codes that deal with machine learning development and application process but were created in a real company or organisation to develop their real-life products or services?

EDIT: What I do not think about are libraries or packages repositories such as tensorflow. I would like to see some codes of projects that for example use tensorflow to create some other product or service.
The best way is probably to Google it with "[org name] tensorflow github" and look what you get.

For instance I found:

Microsoft

Nvidia

Intel
