That's because its inspiration was to create a language with the power of Erlang but that was as enjoyable to code in as Ruby (many people's "most fun to code in" language if they've actually worked with it; unfortunately it can't compete with Python's ecosystem).
Erlang and Elixir have a pretty good interop with Python through Erlport. It's not a deep language-level integration (as in, inheriting modules from Python classes or something like that), but it implements a binary message format Erlang nodes use to communicate and offers an API for IPC with Python on top of that. It's not for all use cases, but I had great success deploying a fleet of Raspberries for home automation using nothing but Ansible, Elixir, and Python. Elixir would handle distribution and manage messaging between nodes and local Python processes, while Python scripts would control peripherals. I stopped developing it since I moved to a smaller place, but I firmly believe Elixir+Python is a great solution for anything distributed that would benefit from the Python ecosystem.
