The error message you're encountering suggests that the version of Python you're using doesn't support the `annotations` feature in the `__future__` module. The `annotations` feature was introduced in Python 3.7, and it allows type hints to be stored as strings in the function/class definition itself rather than in a separate stub file. It seems like you are running your code on Python 3.6 or an older version, which does not recognize this particular future import. To resolve the issue: 1. Upgrade your Python installation to version 3.7 or later. 2. If you can't upgrade your Python version for some reason, you might need to find an earlier version of the `smart_open` library that is compatible with your current Python version. You can specify the version in your requirements.txt file or when installing via pip: ``` pip install smart_open==<compatible_version> ``` Remember to replace `<compatible_version>` with the specific version that supports your Python 3.6 environment.
