It appears as though helper_types is not included in the types file in the v0.5.4 tag, but exists in main

          Oh, it looks like `helper_types` is not included in the types file:

cannot import name 'helper_types' from 'google.generativeai.types' (/opt/venv/lib/python3.10/site-packages/google/generativeai/types/__init__.py)

Please note that the main branch is unstable. helper_types was added in #297 which was post v0.5.4. This should be available in future releases.

refer to the change-log here:
v0.5.4...main

I see that #341 is in that release. I was trying to use that feature, which appears to require helper_types.
