Installation problem: cannot import name from 'paperqa'

[bsvisser]

Sorry for the (hopefully) simple question - I'm trying to install paper-qa using mamba and it's giving me an error of not being able to import names. Trying to run the example:

from paperqa import Settings, ask

answer = ask(
    "What manufacturing challenges are unique to bispecific antibodies?",
    settings=Settings(temperature=0.5, paper_directory="my_papers"),
)

Returns: ImportError: cannot import name 'Settings' from 'paperqa' (C:\Users\b\mambaforge\envs\py311\Lib\site-packages\paperqa\__init__.py)

What could cause this error? Thank you for any help in advance.

Hey @bsvisser 👋, I'm here to help you with any bugs, questions, or contributions. Let's figure this out together!

The ImportError: cannot import name 'Settings' from 'paperqa' could be caused by a circular import issue or a missing import statement. In the paperqa/settings.py file, the Settings class is defined, but there is no explicit import statement for Settings within the same module.

To resolve this, ensure that the Settings class is correctly imported if it is defined in another module, or verify that there are no circular import issues. Here is the relevant part of the code where Settings is defined:

class Settings(BaseSettings):
    model_config = SettingsConfigDict(extra="ignore")

And the function that uses Settings:

def get_settings(config_or_name: MaybeSettings = None) -> Settings:
    if isinstance(config_or_name, Settings):
        return config_or_name
    if config_or_name is None:
        return Settings()
    return Settings.from_name(config_name=config_or_name)

Make sure that the Settings class is accessible from where you are trying to import it. If Settings is defined in paperqa/settings.py, you should be able to import it directly:

from paperqa.settings import Settings

If the issue persists, check for any circular dependencies that might be causing the import to fail ^[1].

Hi @bsvisser , can you please give us the output of pip list? I am thinking you don't have paper-qa version 5, likely you have v4. The Settings object is new in that version.

So you'll want to do something like pip install paper-qa>=5. Please let us know how this turns out
