libtorrent version (or branch): 1.2.0 / boost 1.75.0

platform/architecture: RHEL 9.0

We upgraded libtorent from 1.1.5 to 1.2.0 and boost from 1.65.1 to 1.75.0. The prodcution code is failing when trying to use the function set_settings.
The codeblock below gives an idea of instrcutions we are using in the production code.

>>> 'set_settings' in dir(a_session)
False

>>> quit()

Is there an api change in the libtorrent python binding for libtorrent.session ? Please suggest I am unable to find it from a quick search.

If yes, then what to use instead?

If not, then how to debug this?

Thanks!

Reading the doc

You have some control over session configuration through the session::apply_settings() member function. To change one or more configuration options, create a settings_pack object and fill it with the settings to be set and pass it in to session::apply_settings().

I think I need to use session.apply_settings(). but it says I need to create a settings_pack object ? I am unable to do that.

What I did is as follows

settings = session.get_settings()
setttings[key1] = value1
.
.
.
session.apply_settings(settings)

Please suggest whether the above is correct or not.
