问题
I get the following deprecation warning when saving/loading a gensim word embedding:
model.save("mymodel.model")
/home/.../lib/python3.7/site-packages/smart_open/smart_open_lib.py:398:
UserWarning: This function is deprecated, use smart_open.open instead.
See the migration notes for details:
https://github.com/RaRe-Technologies/smart_open/blob/master/README.rst#migrating-to-the-new-open-function
'See the migration notes for details: %s' % _MIGRATION_NOTES_URL
I don't understand what to do following the notes on the page. So, how should I save and open my models instead?
I use python 3.7 , gensim 3.7.3. and smart_open 1.8.4. I think I did not get the warning when using gensim 3.7.1. and python 3.5. smart_open should have been 1.8.4.

You can ignore most "deprecation warnings", as they're just an advisory about underlying changes that for now still work, but there's a new preferred way to do things that may be required in the future.
In this case, the warning is about a function inside the smart_open package that the gensim package is using. That is, it's not the .save() you are calling that's deprecated, but something inside .save(). The gensim authors will eventually update .save() to use the newly-preferred variant of what smart_open offers.
You can just keep using .save(), ignoring the message as long as things still work for you – unless you'd like to contribute the fix to .save() to remove the warning to gensim. (It may, however, have already been fixed in the development code, to become available in the next gensim release.)
