[requests] How to get rid of duplicate cookies?

Question

Python

Library used: requests
Creating a session: Making session = requests.Session()
some requests. I save cookies to a file like this:

pickle.dumps(requests.utils.dict_from_cookiejar(session.cookies))

In another script, I also create a session, load from a cookie file like this:

cookies = requests.utils.cookiejar_from_dict(pickle.loads(DATA_FROM_FILE))

and I set their sessions: session.cookies = cookies
After I make several requests, a miracle happens. If the response to the request contains a Set-Cookie and the key already exists, then it is added again. Calculate the reason. Those cookies that I load from the file do not belong to the domain, and those that come from Set-Cookie belong to the domain to which the request is made.
How to get rid of duplicate cookies? Maybe somehow you can save cookies with belonging to the domain?
