How to find user id from session_data from django_session table?

In django_session table session_data is stored which is first pickled using pickle module of Python and then encoded in base64 by using base64 module of Python.

I got the decoded pickled session_data.

session_data from django_session table:

after decoding it by base64.decode(session_data):

 \x80\x02}q\x01(U\x0f_session_expiryq\x02K\x00U\x12_auth_user_backendq\x03U)django.contrib.auth.backends.ModelBackendq\x04U\r_auth_user_idq\x05\x8a\x01\x02u.bfe09a19b4a6d7c44761ecf49d54b3ad

I want to find out the value of auth_user_id from auth_user_idq\x05\x8a\x01\x02u.
