When I try to import psycopg2 it show below log for me:

Traceback (most recent call last):
  File "D:/Desktop/learn/python/webcatch/appserver/testpgsql.py", line 2, in <module>
    import psycopg2
  File "D:/Desktop/learn/python/webcatch/appserver/webcatch/lib/site-packages/psycopg2-2.6.1-py3.5-win32.egg/psycopg2/__init__.py", line 50, in <module>
    from psycopg2._psycopg import BINARY, NUMBER, STRING, DATETIME, ROWID
ImportError: No module named 'psycopg2._psycopg'

How can I solve it? My platform is win10 (64) and version is python 3.5

Eureka! I pulled my hair out for 2 days trying to get this to work. Enlightenment came from this SO Question. Simply stated, you probably installed psycopg2 x64 version like I did, not realizing your python version was 32-bit. Unistall your current psycopg2, then:

Download: psycopg2-2.6.1.win32-py3.4-pg9.4.4-release.exe from HERE, then run the following in a Terminal:

C:\path\to\project> easy_install /path/to/psycopg2-2.6.1.win32-py3.4-pg9.4.4-release.exe
C:\path\to\project> python manage.py makemigrations
C:\path\to\project> python manage.py migrate

You may also need to (re)create super user with:

C:\path\to\project> python manage.py createsuperuser
