I am unable to import sqlalchemy. I searched and found few solutions like installing flask or flask_sqlalchemy etc. None of these helped.
What am I missing?

Try `pip --version` what does it say? You might have to use `pip3` instead. – vallentin Apr 19 '17 at 11:20

pip 9.0.1 from /usr/local/lib/python3.4/site-packages (python 3.4). I did try pip3 as well. No luck. – Arvind Kandaswamy Apr 19 '17 at 11:28

Sometimes, you need to restart ipython for it to find freshly-installed modules.
I believe this holds for modules that add to sys.path.
As per Can I zip all the python standard libs and the python still able to import it? , site.main() should work, too.
It, among other things, scans site-packages directories for .pth files and adds their contents to sys.path. Thanks to the fact that its logic checks for duplicates before adding, it shouldn't clutter sys.path when invoked repeatedly.

@ArvindKandaswamy how do you do that? I see http://stackoverflow.com/questions/26603456/reset-ipython-kernel but it has no definite answer. – ivan_pozdeev Apr 22 '17 at 15:45

1I did it within jupyter by selecting kernel->restart from the jupyter menu. – Arvind Kandaswamy Apr 24 '17 at 00:29
