How to install gi for anaconda python3.6

in Ubuntu 16.04 I have python2.7, python3.5 and python3.6. Anaconda is using python3.6. I can import gi on 2.7 and 3.5, but I can't in 3.6. I created the link as suggested here but I still get an error.

I have had the very same problem today and what worked for me is the following:

First, create the link, as suggested in the stackoverflow post you cited (assuming that anaconda is installed under /home/your_user/anaconda3)

ln -s /usr/lib/python3/dist-packages/gi /home/your_user/anaconda3/lib/python3.6/site-packages/

Secondly, navigate into the gi folder that you just linked, within your anaconda directory and rename a copy of the two .so files to fit the python-version of anaconda (in my case from 3.4 to 3.6)

cd /home/your_user/anaconda3/lib/python3.6/site-packages/gi/
sudo cp _gi.cpython-34m-x86_64-linux-gnu.so _gi.cpython-36m-x86_64-linux-gnu.so

and

sudo cp _gi_cairo.cpython-34m-x86_64-linux-gnu.so _gi_cairo.cpython-36m-x86_64-linux-gnu.so

Finally, the import gi worked accordingly within my anaconda environment.
