[python] Cannot import keras after installation

I'm trying to setup keras deep learning library for Python3.5 on Ubuntu 16.04 LTS and use Tensorflow as a backend. I have Python2.7 and Python3.5 installed. I have installed Anaconda and with help of it Tensorflow, numpy, scipy, pyyaml. Afterwards I have installed keras with command

sudo python setup.py install

Although I can see /usr/local/lib/python3.5/dist-packages/Keras-1.1.0-py3.5.egg directory, I cannot use keras library. When I try to import it in python it says

ImportError: No module named 'keras'

I have tried to install keras usingpip3, but got the same result.

What am I doing wrong? Any Ideas?

Firstly checked the list of installed Python packages by:

pip list | grep -i keras

If there is keras shown then install it by:

pip install keras --upgrade --log ./pip-keras.log

now check the log, if there is any pending dependencies are present, it will affect your installation. So remove dependencies and then again install it.

Ran to the same issue, Assuming your using anaconda3 and your using a venv with >= python=3.6:

python -m pip install keras
sudo python -m pip install --user tensorflow

I had pip referring by default to pip3, which made me download the libs for python3. On the contrary I launched the shell as python (which opened python 2) and the library wasn't installed there obviously.

Once I matched the names pip3 -> python3, pip -> python (2) all worked.
