Hopefully you are using conda environments and not virtual envs, but whenever 
this happens to me it’s because I forgot to install Jupyter in the new 
environment, so when I invoke Jupyter from the command line it uses the one in 
the default conda environment.

Test for this: check that you have Jupyter installed and are using the right 
one (“which jupyter”)

In addition I have an older rdkit version installed in a virtual env called 

Now, when I run a jupyter notebook in the 092017 env and display the rdkit 
version it still says 092016.

Does anybody have an idea what is going on?

Many thanks in advance,
