Installing RDKit

I have installed Spyder3.2.1 in the current version of Miniconda3 on my Debian v-9.1.0 64 bit Linux platform. Spyder is performing well, but I am having difficulty installing the RDKit.

I followed the directions in the RDKit_Docs_current.pdf:

How to install RDKit with Conda

Creating a new conda environment with the RDKit installed using these packages requires one single command similar to the following:

$ conda create -c rdkit -n my-rdkit-env rdkit

Finally, the new environment must be activated, so that the corresponding python interpreter becomes available in the same shell:

$ source activate my-rdkit-env

There were no warning or error messages during the installation, but when I attempt running a simple Python script:

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

from __future__ import print_function
from rdkit import Chem

m = Chem.MolFromSmiles('Cc1ccccc1')
m

I get:

ModuleNotFoundError: No module named 'rdkit'

RDKit is installed in ~/miniconda3/envs/mr-rdkit-env

Unfortunately, I have no clue as to what the problem(s) may be, assistance will be much appreciated.

Thanks in advance.
