Conda install - Python3, Tensorflow, skdata - one environment

Question

I'm having a lot of trouble setting up my environment for machine learning projects on OS X Yosemite 10.10.5.

GOAL: Use skData library to get datasets, python 3 to program and use the Tensorflow library. Ultimately create an environment that has all three. (I have been using conda because I installed Anaconda and that was the recommended approach)

PROBLEM: It seems like in order to create an environment with Tensorflow, I had to use Conda, but I can only get skData using pip. When I tried conda install skdata , the terminal said

Error:  Package missing in current osx-64 channels:

pip is a package within tensor flow, so I tried using

pip install SKdata

to get the SKdata package into my python 3 tensorflow environment, but hit a wall of errors

NOTE: I get the same error when I try pip install skdata --user

My environments are setup in my anaconda folder

Answer 1

It looks like the version of skdata available from pip is only design for use with python 2. I was able to install it in an anaconda python2.7 environment without any issue but got the same error as you when trying to install it in a python 3 environment.

I was able to get it installed from the source code available here .

It requires the packages SciPy , NumPy , and SciKit-Learn in order to install. The setup will require root privileges in order to add skdata to your easy-install path. I'm not sure if this will work on macOS/OSX but on Linux the command

sudo env "PATH=$PATH" python setup.py install

will run the install with root privileges while using your user path so it gets installed in the right place. Be sure you have the anaconda environment you want to install skdata inactive when you run the command.
