Question

I am new to Python. I am trying to use Graphlab create launcher to import Graphlab libraries in my python notebook. I already have Anaconda installed on my MacBook Pro(OSX).

When I start to run Graphlab create launcher, I get following error,

UnsatisfiableError: The following specifications were found to be in conflict:
  - conda 4.0.8* -> conda-env <2.5 -> python 2.7*

Use "conda info <package>" to see the dependencies for each package.

You can find the detail of the log at https://github.com/jaysara/Python-ML/blob/master/launcher-install-log.txt

Can anyone help, why am I getting this error ?

Answer 1

You will have to first install latest update of anaconda and then install graphlab. The best way to use graphlab is using a Virtual env that I guess you are using. You may try in your terminal

conda update conda

To first get latest anaconda that may support graphlab. You may like to read the documentation on Graphlab how to create virtual env and install graphlab to correct if you have done any mistake : Link

Answer 2

I was having problems with: conda install -y -c bioconda cwltool

I solved it by : conda config --add channels conda-forge

the package (cwltool) I was trying to install could not solve dependencies that where satisfied in a different channel
