Hi Isuru,
I am on a Windows 10 with Python 2.7.12, Anaconda 4.3.9 (64-bit) and trying
to install symengine using:
conda install python-symengine -c symengine -c conda-forge
And I get the following error in the command prompt:
UnsatisfiableError: The following specifications were found to be in
conflict:
- python 2.7*
- python-symengine -> python 3.5*
Use "conda info <package>" to see the dependencies for each package.
Any ideas what the problem might be? As another data point, when trying pip
install symengine I get:
Collecting symengine

Thanks for any help on this. I did make sure CMake is installed, so I'm not
sure what the CMake errors are all about.
