问题
I need to have Theano operate on my Mac for a school project. I downloaded sources from here (first line of the table) and put the untared file in the repertory of my school project. I didn't know if this was sufficient, so I also used pip install Theano. Everything seems fine since I got this :
You are using pip version 6.1.1, however version 7.0.0 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Requirement already satisfied (use --upgrade to upgrade): Theano in ./anaconda/lib/python2.7/site-packages/Theano-0.7.0-py2.7.egg
Requirement already satisfied (use --upgrade to upgrade): numpy>=1.6.2 in ./anaconda/lib/python2.7/site-packages (from Theano)
Requirement already satisfied (use --upgrade to upgrade): scipy>=0.11 in ./anaconda/lib/python2.7/site-packages (from Theano)
As you can see, I'm using Anaconda.
However, when I run a test in a python console, I get theses messages :
>>> import theano
WARNING (theano.configdefaults): g++ not detected ! Theano will be unable to execute optimized C-implementations (for both CPU and GPU) and will default to Python implementations. Performance will be severely degraded. To remove this warning, set Theano flags cxx to an empty string.
>>> theano.test()

Is there any problem ? Are Theano and its compiler well installed ? I tried the first example of this tutorial and had the same results without any bugs. But I'm wondering if there will be any bugs if I use more sophisticated functions and classes.
