I'm executing bellow command in Mac (High Sierra) as a part of getting started with pyAudioAnalysis.

pip install numpy matplotlib scipy sklearn hmmlearn simplejson eyed3 pydub  

I'm getting following error during the installation process. Appreciate your input.

matplotlib 1.3.1 has requirement numpy>=1.5, but you'll have numpy 1.8.0rc1 which is incompatible.

Please find more information below,

I was able to solve this with @Jacob's solution with some additional steps. I'll post it here for anyone else facing this.

1. Firstly as Jacob mentioned I downloaded and installed the latest Python 2.7.14+.

2. Executed sudo easy_install pip to install pip again

3. Executed sudo pip install numpy
