        joblib.dump(rf_model, 'model_rf.pkl', protocol=2)

Useful Stuffs

• Check ip address
  • sudo ifconfig
• .BASHRC AND .BASH_ALIASES
  • i.e. alias python=/usr/local/bin/python2.7 to reset python to use Python 2.7 Source
  • Check version locations with these commands (using Python 2.7.13 as example) Source
