Installing and using iPython

new

[4.Feb.2016]: iPython is now jupyter: http://ipython.org/

• to install jupyter (on MacOSX): see documentation : here http://jupyter.readthedocs.org/en/latest/install.html
  • install anaconda from http://www.continuum.io/downloads#_macosx
  • reboot mac
  • in terminal: conda install jupyter
• start iPython/Jupyter:
  • in terminal jupyter notebook
• note, there are also additional jupyter kernels for other languages such as IDL, PhP, Javascript, Scilab, http://github.com/ipython/ipython/wiki/IPython-kernels-for-other-languages

Btw. after starting I got an UTF-8 error when calling pandas, i.e.

jupyter ValueError: unknown locale: UTF-8

The key was here to enter in the console the following lines:

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

• for installing iPython see here: http://ipython.org/ipython-doc/2/install/install.html
• start iPython notebook, run in a normal terminal

  ipython notebook --pylab inline

• for the command line version on Ubuntu go to the menu and start development>ipython
• run the code with <shift+enter>
• updating pandas (I had 0.7 installed but needed 0.9 for doing some str ops) simply type sudo pip install --upgrade pandas

ToDo

• General: iPyhton scripts and tutorials, on data analysis, machine learning, etc: http://github.com/ipython/ipython/wiki/A-gallery-of-interesting-IPython-Notebooks#earth-science-and-geo-spatial-data
• check out GeoPandas (perhaps pysal) : http://github.com/geopandas/geopandas
• iPython Notebooks for Earth & GeoSciences: http://github.com/ipython/ipython/wiki/A-gallery-of-interesting-IPython-Notebooks#earth-science-and-geo-spatial-data
  • EarthPy: http://earthpy.org/
  • find graffiti near subway entrances: http://nbviewer.jupyter.org/github/invisibleroads/crosscompute-tutorials/blob/master/computational-analysis/300%20Count%20graffiti%20sightings%20within%20100%20feet%20of%20a%20subway%20entrance.ipynb
