Colaboratory is a Chrome App developed by a joint team consisting of Google Research, Matthew Turk, and the IPython/Jupyter. It works like a Jupyter notebook. Colaboratory merges many open source packages with Google technologies which facilitates collaboration and reduces the burden of setting up the working environment.

To check what packages Colaboratory has, I have done a simple test by importing packages. Here is what I found.

Data Processing Packages. Four commonly used data processing/analysis packages like numpy and pandas come in handy

• Pandas
• Numpy
• Scipy
• Statsmodels

Visualization Packages. I have tested four packages and three of them are available. The one tested but not found is Bokeh.

• matplotlib
• seaborn
• plotly

Machine Learning Packages. I have tested five common python machine learning packages and two of them are available. Theano, Caffe and XGBoost are not available.

• sklearn
• tensorflow

Image Processing Packages. Two packages Pillow and Skimage are available. OpenCV, one of my favorite packages is not available.

• Pillow
• Skimage

Natural Language Processing Packages. Only NLTK was tested and it is available.

Packages do not exist

• OpenCV
• Bokeh
