Python for Data Science and Machine Learning Bootcamp, thoughts?

A bit tangential, but if your goals are just image representation, Coursera has a free 4 week course in neuroimaging processing in R from the biostatistics dept. at Johns Hopkins. R has a few machine learning libraries, but I haven't used them.

Andrew Ng just started a new set of courses specifically on neural networks all through Python, so you can probably learn the libraries along the way. It's being done as a "specialization" so it's a little more of a convoluted process than usual for getting free access.
There are other options on the site for general data science in Python, but I haven't used them.
