 - **Workshop Contents**: Introduction to a new remote module called [otbtf](https://github.com/remicres/otbtf) enabling the use of deep learning techniques with real world geospatial data. This remote module uses the high performance numerical computation library TensorFlow to bring the deep learning magic into OTB. How to train and apply deep nets to Remote Sensing images? We will see how to do it on various THEIA images.
 
-- **Workshop Requirements**: Oracle Virtualbox (download [here](https://www.virtualbox.org/). We will work on a Ubuntu virtual machine that includes the whole already-installed stuff. Familiar with command line is a prerequisite. A bit of knowledge of Python would be better, but not mandatory. Minimum hardware configuration: 16Gb RAM but 32Gb would be great as the VM will be hosted on your computer. For this session, feel free to come with your own data (images, terrain truth, etc.).
