    "In this notebook, we discuss how to install the Anaconda distribution of Python and other applications you need to run do development in Python, which will be useful for doing financial analysis in Python with libraries like finmarketpy. You can also down a lot of this material from https://github.com/cuemacro/teaching - in particular the scripts for installing the conda environments. We'll also be installing a lot of other useful libraries for machine learning, natural language processing etc. We'll also make other suggestions so you can do financial data analysis, such as making sure that your firewalls allow access to sites like Quandl."

Once you've done that you can edit the scripts below where indicated, so the GPU enabled Python versions of PyTorch and TensorFlow are installed (rather than the CPU version). Note, the CPU versions work fine, but will be slower! If you are running on the cloud, you need to check that the cloud machine you are using has a GPU. Typically free instances are CPU only."

You can configure the machine as want, and the configuration will be stored for as long as you have the instance. Do make sure to power down the machine, once you are finished using it.
