Verifying technical requirements
All you need to take a DLI course is a web browser. DLI currently supports the most recent versions of Firefox or Chrome.
DLI courses offer the exciting oppurtunity to interact directly with a GPU for accelerated computing, deep learning, and more. To accomplish this many of the courses rely on a python technology called Jupyter Notebooks.
In order for Jupyter Notebooks to run properly you need to ensure that websockets are enabled on your network over port 80.
To test for websockets, go to websocketstest.com and verify the WebSockets (Port 80) has four green checkmarks.
If websockets do not work, try disabling your antivirus software, using a different web browser, disabling any privacy browser plugins, or using your browser in private browsing mode. VPNs have often been known to interfere with websockets. If you are still having issues try disabling/enabling your VPN.
Please note, that certain public WiFI access spots, companies, or institutions may have firewall rules in place that block websockets.
