Hi there @thompsondavid478
Are you running this on the standard Virtual Machine running Ubuntu 18.04 with the recommended software versions? I only ask because there are many different software packages that interplay to create a working simulated drone environment, and as new versions come out- things break everywhere. But with the current advised software versions the environment has been confirmed to work.
Additionally, it appears python3 is being referenced in the error output, but for now the course has been using python2.
