Multiple errors from code example in Datasets doc page #79
Description
Hi. I'm excited to try this but having trouble with the instructions. Taking the code from the page: https://salu133445.github.io/muspy/datasets/index.html
Even just the top part:
import muspy
# Download and extract the dataset
nes = muspy.NESMusicDatabase("data/nes/", download_and_extract=True)Results in the error:

mkdir -p /content/data/nesand then re-run that code, then we get a new errors:
