Has anyone run into this issue when trying to run
flow.visualize()

pip install prefect[viz]
but am still getting this:

try installing it
Copy code
sudo apt-get --reinstall xdg-utils
ohh you’re on Amazon Linux… try with
yum install xdg-utils

You may need to contact AWS support about the best way to install xdg-utils on Amazon Linux, from a quick search it looks like you’d need to add external repos.
