Odd permissions issue on new Inky Impressions 7.3" about inky

[Sal-Tepedino]

After working with some fine folks on the Pimoroni forum, we tracked this problem down to the difference between the system install of python packages, and the user install of packages. I just didn't click in my head that there were two separate installs on the system, which might have been more obvious to me if I was a python coder.
The system install was up to date, however the user install wasn't, and when I was running the commands as myself, it was preferring the out of date user install, which cased this issue, while when running as root, it just used the system install and worked fine.

My fix was as simple as deleting ~/.local/lib/python3.9/ which caused python to use the system's install.

Though, be careful with that solution because you may have packages in the user install that you need. I initially just moved it to test if everything worked ok, and it did for me. You could also update the user packages, though my system was complaining with 'Illegal operation' errors when I tried that earlier in my troubleshooting, so this was probably the best solution for me.
