Are you sure you have a Reachy 2023? (–> Which Reachy model do I own? (2019, 2021 or 2023))
Usually we already install the pycoral library on Reachys 2023 but maybe we miss to do that on yours, sorry about that. We made a Notion page with each command that we run to install pycoral on Python 3.10, the commands are taken from an issue on the pycoral repository, let us know if this works!
