I have Donkeycar running on a Pi4, have captured data and successfully trained pilots on an Ubuntu workstation. When I put the pilots back on the Pi and run the Donkeycar code with the suggested command it fails with this error: “OSError: Unable to open file (file signature not found)”.

I have a script that is trying to save numpy arrays to an hd5 file one by one. For every array I create a new dataset with the index.
