Correction: the OS version is actually:  _Ubuntu 20.04.2 LTS_. ---

You have tried to use the function `.arrowkdb.tb.prettyPrintTableFromTable` and received the error `'.arrowkdb.tb.prettyPrintTableFromTable`. In kdb this means the variable does not exist:   q)doesNotExist[1] 'doesNotExist [0] doesNotExist[1]   This suggests you have yet to load the library. Either pass it to the command line `q arrowkdb.q` or load it in your running session `q)\l arrowkdb.q`   ---
