Hi! Sorry you were having problems – in some cases, the prodigy command does’t seem to be recognised correctly, so the easiest solution is to simply prefix it with python -m, for example:
python -m prodigy dataset my_set
See this thread for more details. If you want a shorter command, you can always create your own alias that maps prodigy=python -m prodigy (or pgy or any other command you like).
