serial.py - sys.argv[1] index out of range

[Schmalvis]

I feel I must be doing something wrong here in executing the python script to pick-up the raw audio and send to a file. Have been following the detailed write-up for realtime ML audio suppression on Pico 2 in Magpi #146. However am hitting the same error here regardless of IDE or OS (tired on Windows 11 in VSCode and RPI5 w/ Geany, Thonny and VSCode).
Pyserial lib is installed in both cases. Debug shows nothing in sys.argv array

File "/home/pi/Workspace/rnnoise-examples-for-pico-2/examples/serial/serial_denoise.py", line 10, in
port = sys.argv[1]
IndexError: list index out of range

hi @Schmalvis,

Could you please share the full command you are running?

[Schmalvis]

this is probably where I'm going wrong. I'm not running a command, just 'running' the script via the IDE

[sandeepmistry]

Ok, the script expects three arguments: the serial port, the input file path, and the output file path

[Schmalvis]

ah ok, gotcha. I'm a complete newbie to this; was just following along with the magazine article trying to learn something new :)
