Im working on PyCharm, on terminal installed via pip olimex and jupyter, then run jupyter notebook and bokeh server first I listed the serial ports and got '/dev/ttyACM0', the I did "from olimex.nb import exg; exg('/dev/ttyACM0')" but got the following error. Any ideas what could go wrong? thank you very much. The port isnt being used by any other app and everyting is running on a PyCharm terminal.
