ImportError: No module named yapsy.PluginManager

abhijith · November 2018

I am using OpenBCI - Python in my Ubuntu 18.04

I tried to run the below code for communicating the device through terminal

sudo python user.py -p /dev/ttyUSB0

But it shows the error -

> Traceback (most recent call last):

> File "user.py", line 12, in <module>

> from yapsy.PluginManager import PluginManager

> ImportError: No module named yapsy.PluginManager

I tried to install yapsy after that also the same error is showing. If I use the code without sudo, then it shows like

> serial.serialutil.SerialException: [Errno 13] could not open port /dev/ttyUSB0: [Errno 13] Permission denied: '/dev/ttyUSB0'

Thats why I used the sudo command.

Kindly help me in solving this error and to run the module using python

What OpenBCI device are you using? Cyton or Ganglion? Ganglion does not use serial ports.

Does your device work with the OpenBCI_GUI?

@wjcroft

I am using cyton board with 8 electrodes and It is working finely with GUI. What should I do?

Try 'pip install yapsy'

Also, if you are on Windows try to run as administrator, otherwise try the sudo command.
