Python cec Errors

[mtullo27]

When running the sample code located here, I get the following errors.

<module 'cec' from '/home/mtullo/.local/lib/python3.9/site-packages/cec.cpython-39-arm-linux-gnueabihf.so'>
Traceback (most recent call last):
  File "/home/mtullo/Desktop/tulloVision.py", line 38, in <module>
    class pyCecClient:
  File "/home/mtullo/Desktop/tulloVision.py", line 39, in pyCecClient
    cecconfig = cec.libcec_configuration()
AttributeError: module 'cec' has no attribute 'libcec_configuration'

Most probably you have python-cec installed with pip (this lib https://github.com/trainman419/python-cec). Both this lib and python-cec unfortunately have "cec" as module name, so they conflict. I suggest you to run "pip uninstall cec".

After ensure libcec python is the only package:

$ python

I conclude the script is wrong:

+from cec import cec

 class pyCecClient:
   cecconfig = cec.libcec_configuration()

For me it needs to use sudo but now it works

$ sudo ./pyCecClient.py
