Perfect.
that was the "problem" no comment about myself
Thank you very much György

Hi everyone
I have a "silly" problem.
I'm beginning the Python programming in Onion Omega2
That's my program lines, just like the help says

import onionGpio
pin13 = onionGpio.onionGpio(13)

the "program" breaks here with the message
AttributeError: 'module' object has no attribute 'onionGpio'

Of course I have installing the module like the manual explains, without errors

opkg update
opkg install python-light pyOnionGpio

The error is not only writing with a text editor but in the Python command line
I also updated firmware and restart

What is happening?
Thanks
