Hi I am really very new at all this and I have managed to teach myself as much as i can but I have a few issues I cannot find how to fix...

First question is if i compile this as per these instructions

and then if I compile using these instructions what happens to the first compiled cec.so (or cec.py or whatever extension) file used in python?

If i run sudo pip freeze I don't see cec but if i run pip freeze i see cec==0.2.7
If I run pip show cecI get .local/lib/python2.7/site-packages as its location.
even though one of the compile output lines was Installing: /usr/local/lib/python3.7/dist-packages/cec.py
What is going on??
why is system not using new one??

That leads me on to my next question

Where does the instructions fit into the main set.

'apt-get update
apt-get install cmake libudev-dev libxrandr-dev python-dev swig
git clone https://github.com/Pulse-Eight/libcec.git
mkdir libcec/build
cd libcec/build'

Does it go here ???????

'cmake ..
make -j4
sudo make install
sudo ldconfig'

========================== Update======================

I fixed it using synaptic package manager.

1. Searched 'Pulse-Eight ' and mark for complete removal and rebooted
2. Searched 'Pulse-Eight ' and installed all packages

However I still get this error.

<module 'cec' from '/home/user/.local/lib/python3.7/site-packages/cec.cpython-37m-x86_64-linux-gnu.so'>
Traceback (most recent call last):
  File "/home/user/Documents/Python works/pyCecClient.py", line 10, in <module>
    class pyCecClient:
  File "/home/user/Documents/Python works/pyCecClient.py", line 11, in pyCecClient
    cecconfig = cec.libcec_configuration()
AttributeError: module 'cec' has no attribute 'libcec_configuration'

How do i fix it ?????????????
