osc_tools.py not found

[bugith]

Hi
Ubuntu 24.04
Following README, I installed requirements.txt this way:

pip3 install virtualenv ==>>ERROR
sudo apt install python3-pip  ==>>ok
pip3 install virtualenv==>>ERROR
sudo apt install python3-virtualenv  ==>>ok
virtualenv -p python3 .   ==>>ok
source bin/activate   ==>>ok
pip3 install -r requirements.txt   ==>>ok

My ~/bin was filled with garbage so I removed all and re-run:

virtualenv -p python3 bin/kartaview  ==>>ok
source bin/kartaview/bin/activate  ==>>ok

Now I want to send pictures to kartaview there is nothing like osc_tools in my laptop, sudo find / -iname osc_tool* gives nothing so I don't know were the '/path_to_scripts/osc_tools' is.

python: can't open file '/home/me/bin/kartaview/osc_tools.py': [Errno 2] No such file or directory
sudo find / -iname osc*
echo $?
0

What is wrong please, I understand nothing to python.
