example for noobs...

I apologize for the bad translation (google translator).
I use venv (otherwise linux does not allow installing anything with python)
I activate vnv and run vnom installation pip install NodeGraphQt
then I install pip3 install PyQt5

I unzip "NodeGraphQt-main.zip"

python examples/basic_example.py
Traceback (most recent call last):
File "/home/zweistein/test_grap/NodeGraphQt-main/examples/basic_example.py", line 9, in
from examples.nodes import basic_nodes, custom_ports_node, group_node, widget_nodes
ModuleNotFoundError: No module named 'examples'

I copy basic_example.py to the NodeGraphQt-main folder

python basic_example.py

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: type object 'QGraphicsItem' has no attribute 'DeviceCoordinateCache'

What am I doing wrong?
