I am following the instructions in section: “AI Interaction Using GPT-40”
In sub-section: “4. Running the example”, ‘Text Communication’, I ran the following commands:

cd ~/picar-x/gpt_examples/
sudo ~/my_venv/bin/python3 gpt_car.py --keyboard

and I received the following error on the screen:
ValueError: numpy.dtype size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject

Any ideas how to fix it?
