Hi,
I am following this tutorial for running YOLO v8 to detect and automatically identify number plates from a video. I am currently on, 30:02 time in the video, where he runs the code successfully. However, my code brings the following error:
Traceback (most recent call last): File "/home/pi/yolotest.py", line 3, in <module> from sort.sort import * File "/home/pi/sort/sort.py", line 23, in <module> matplotlib.use('TkAgg') File "/home/pi/env/lib/python3.11/site-packages/matplotlib/__init__.py", line 1255, in use plt.switch_backend(name) File "/home/pi/env/lib/python3.11/site-packages/matplotlib/pyplot.py", line 415, in switch_backend module = backend_registry.load_backend_module(newbackend) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/pi/env/lib/python3.11/site-packages/matplotlib/backends/registry.py", line 323, in load_backend_module return importlib.import_module(module_name) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.11/importlib/__init__.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/pi/env/lib/python3.11/site-packages/matplotlib/backends/backend_tkagg.py", line 1, in <module> from . import _backend_tk File "/home/pi/env/lib/python3.11/site-packages/matplotlib/backends/_backend_tk.py", line 16, in <module> from PIL import Image, ImageTk ImportError: cannot import name 'ImageTk' from 'PIL' (/usr/lib/python3/dist-packages/PIL/__init__.py)

Note that I am using a Raspberry Pi 5 4 GB RAM running Raspberry Pi OS 64-bit. Along with that, all the system packages and libraries(including sort folder downloaded) are in a python virtual environment. Please help.
