YOLOv8 is built against NumPy 1.24.x, and newer versions (1.26.4) cause a “dtype size changed” error. Adding: !pip uninstall -y numpy !pip install numpy==1.24.3 at the top of train-yolov8-object-detection-on-custom-dataset.ipynb fixes that.

Description
Pinned NumPy to version 1.24.3 to fix a compatibility issue with YOLOv8 in Google Colab. Colab’s default NumPy version (1.26.4) causes a ValueError: numpy.dtype size changed when importing YOLOv8 models built against NumPy 1.24.x.
Dependency:
numpy==1.24.3
