A problem I faced, that the model I trained is in the non persistence storage of google colab e.g. /content/runs/detect/train2
I added this codeblook to save the trained model weights and training results in the Googledrive /content/drive/MyDrive/yolov8_training_runs/train2
import shutil
import os
# Define the source directory (output of the last training run)
source_dir = '/content/runs/detect/train2'
