Step 5: Detecting Objects in Images with YOLOv8 @FlyingTeller meaning it seems to forget the classes that the pre-trained model was trained on. Activate Virtual Environment: Unix/macOS: ('yolov8n. So for example, the original model would detect lots of faces in a particular model and then once I trained on my new dataset, it would not detect those same faces. The export step you've done is correct, but double-check if there's a more efficient model variant suitable for your use case. Always try to get an input size with a ratio # Run YOLOv8 to detect objects in a web cam don't do this yet, # we still need to do a bit more. It is the 8th and latest iteration of the YOLO (You Only Look Once) series of models from Ultralytics, and like the other iterations uses a convolutional neural network (CNN) to predict object classes and their bounding boxes.
