Hello! It looks like you encountered an AttributeError
because the method you're trying to use isn't available in the Pose
class of YOLOv8m-pose.
For the pose estimation model, you should use the .predict()
method instead of .detect()
which is typically used with detection models. From the snippets you've shown, it appears you're using .predict()
correctly. However, to avoid any possible errors, ensure all your syntax matches exactly as it should be when employing the .predict()
method.
Here's a simple usage example:
results = model.predict(frame)
keypoints = results[0].keypoints.xy.cpu().numpy()
Ensure your installation is updated and correctly configured, particularly if transitioning between different environments like VS Code and Google Colab that might have different package versions.
If issues persist, verifying paths and ensuring that your environment aligns with the requirements of the Ultralytics library could help pinpoint discrepancies. If still unresolved, please provide further details or the specific line that continues to raise errors.
Thank you for reaching out!

@glenn-jocher OK, I tried changing the code to yours, but the error persists:
results = model.predict(frame)
kps = results[0].keypoints.xy.cpu().numpy()

AttributeError: 'Pose' object has no attribute 'detect'
from ultralytics.
Hello! It looks like there's a mix-up with the methods in use. The error 'Pose' object has no attribute 'detect'
suggests trying to access functionality that doesn't exist in the pose estimation model.
Here's how you should configure your predictor:
results = model.predict(frame) # Correct method for prediction
keypoints = results[0].keypoints.xy.cpu().numpy() # Extracting keypoints
Ensure your model instantiation (YOLO('path_to_model')
) is correctly referenced to the model you intend to use and that it's appropriately configured for pose detection, not object detection.
If the problem persists and all setups look correct, it might help to reinstall the Ultralytics library to ensure there are no corrupted or mismatched files. 👍 Let us know how it goes!
from ultralytics.
This may be due to inconsistencies between the version of Ultralytics used for inference and the version of Ultralytics used for training
from ultralytics.
Hello! It sounds like you might be right about the version inconsistency. Please make sure that both the training and inference environments are using the same version of Ultralytics YOLO. You can check the version in your environment with:
pip show ultralytics
If they differ, consider updating to the latest version using:
pip install --upgrade ultralytics
This should help maintain compatibility across your processes. Let us know how it goes! 😊

Good afternoon! Yes, I already realized that the problem was in the version update ultralytics :)
Thank u!
