Question

I used the the follow yaml and used the coco8-pose.yaml,when exit then click train->ultraly will close the window,show "KeyError: 'pose'“ error in cmd. I think is yaml not correct, can u provide the correct yaml file. thks!
yaml:
nc: 1
kpt_shape: [17, 3]
flip_idx: [0, 1, 2]
names:
0: mouse

Keypoint names per class

kpt_names:
0:
- center
- nose
- tailhead

that is all error info:

Hi @goldenzjy2023, thanks for reaching out! It seems you're running into a KeyError when trying to configure pose training with Ultralytics. I understand this can be a bit frustrating.

For Ultralytics Pose tasks within X-AnyLabeling, you'll actually need to provide two separate configuration files in the 'Config Tab'.

First, there's the Data configuration, which defines your dataset. For this, you can refer to the official Ultralytics documentation for their dataset YAML structure. A good example to start with is their coco8-pose.yaml file:
👉 https://github.com/ultralytics/ultralytics/blob/main/ultralytics/cfg/datasets/coco8-pose.yaml

Additionally, you'll need a specific Pose Config file. This file contains keypoint names and other pose-related settings that X-AnyLabeling uses. You can find an example tailored for X-AnyLabeling here:
👉 https://github.com/CVHub520/X-AnyLabeling/blob/main/assets/yolov8_pose.yaml

We understand that having two separate configuration files for pose training can be a bit confusing for users. This is a historical design choice, and while we'd love to streamline this experience, we currently don't have the resources to optimize it. We appreciate your understanding and support!

Let us know if these examples help you get started. Happy labeling! 😊

thank u answer my question! I used u support fomatter config file also same error。and I exchange that config error again. data config: [cid:bda00aca-8db4-4e53-b1d1-cc2b0b8743b8] pose config: [cid:cb39877f-e8af-4975-a4eb-d8a2816f6d70] [cid:3340f246-7c3d-4756-9db5-1545cbcd55ff]

Hi @goldenzjy2023,

Good news! We've identified and resolved the KeyError: 'pose' you were encountering. This was due to an internal handling issue with how the pose configuration was processed.

Could you please pull the latest changes from the main branch? This update should address the problem, allowing your training to proceed smoothly.

We apologize for the inconvenience and appreciate your patience as we worked through this! Please let us know if you have any further questions or if the issue persists after updating. Happy labeling! 😊
