Thank you so much for your valuable contribution! By the way, have you tried to train any model on this dataset?

[Dominic23331]

Not yet. I'll try it in a few days。

Thank you. We shall anticipate the inclusion of the model configuration files. Moreover, it is suggested to incorporate a concise overview of this dataset, together with the file hierarchy, in the docs/en/dataset_zoo/2d_animal_keypoint.md.

I upload config files and added explanatory documents

Thanks. Have you trained models with any of them in order to verify their accuracy?

I have tried to train several classes, but the results are not very satisfactory. I will consider how to improve it.

Due to the busy work ahead, I apologize for the delay in this PR. During testing, I found that 210 epochs were not enough to fit the training set, so I increased the epochs to 300.
