Hi! Thanks for sharing your excellent work. I am very interested in it. @Etienne-Meunier
But when executing the training command(python3 model_train.py --path_save_model train_me --base_dir /home/fxx/data/DAVIS-data --data_file DataSplit_me/DAVIS_D16Split ), some errors occurred.
It seems that there was a hyperparameter storage error when saving the model. I have tried many methods like pytorch/pytorch#78720 and Lightning-AI/pytorch-lightning#9318 , but cannot solve it.
The default DAVIS dataset is used, and the body of the code has not been changed. Does anyone encounter this problem or know how to solve it?

Hi! Thanks for sharing your excellent work.
Could you help me with training and evaluating your method under the setting of K>2?
Hi, I see that the released checkpoint is for binary motion segmentation only, however, your paper states that the results improve as you increase the number of motions (K). I wonder if there is a way I can run your code to verify this? How can I verify the improved results by increasing K?
