/home/ssf/.conda/envs/geotransformer/lib/python3.8/site-packages/sklearn/metrics/_classification.py:1245: UndefinedMetricWarning: Precision and F-score are ill-defined and being set to 0.0 due to no predicted samples. Use zero_division parameter to control this behavior.

Will this warning have an effect on training results?

Hi, I'm also experiencing this problem and my training loss stays at 0. Have you solved it yet?

Hi there,
I'm currently exploring the model and I've encountered an issue: the links to download the data and weights files seem to be unavailable. If you happen to have these files, could you please share them with me at 2373178085@qq.com? I'd greatly appreciate your assistance. Thank you so much!!

Hello, I encountered a FileNotFoundError after running: [Errno 2] No such file or directory: 'snapshot/indoor/est_traj/3DMatch/250/7-scenes-redkitchen/est.log'， There should be no predicted samples. If you have, please send a snapshot to my email: 2373178085@qq.com
