How can I implement the global_drop_path?

[wspba]

Hi, I conducted some experiments on cifar-10 dataset, and I only used the local_drop_path, I've tried lots of drop_path_ratio and dropout_ratio, the full-net's result was closed to yours , but the results of single columns were Not as satisfactory as expected. Was this owing to the global_drop_path which I didn't use? If so, how can I implement this global_drop_path? I'm not quite sure about the meaning of 'tying the weight'.
Hope to hear from you soon, thx!
