The setting of .val_mask data for data.x[data.val_mask] is not explicitly shown in the code.

I encountered a similar issue while running the train_img function, and it seems to be related to the version of torch_geometric. Although I tried various versions of torch_geometric, the problem persisted. Interestingly, the function works when applying SiGra on the entire DLPFC dataset, but the issue arises when applying SiGra to other datasets.

Therefore, I commented out the code in train_transformer.py because I believe that the train_img function is intended to work exclusively with the DLPFC dataset, which contains Ground Truth, as shown in the picture.

SiGra is an excellent method for spatial domain analysis. Could the authors provide a tutorial on how to apply SiGra to the 10x dataset that lacks manual annotation?
