How do I correct my mistakes and the next step？

2.I ran the following command under git-bash ：sudo CUDA_VISIBLE_DEVICES=0 sh ./scripts/alvlm/main.sh caltech-101 vit_32 random 0 AS
The cloned library is the latest commit
3.I've changed the location
In the process of recoding，I put the101_ObjectCategories and split_zhou_Caltech101.json in caltech-101 as requested,then I put caltech-101 into configs/datasets/,I add the PATH: "C:\\Users\\86187\\Desktop\\source\\py\\CV\\DA\\pcb\\configs\\datasets\\caltech-101"
in DATASET of caltech-101.yaml.
In caltech101.py,I changed this line of code self.image_dir = os.path.join(self.dataset_dir, "101_ObjectCategories") to something like this: self.image_dir = cfg.DATASET.PATH.
In main.sh,I changed this line of code DATA=/go/to/data # YOU NEED TO FIX IT to something like this: DATA=C:/Users/86187/Desktop/source/py/CV/DA/pcb/configs/datasets/caltech-101
4. I think possible bugs
Some files or subdirectories in the caltech-101 dataset may be missing or paths misconfigured or self.image_dir may be configured as an invalid or non-existent path, causing problems with dataset loading.

First, thank you for your interest in my work! I think this can be caused from file existence problem.

In our code, you should download split_zhou_Caltech101.json from this link and put it under $DATA/caltech-101.

If you already downloaded above file, I recommend you to follow the dataset.md step by step.

Thank you!
