No dataset_spec file found in directory

[RongKaiWeskerMA]

I was trying to run the code, but I got the No dataset_spec file found in directory error. I pass the directory where it stores all the converted datasets (ilsvrc_2021/aircraft./...) into the bash file. It seems it directly look for the .json file each dataset. But the json files is each subfolder of the converted datasets folder. Do I need to move all the json files out, or I pass each dataset directory separately during training?
