FileNotFoundError: [Errno 2] No such file or directory: '../data/tiny_images.bin'

[siryul]

When i was running python main.py --dataset cifar10 --imb_type exp --imb_factor 0.01 --alg open -p 100 --lambda_o 1 -ab 512 --gpu_str 'cpu', there occurs an errors: FileNotFoundError: [Errno 2] No such file or directory: '../data/tiny_images.bin', please tell me what is this, and how to solve it? Thanks :）The follow is the error info:
