have problem in trainDAN.py

你好，我在运行python trainDAN.py，会出现以下错误：
Traceback (most recent call last): │
File "trainDAN.py", line 12, in │
trainSet = ImageServer.Load(datasetDir + "dataset_nimgs=40_perturbations=[0.2, 0.2, 20,│
0.25]_size=[112, 112].npz") │
File "/home/zhanggl/dantf/DAN-TF/ImageServer.py", line 31, in Load │
arrays = np.load(filename) │

line 415, in load │
fid = open(os_fspath(file), "rb") │
FileNotFoundError: [Errno 2] No such file or directory: '../data/dataset_nimgs=40_perturbat│
ions=[0.2, 0.2, 20, 0.25]_size=[112, 112].npz'

请问这是我哪里出来问题？（我已经过运行TestSetPreparation.py 和 TrainingSetPreparation.py）
非常感谢。
