Error: with open(txt_path,'r') as f: FileNotFoundError: [Errno 2] No such file or directory:

When doing deep learning today, the following error occurred:

root='G:/anaconda/pythonProject2/DATA/HWDB1'transform = transforms.Compose([transforms.Resize((64,64)),transforms.ToTensor(),transforms.Grayscale()])# read training settrain_dataset =Mydataset(root+'/train.txt',num_class=10,transforms=transform)

with open(txt_path,'r') as f: FileNotFoundError: [Errno 2] No such file or directory: 'G:\anaconda\pythonProject2\HWDB1/train.txt'
The reason is that trainThe contents of the .txt file format are as follows: ./DATA/HWDB1/train\00000\100234.png.
The file name of the HWDB1 dataset is HWDB1, so the absolute path becomes G:/anaconda/pythonProject2/HWDB1/HWDB1, which naturally cannot be found.
So just rename the folder HWDB1 to DATA and make the path name G:\anaconda\pythonProject2\DATA\HWDB1.
