HI，I have confirmed "main.py" and "dataset path". But there is a bug happening.

[Jackyinuo]

Can you help me? or showing more detailing configs file.
Traceback (most recent call last):
File "main.py", line 15, in
loader = data.Data(args) ## data loader
File "E:\SMSR-master\data_init_.py", line 9, in init
trainset = getattr(module_train, args.data_train)(args) ## load the dataset, args.data_train is the dataset name

ZeroDivisionError: integer division or modulo by zero

Hi @Jackyinuo, sorry for the late response.
It seems the reason is that len(self.images_hr) equals 0. Please re-check the training images are correctly organized and confirm dir_data (the parent path to the folder DIV2K) is updated in option.py.

Have you slove this problem? I also have this problem.

我也遇到了上面的问题，文件目录没有放错。

已解决：
1.首先将下载下载的数据集进入DIV2K文件夹内将DIV2K_train_HR和DIV2K_train_LR_bicubic文件名改为HR和LR_bicubic
2.其次将LR_bicubic/X2,X3,X4内部的文件全部命名为与HR文件内部一样的名字，也就是说将图片名称中的x2,x3,x4全部去掉，下面我放了重命名的代码，你们可以用，注意修改路径。
3.最后将--dir_data改成你DIV2K文件前一个目录的绝对路径，就可以了

import os
import glob
from PIL import Image
file_root = r'E:\SMSR\SMSR-master\trainset\DIV2K\LR_bicubic\X2'
for root, dirs, files in os.walk(file_root):
for file in files:
srcFile = os.path.join(file_root, file)
dstFile = os.path.join(file_root, file.replace('x2', ''))
os.rename(srcFile, dstFile)
