ValueError: num_samples should be a positive integer value, but got num_samples=0

I cannot run the QuickStart(Demo) to test the algorithm with a image in the test folder.
I put the image in the test folder(EDSR-Pytorch/test), and I run the demo.sh in the src folder
the error happen like _this:
Traceback (most recent call last): File "main.py", line 33, in <module> main() File "main.py", line 22, in main loader = data.Data(args) File "/home/liangjc/Desktop/EDSR-PyTorch/src/data/__init__.py", line 31, in __init__ num_workers=args.n_threads, File "/home/liangjc/anaconda3/lib/python3.6/site-packages/torch/utils/data/dataloader.py", line 213, in __init__ sampler = RandomSampler(dataset) File "/home/liangjc/anaconda3/lib/python3.6/site-packages/torch/utils/data/sampler.py", line 94, in __init__ "value, but got num_samples={}".format(self.num_samples)) ValueError: num_samples should be a positive integer value, but got num_samples=0
what's more, my pytorch is 1.2.0, my python is 3.6.5, I download the code directly with "git clone https://github.com/thstkgus35/EDSR-PyTorch.git "
thanks for your help

I have solved the problem. I have to uncomment the special line in the demo.sh, only in this way can I
do the test

我已经解决了这个问题。我必须取消注释demo.sh中的特殊行，只有这样才能
进行测试

I have encountered the same mistake with you. I have deleted all the # of demo. But still reported the mistake.Could you tell me how to solve it?

what do you want to do? If you only want to test pictures using the model, you should uncomment the special line which have comment said "#Test your own images". And the other lines should stay commented.
