"RuntimeError: Found 0 files in subfolders of ".. 关于 Pytorch 中的子文件夹的错误 [英] "RuntimeError: Found 0 files in subfolders of ".. Error about subfolder in Pytorch

问题描述

我目前基于 Window 10、Jupyter Notebook、Pytorch 1.0、Python 3.6.x.

I'm based on Window 10, Jupyter Notebook, Pytorch 1.0, Python 3.6.x currently.

首先我使用此代码确认文件的正确路径:print(os.listdir('./Dataset/images/')).

At first I confirm to the correct path of files using this code : print(os.listdir('./Dataset/images/')).

我可以检查这条路径是否正确.

and I could check that this path is correct.

但我遇到了错误:

运行时错误:在以下子文件夹中找到 0 个文件:./Dataset/images/支持的扩展名有:.jpg、.jpeg、.png、.ppm、.bmp、.pgm、.tif"

RuntimeError: Found 0 files in subfolders of: ./Dataset/images/ Supported extensions are: .jpg,.jpeg,.png,.ppm,.bmp,.pgm,.tif"

怎么了?你能提出一个解决方案吗?

What is the matter? Could you suggest a solution?

我尝试了 ./dataset/1/images 喜欢这种方法.但结果是一样的....

I tried to ./dataset/1/images like this method. but the result was same....

img_dir = './Dataset/images/'
img_data = torchvision.datasets.ImageFolder(os.path.join(img_dir), transforms.Compose([
            transforms.Scale(256),
            transforms.RandomResizedCrop(224),
            transforms.RandomHorizontalFlip(),
            transforms.ToTensor(),
            ]))
img_batch = data.DataLoader(img_data, batch_size=batch_size,
                               shuffle = True, drop_last=True)

推荐答案

你能把你的文件结构贴出来吗?在你的情况下，它应该是:

Can you post the structure of your files? In your case, it is supposed to be:

img_dir
|_class1
  |_a.jpg
  |_b.jpg
|_class2
  |_a.jpg
  |_b.jpg
...
