为什么 glob.glob 返回一个空列表？

Question

Please i need help. I am using windows. I am getting an empty list when I run this glob code. my ipynb file is inside the code folder, and I have 4 different folders inside the train and test folders that serve as labels for my image task.

# Setup train and testing paths
train_dir = "code/Datasets/train/**/*.jpg"
test_dir = "code/Datasets/test/**/*.jpg"

train_dir, test_dir

check = glob.glob(train_dir)
print(check)

I also tried pasting some images to enable me try this and it did not work

train_dir = "code/Datasets/train/*.jpg"

Two possible issues:

1. When you use ** in your glob path, you fail to pass recursive=True , so it won't actually treat ** as special
2. Add import os , print(os.getcwd()) . Is your working directory the one that contains code/Datasets/... ? Relative paths like this require a specific working directory (separate from the script directory). If you were expecting it to use the script directory, you need to specify your path relative to __file__ , eg train_dir = os.path.join(__file__, "code/Datasets/train/**/*.jpg")
