[Bug]: Files with a "." in their directory path can't be used as dataset folders

[terrarier2111]

Describe the bug

This doesn't work and i am told, that there are no normal images detected:

Folder(
name=model_name,
root="/home/user/.config/data",
task=TaskType.CLASSIFICATION,
normal_dir="good",
abnormal_dir="bad",
image_size=(256, 256)
)

This doeswork as expected:

Folder(
name=model_name,
root="/home/user/data",
task=TaskType.CLASSIFICATION,
normal_dir="good",
abnormal_dir="bad",
image_size=(256, 256)
)

Dataset

N/A

Model

PatchCore

Steps to reproduce the behavior

Just try using a folder with a folder inside .config (i suspect this probably works with all folders that have a parent containing a "." in its name)

OS information

OS information:

• OS: Fedora Linux 40
• Python Version: 3.11

Expected behavior

The model should just accept my training images

Another consideration i had that this might also be related to hidden files/directories as .config is such a hidden directory

[alexriedel1]

Thi functionality was introduced in 69f922e but I'm not sure if it is even necessary @samet-akcay ?

[terrarier2111]

Oh okay, i see, unfortunately for me this is hindering my application, it would be nice to have any way to skip this check or forcefully allow using directories in hidden paths
