🐞 Can't run the 'getting_started' notebook

[Abecadarian]

Describe the bug

I've just started learning how to use anomalib and tried to run the '001_getting_started' notebook. It's completely impossible.

When I try to run it in Colab, I get a bunch of errors:

datamodule = MVTec('sample_data')
datamodule.prepare_data()  # Downloads the dataset if it's not in the specified `root` directory
datamodule.setup()  # Create train/val/test/prediction sets.

i, data = next(enumerate(datamodule.val_dataloader()))
print(data.keys())

mvtec: 5.26GB [04:23, 20.0MB/s]

ValueError Traceback (most recent call last)

----> 3 datamodule.setup() # Create train/val/test/prediction sets.

5 i, data = next(enumerate(datamodule.val_dataloader()))

I tried to run it locally on my computer instead, and that ran into more errors - when I tried to install anomalib using pypi, several of the modules couldn't be found:

ImportError: cannot import name 'ExportType' from 'anomalib.deploy'

And it couldn't load the MVTec dataset:

TypeError: MVTec.init() missing 2 required positional arguments: 'root' and 'category'

When I tried to install anomalib from source, I got this error:

ModuleNotFoundError: No module named 'openvino.tools.mo'

Hi @Abecadarian,

I tried it out myself and indeed there are some complications with running it on colab.

My solution:
Before executing 'Install from source' block, add the following line:
%cd /root

I.e. it should look like this:

%cd /root
!git clone https://github.com/openvinotoolkit/anomalib.git
%cd anomalib
%pip install .

Alternatively the issue should also be solved by setting
datamodule = MVTec(root="/root")

Also it might be helpful to add %pip install GitPython infront of the "verifying the working directory"-block.

I think the reason why the pypy install doesn't work correctly is that the latest version there is still v0.7.
This is then locally and on colab an issue.

Regarding the errors you are getting when you try to install it locally from source I'm not quite sure, maybe you can provide further information about the error-log if this ist still relevant for you.

Best regards.

@NilsB98, you are right! Due to the security scans, we had to add validate_path function to input paths. But the current version fails, when the input path is outside the home directory.

anomalib/src/anomalib/data/image/mvtec.py

Line 131 in b5ceacf

root = validate_path(root)

anomalib/src/anomalib/data/utils/path.py

Lines 214 to 230 in b5ceacf

	# Check if the resolved path is within the base directory
	if not str(path).startswith(str(base_dir)):
	msg = "Access denied: Path is outside the allowed directory"
	raise ValueError(msg)
	# In case path ``should_exist``, the path is valid, and should be
	# checked for read and execute permissions.
	if should_exist:
	# Check if the path exists
	if not path.exists():
	msg = f"Path does not exist: {path}"
	raise FileNotFoundError(msg)
	# Check the read and execute permissions
	if not (os.access(path, os.R_OK) or os.access(path, os.X_OK)):
	msg = f"Read or execute permissions denied for the path: {path}"
	raise PermissionError(msg)

This may not be the best approach though since the data can be on a mount. I'll see how we can ease this security check.

@samet-akcay I am running the notebook on my C drive and getting the same issue - Has there been a resolution to this?
