Something weird happening with the tox environment and the mvtec path

[jpcbertoldo]

Describe the bug

While trying to run pytest locally i ran into a problem related to the paths inside mvtec.

To Reproduce

I ran pytest using the tox environment locally on the branch main with

# in the anomalib root
tox -e pre_merge_pytest tests/pre_merge/utils/callbacks/visualizer_callback/test_visualizer.py

With the env var ANOMALIB_DATASET_PATH:

ANOMALIB_DATASET_PATH=".../datasets/MVTec"  # "..." is just a simplification
# i also tried
# ANOMALIB_DATASET_PATH=".../datasets/MVTec/bottle"

and got

FAILED tests/pre_merge/utils/callbacks/visualizer_callback/test_visualizer.py::test_add_images[segmentation] - cv2.error: OpenCV(4.5.5) /io/opencv/modules/imgproc/src/color.cpp:182: error: (-215:Assertion failed) !_src.empty() in function 'cvtColor'

in the logs i can see

------------------------------------------------------------------------------------ Captured stderr call ------------------------------------------------------------------------------------
[ WARN:[email protected]] global /io/opencv/modules/imgcodecs/src/loadsave.cpp (239) findDecoder imread_('/cluster/CMM/home/jcasagrandebertoldo/repos/anomalib-workspace/data/cuda/datasets/MVTec/bottle/broken_large/000.png'): can't open/read file: check file path/integrity

and

E       cv2.error: OpenCV(4.5.5) /io/opencv/modules/imgproc/src/color.cpp:182: error: (-215:Assertion failed) !_src.empty() in function 'cvtColor'

Expected behavior

It should be properly finding mvtec's dr.
