@sarthakpati Testing is getting the error
FileNotFoundError: File not found: "/home/runner/work/GaNDLF/GaNDLF/testing/data_output/histo_patches/histo_patches_output/1/image/image_patch_2624-2304.png" for the test case testing/test_full.py::test_train_segmentation_rad_2d. Any insights on how should this be fixed?
