🐛 Describe the bug

VOCtrainval_25-May-2011.tar downloaded with VOCSegmentation() and VOCDetection() is extracted to data/ as TrainVal/VOCdevkit/VOC2011/ but not to data/VOCdevkit/ as VOC2011/ as shown below, then TrainVal/VOCdevkit/VOC2011 is loaded from data/. *Other zip files are properly extracted to and loaded from data/VOCdevkit/:

from torchvision import datasets

train_data = datasets.VOCSegmentation(
    root="data",
    year="2011",
    image_set="trainval",
    download=True,
)

from torchvision import datasets

train_data = datasets.VOCDetection(
    root="data",
    year="2011",
    image_set="trainval",
    download=True,
)

data
 |-VOCdevkit
 |  |-VOC2007
 |  |-VOC2008
 |  |-VOC2009
 |  |-VOC2010
 |  └-VOC2012
 └-TrainVal # Here
    └-VOCdevkit
       └-VOC2011

In addition, I moved VOC2011/ from data/TrainVal/VOCdevkit/ to data/VOCdevkit/, then it was not loaded:

data

Hi @hyperkai ,

Sorry, I'm not sure I completely follow here. It's possible that different datasets download the data in different places (even in some unexpected cases).

Is anything broken, or is it just that you would have expected some files to be downloaded somewhere else?
