To Reproduce
Steps to reproduce the behavior:
import torchvision
data = torchvision.datasets.VOCDetection('datasets/', year='2007', image_set='train', download=True, transform=None,target_transform=None, transforms=None)
Expected behavior
The dataset should be downloaded.
Environment
The information below relates to the local configuration. For Google Colab I did not examine the environment, I just ran the two commands above.
- PyTorch / torchvision Version (e.g., 1.6 / 0.7.0):
- OS (e.g., Linux): Ubuntu 20.04
- How you installed PyTorch / torchvision (
conda,pip, source): Conda - Build command you used (if compiling from source):
- Python version: 3.7
- CUDA/cuDNN version: 10.2
Additional context
Tested locally and in Google Colab. I also tried downloading MNIST via torchvision.datasets and it worked.
