bad_alloc when using Conv2d after torchvision.io.read_video

[Inforeon]

🐛 Describe the bug

Short:

Attempting a forward pass on Conv2d after loading an unrelated video with torchvision.io.read_video throws an std::bad_alloc runtime exception

Code:

import torch
import torchvision

if __name__ == '__main__':
    print(f"Pytorch Version: {torch.__version__}")
    print(f"Torchvision Version: {torchvision.__version__}")

    mp4 = torchvision.io.read_video("testpov_video.mp4", pts_unit='sec')
    print(f"Video shape: {mp4[0].shape}\tdevice: {mp4[0].device}\tdtype:{mp4[0].dtype}")

    print(f"Cuda available: {torch.cuda.is_available()}")
    print(f"Cuda device: {torch.cuda.get_device_name()}")

    test_conv = torch.nn.Conv2d(3, 8, kernel_size=1).to("cuda")
    test_in = torch.rand((1, 3, 32, 32)).to("cuda")
    test_conv(test_in)

Output

Long/Additional information:

• My system is Ubuntu 22.04.4 in a virtual machine with ~96GB ram allocated. There are 2 gpus, an A4000 and an A5000 and this error occurs when attempting to use either of them.
• The error does not occur when using the CPU
• It does not occur without loading the mp4 video
• I have tested with other mp4 files and the error still occurs
• I attempted pip install --force-reinstall torch torchvision torchaudio and the problem persisted
• I have not tested with other torchvision.io functions
