X3D Video on RGB Video

[MoH-assan]

Hi, Thanks for the Repo

I am trying to use GradCAM on the X3D model from the tutorial below. https://pytorch.org/hub/facebookresearch_pytorchvideo_x3d/#define-input-transform

However, I am getting the error below. Which I guess has to do with upsampling the GCAM to the original input size.
I am not sure if the upsampling should also get updated after this merge https://github.com/jacobgil/pytorch-grad-cam/pull/466?

Thanks,

target_layers = [model.blocks[4]]
#print(f'target_layers: {target_layers}\n \n \n')

cam = GradCAM(model=model, target_layers=target_layers)
#print(f'model: {model}')

input_tensor= inputs[None, ...] #input_tensor shape: torch.Size([1, 3, 13, 182, 182])
print(f'input_tensor shape: {input_tensor.shape}\n \n \n')
grayscale_cam = cam(input_tensor=input_tensor)#, targets=targets)

input_tensor shape: torch.Size([1, 3, 13, 182, 182])
