Load the model ResNeXt-101

Hi all,
I tried to load the pre trained ResNeXt-101 model - that in this link under the title Pre-trained models. link:

I download the file ‘resnext-101-kinetics.pth’ from there drive and i’m trying to work with this net.
i wrote this line “model = torch.load(“resnext-101-kinetics.pth”)” but i think i need to define the model first and than load his parameters by this file.
I’m struggling to define the model and work with this net.

if someone did it before or know how to deal with it, it will be so helpful!
thanks!
