License of pretrained weights for research

I have a question regarding the license of pretrained weights available under torchvision.models and their usage for research purposes. The git repository includes the license that regulate the usage of scripts. However, there is no license associated with the pretrained weights that are available for download. I would like to inquire whether the same license apply to these pretrained weights and am I permitted to use those weights in my research. It would be a great help to hear your response on this regard.
