I tried to install the retinaface-pytorch module and execute the sample code provided there. But I run into the following error :
>>> model = get_model("resnet50_2020-07-20", max_size=2048)
Traceback (most recent call last):

I do not understand this message. Any suggestions as to what I could do now, would be really appreciated.
