Question about "07-CSRNet_all_ep_39_mae_32.6.pth"

[JayzWho]

Excuse me, I have a problem that is recently I've been going through some old codes of a senior student and I came cross settings of "07-CSRNet_all_ep_39_mae_32.6.pth" which I haven't found. I tried to replace it with our trained model of CSRNet on SHTech-B which is a "PartBBest.pth.tar". The results were that the pre-train model had some mis-matched factors and it failed when loading with
"RuntimeError: Error(s) in loading state_dict for WeakNetwork: Missing key(s) in state_dict: "frontend.0.weight", "frontend.0.bias", "frontend.2.weight", "frontend.2.bias", "frontend.5.weight", "frontend.5.bias", "frontend.7.weight", "frontend.7.bias", "frontend.10.weight", "frontend.10.bias", "frontend.12.weight", "frontend.12.bias", "frontend.14.weight", "frontend.14.bias", "frontend.17.weight", "frontend.17.bias", "frontend.19.weight", "frontend.19.bias", "frontend.21.weight", "frontend.21.bias", "backend.0.weight", "backend.0.bias", "backend.2.weight", "backend.2.bias", "backend.4.weight", "backend.4.bias", "backend.6.weight", "backend.6.bias", "backend.8.weight", "backend.8.bias", "backend.10.weight", "backend.10.bias", "output.weight", "output.bias". Unexpected key(s) in state_dict: ""."

My question is: First, where can I get the "07-CSRNet_all_ep_39_mae_32.6.pth" file? Is it an open source file that can be directly downloaded or is it a result of running through a model?
Second, I think our own "pth.tar" was supposed to work, since it's just a pre-trained CSRNet that's required. Are the runtime error of missing factors not its fault? If so, how can I make changes to solve this mismatch? Thank you.
