unmatched iekfnets.p from dropbox

[enguang2]

Hello, The iekfnets.p file downloaded from wget "https://www.dropbox.com/s/77kq4s7ziyvsrmi/temp.zip" does not correspond with the MesNet structure. The fourth layer has different size and apparently the iekfnets.p contains more layes than the 8 layes' MesNet we see in utils_torch_filter.py

I've met the same problem! as followings:

RuntimeError: Error(s) in loading state_dict for TORCHIEKF: Unexpected key(s) in state_dict: "mes_net.cov_net.8.weight", "mes_net.cov_net.8.bias", "mes_net.cov_net.12.weight", "mes_net.cov_net.12.bias", "mes_net.cov_net.16.weight", "mes_net.cov_net.16.bias". size mismatch for mes_net.cov_net.4.weight: copying a param with shape torch.Size([64, 32, 5]) from checkpoint, the shape in current model is torch.Size([32, 32, 5]). size mismatch for mes_net.cov_net.4.bias: copying a param with shape torch.Size([64]) from checkpoint, the shape in current model is torch.Size([32]).

In debugging, ipdb> mondict.keys() odict_keys(['initprocesscov_net.factor_initial_covariance.weight', 'initprocesscov_net.factor_process_covariance.weight', 'mes_net.cov_net.0.weight', 'mes_net.cov_net.0.bias', 'mes_net.cov_net.4.weight', 'mes_net.cov_net.4.bias', 'mes_net.cov_net.8.weight', 'mes_net.cov_net.8.bias', 'mes_net.cov_net.12.weight', 'mes_net.cov_net.12.bias', 'mes_net.cov_net.16.weight', 'mes_net.cov_net.16.bias', 'mes_net.cov_lin.0.weight', 'mes_net.cov_lin.0.bias'])

@ccsmm78 I would guess the URL points to the parameter file hasn't been updated and the parameter file actually has been altered since firstly published. Nevertheless, I am trying to train the model locally yet the training stops at early epoch(7 epoch), have you encountered same case? :)

[Mieczmik]

@enguang2 I have the same problem. I will give info about progress later.

[Akudavale]

hello EVERYONE,

II am facing same issuee of size mismatch how to resolve it?

[TiloccaS]

hi @Mieczmik @enguang2 I noticed that I have the same problem as yours, have you solved it somehow, or there are news?

[luopengting]

I have fixed the problem, please see #88 , hope it will help you. :D @Akudavale @TiloccaS
