the model named with _ar
means training with AR and with a basic pretrained model.
for example, pwclite_ar.tar
is trained on Sintel training set with pwclite_raw.tar
as the pretrained model(which is trained from scratch on raw videos and not used AR in the pre-training stage).

Thank you for the reply.
I tested Sintel's pwclite_ar.tar
on the training set. The results look much worse than the numbers reported in Table 1 in the paper. If I understand correctly, pwclite_ar.tar
is the one fine-tuned on the training set and should match the one used in Table 1. Did I miss something? Thank you.

Can you tell me what result did you get?
I run the command
python3 train.py -c configs/sintel_ft.json -m checkpoints/Sintel/pwclite_ar.tar -e
and get the results same as the paper
* Epoch 1 EPE_0: 2.79 EPE_1: 3.73
from arflow.
What I got are * Epoch 1 EPE_0: 4.20 EPE_1: 5.19
.
I am using PyTorch 1.6.0. Not sure if this causes the difference.

Hi @playerkk,
I tested it in PyTorch 1.6 and found that the problem was caused by the default behavior of align_corners
for grid_sample
has changed to False since PyTorch 1.3.0.
Specify align_corners=True
in utils/warp_utils.py and you will get the correct results.
from arflow.
After fixing the issue, I can reproduce the numbers. Thanks for the help.
from arflow.
I got these two numbers : 3.20 and 4.23 not the same as yours, when I tried to add align_corners=True I got this error
im1_recons = nn.functional.grid_sample(x, v_grid, mode=mode, padding_mode=pad,align_corners=True)
TypeError: grid_sample() got an unexpected keyword argument 'align_corners
from arflow.
