Why not train an arbitrary time model on the Septuple set of Vimeo90K, which is larger than GOPRO?
I did some tests and the arbitrary time model trained on GOPRO does not perform well.

Getting this error when running last cell in colab:

I alo had to change the name of the python file to run, to demo_2x.py, the once originally written is I believe a typo.
Thanks for your work!
I wonder if how to interpolate from 16fps to 24fps
Thanks for your wonderful work, and i want to know the meaning of Avg. flow which is written in the caption of fig6. Moreover, the last decoder results flows with the channel number of 3 in AMT-S, but in the process of visualizing optical flow, the channel number are needed to be 2, how do you deal with that?
looking forward to your reply, thanks again
thank you very much for your AMT !!!
when i run (python demos/demo_2x.py ...) , get error

I would like to know if the AMT algorithm interpolates the video by specifying the output FPS rather than by specifying the output -n value?
Very nice work!
May I know how long it costs to train the proposed method on the Vimeo dataset?
For example, with two 3090 gpus.
Bests and many thanks
Hello,
How long does it take to train the model?
Thank you
First of all, thank you for your excellent work!
While reading your paper, I noticed that you mentioned your FLOPs calculation is based on 720p frames (1280x720). I ran some tests on 720p frames using thop
, and the results I obtained were slightly different from those in your paper. I was wondering if there was any mistake in my codes:
import sys
sys.path.append('.')
import torch
import argparse
from omegaconf import OmegaConf
from thop import profile
from thop import clever_format
from utils.build_utils import build_from_cfg
parser = argparse.ArgumentParser(
prog = 'AMT',
description = 'Speed¶meter benchmark',
)
parser.add_argument('-c', '--config', default='cfgs/AMT-L.yaml')
parser.add_argument('--H', default=256, type=int)
parser.add_argument('--W', default=256, type=int)
args = parser.parse_args()
cfg_path = args.config
network_cfg = OmegaConf.load(cfg_path).network
network_name = network_cfg.name
model = build_from_cfg(network_cfg)
model = model.cuda()
model.eval()
img0_720p = torch.randn(1, 3, 720, 1280).cuda()
img1_720p = torch.randn(1, 3, 720, 1280).cuda()
embt = torch.tensor(1/2).float().view(1, 1, 1, 1).cuda()
flops, params = profile(model, inputs=(img0_720p, img1_720p, embt, True))
flops, params = clever_format([flops, params], "%.3f")
print('(THOP) 720p Flops: ', flops)
print('(THOP) 720p Params: ', params)
As a result, I got:
For AMT-S: 0.12T v.s. 0.12T in your paper
For AMT-L: 0.66T v.s. 0.58T in your paper
For AMT-G: 2.24T v.s. 2.07T in your paper
Could you please check my code for any possible mistakes? Also, do you have a FLOPs calculation code you could share? Thank you very much in advance!
Hi,
I encountered an issue when I want to prepare the optical flow data with Vimeo dataset.
Specifically, I downloaded the Vimeo dataset (vimeo_septuplet.zip) and unzipped (including rename) it as /mnt/data_nas/srwang/vimeo/vimeo_triplet/{readme.txt; sequences; tri_testlist.txt; tri_trainlist.txt}.
Following the illustration in https://github.com/MCG-NKU/AMT/blob/main/docs/develop.md to prepare the environment, I ran python flow_generation/gen_flow.py -r /mnt/data_nas/srwang/vimeo/vimeo_triplet. There is an error called "getopt.GetoptError: option -r not recognized".
The detailed snapshot for the bug is attached.
Thanks for your time and looking forward to your reply.
