which one is the checkpoint?

[tangyuelm]

Thanks for your codes and model. I want to download the i3d model pre-trained on the Kinetics dataset but feel confused about the checkpoint. I followed the path in evaluate_sample.py
_CHECKPOINT_PATHS = {
'rgb': 'data/checkpoints/rgb_scratch/model.ckpt',
'rgb600': 'data/checkpoints/rgb_scratch_kin600/model.ckpt',
'flow': 'data/checkpoints/flow_scratch/model.ckpt',
'rgb_imagenet': 'data/checkpoints/rgb_imagenet/model.ckpt',
'flow_imagenet': 'data/checkpoints/flow_imagenet/model.ckpt',
}
I copied the checkpoints folder to a new path and tried to load it.
However, is seems that no such file or directory: 'checkpoints/rgb_scratch_kin600/model.ckpt'
I found 4 files under the folder rgb_scratch_kin600 but cannot find the model.ckpt. Could anyone help me?
Besides, can the checkpoint be loaded to model writing in Pytorch?

To my understand, the rgb_scratch_600 means the checkpoints for RGB frames pre-trained on Kinetics-600. What do the folder rgb_scratch and flow_scratch mean?
Besides, in each folder, there are four files called "checkpoints", "model.ckpt.data-00000-of-00001", "model.ckpt.index", "model.ckpt.meta", but there is no file called model.ckpt. Which one should I use?
I am not familiar with Tensorflow, so I am wondering how to load these checkpoints in Pytorch. Do you have the .pth version for the checkpoint pre-trained on Kinetics-400? I can only find the checkpoints pre-trained on ImageNet and Charades in your Pytorch codes from https://github.com/piergiaj/pytorch-i3d, but I believe Kinetics-400 is more commonly used for pre-training.

I am also looking for same answer. Or any way to convert them to .h5 format?

Sorry for the long delay. rgb_scratch means model trained from scratch on pixels (RGB values). From scratch as opposed, to from ImageNet-pretrained weights. Flow_scratch means models trained from scratch on optical flow. I'm not familiar with Pytorch either... i'm sure there are Pytorch checkpoints on the web, though. Best, Joao

Sorry, I'm not entirely sure about PyTorch. Do look online for Pytorch checkpoints, there should be some available. Best, Joao

@joaoluiscarreira thank you so much. Is there any command line with which I can input the mp4 and get back the logits and features? or do I have to export flow and frames for the input in model to get these.

is there the pytorch version of i3d? https://github.com/piergiaj/pytorch-i3d

[joaoluiscarreira]

Hi, scratch means trained from scratch, without imagenet pretraining. For tensorflow inference I'd recommend loading models from tf-hub as that's more user friendly. This repository is a bit old unfortunately. There are several pytorch versions of i3d, if you google around. Best, Joao
