Ego4d_NLQ_2022_1st_Place_Solution

The 1st place solution of 2022 Ego4d Natural Language Queries. For more details, please refer to our paper: ReLER@ ZJU-Alibaba Submission to the Ego4D Natural Language Queries Challenge 2022

Data preparation

Ego4d NLQ data

Pleasr follow the preparation section of Ego4d's VSLNet to preprocess the raw Ego4d NLQ data.

Pre-Extracted feature

We provide two Pre-Extracted feature for video and text by using CLIP (Vit-B/16).

Please download the Slowfast_vitb16CLIP_textfeature.zip and Slowfast_vitb16CLIP_videofeature.zip.
Upzip the Slowfast_vitb16CLIP_textfeature.zip and Slowfast_vitb16CLIP_videofeature.zip, place these folders in ./CLIP_feature_slowfast.

Quick Start

Train and Test

# To train the model.
bash ms_cm/scripts/train_ego4d_slowfast.sh \
     600 256 3 0.1 1 1 0.5 64 vlen600_slowfast

# To predict on eval set.
python -m ms_cm.inference_ego4d_slowfast \
      --resume ./results/video_tef-vlen600_slowfast/model_0146.ckpt --split val
      
# To predict on test set.
python -m ms_cm.inference_ego4d_slowfast \
      --resume ./results/video_tef-vlen600_slowfast/model_0146.ckpt --split test

Notably, the resume path "./results/video_tef-vlen600_slowfast/model_0146.ckpt "is just a example, you can change this path with the path of your own trained model checkpoint. We also prvoided the checkpoint: "model_0146.ckpt". If you want to use this chekpoint, just download and upzip it into ./results.
