# LAVILA Model Zoo

## Multi-node Training
We use multi-node training on a SLURM cluster with [submitit](https://github.com/facebookincubator/submitit) for producing the results and models in the paper.
Please install `submitit` in your conda environment:
```bash
pip install submitit
```


## Pre-training

Please refer to [PRETRAIN.md](./PRETRAIN.md).

^ Note that the pre-trained checkpoint to evaluate CharadesEgo is different from that to evalute other datasets.
Specifically, we use the checkpoint at epoch 1 to zero-shot evaluate CharadesEgo and the checkpoint that achieves best average mAP on EK-100 MIR to evaluate other datasets, as is done in [EgoVLP](https://arxiv.org/pdf/2206.01670.pdf).
Our guess is that since CharadesEgo videos (captured by head-mounted mobile cameras) are visually different from Ego4D/EPIC-Kitchens videos (captured by professional action cameras, eg GoPro), pre-training on Ego4D videos for longer will lead to some potential domain discrepancy.

^^ We use the checkpoints released by [EgoVLP](https://github.com/showlab/EgoVLP) and convert them to be compatible with this codebase. Also note that our reproduced numbers are better than the reported numbers, especially on EK-100 MIR since we evaluate on raw videos directly (for more details, check out Appendix F & Table 10 in our paper).

<details><summary>1. EK-100 MIR</summary>
<p>

```bash
python eval_zeroshot.py --dataset ek100_mir --root datasets/EK100/video_ht256px/ --clip-length 4 --resume $PATH
```
By increasing the number of frames per clip, eg `--clip-length 16`, you are expected to see a better performance.

<details><summary>Training and evaluating scripts</summary>
<p>

### Multi-node training (Slurm)
```bash
# TimeSformer-Base
python run_with_submitit_finetune_retrieval.py \
    --pretrain-model $PATH \
    --use-checkpoint --nodes 4

# TimeSformer-Large
python run_with_submitit_finetune_retrieval.py \
    --pretrain-model $PATH \
    --batch-size 4 \ 
    --use-checkpoint --nodes 4
```

### Single-machine training
```bash
torchrun --nproc_per_node=8 \
    main_finetune_retrieval.py \
    --output-dir $OUT_DIR \
    --pretrain-model $PATH \
    --use-checkpoint
```

Note that you might see a slight drop of performance when training on a single node compared to multiple nodes (everything else being the same) because of a smaller total batch size.

### Evaluation

Evaluation is done every `--eval-freq 5` epochs by default during fine-tuning.
If you want to evaluate any checkpoint after fine-tuning, please switch to `--evaluate` mode and specify the path to the checkpoint by `--resume $FINETUNED_CHECKPOINT`.
```bash
torchrun --nproc_per_node=1 \
    main_finetune_retrieval.py \
    --output-dir $OUT_DIR \
    --pretrain-model $PATH \
    --use-checkpoint \
    --evaluate \
    --resume $FINETUNED_CHECKPOINT
```
