# Satvision Pretraining Dataset - Small

- **Developed by:** NASA GSFC CISTO Data Science Group
- **Model type:** Pre-trained visual transformer model
- **License:** Apache license 2.0

This dataset repository houses the pretraining data for the Satvision pretrained transformers.
This dataset was constructed using [webdatasets](https://github.com/webdataset/webdataset) to
limit the number of inodes used in HPC systems with limited shared storage. Each file has 100000
tiles, with pairs of image input and annotation. The data has been further compressed to ease
the download from HuggingFace.

SatelliteVision-Base (SatVis-B) is a pre-trained vision transformer based on the SwinV2 mode architecture.
The model is pre-trained on global MODIS surface reflectance data from which 1.99 million image chips were used. SatVis-B is pre-trained using
the masked-image-modeling (MIM) contrastive pre-training strategy. The MIM pre-training approach utilizes random
masking of the input geospatial image chip, using a linear layer to regress the raw pixel values of the masked
area with an l1 loss serving as the loss function.

Resolution of the pre-training MODIS chips was `128x128` with a window size of `16x16`. SatViz-B was pre-trained
for `800` epochs on 8x A100 GPUs and 12x V100 GPUs.

## Getting Started with SatVision-Base

- **Training repository:** https://github.com/nasa-nccs-hpda/pytorch-caney
- **Pre-training dataset repository:** https://huggingface.co/datasets/nasa-cisto-data-science-group/satvision-pretrain-small

### Installation

If you have singularity installed
```bash
$ git clone git@github.com:nasa-nccs-hpda/pytorch-caney.git
$ singularity build --sandbox pytorch-caney.sif docker://nasanccs/pytorch-caney:latest
# To shell into the container
$ singularity shell --nv -B <mounts> pytorch-caney.sif
```

Anaconda installation
```bash
$ git clone git@github.com:nasa-nccs-hpda/pytorch-caney.git
$ conda create -n satvision-env python==3.9
```

### Fine-tuning Satvision-Base
- Create config file [example config](https://github.com/nasa-nccs-hpda/pytorch-caney/blob/finetuning/examples/satvision/finetune_satvision_base_landcover5class_192_window12_100ep.yaml)
- Download checkpoint from this HF model repo
- `$ git clone git@github.com:nasa-nccs-hpda/pytorch-caney.git`
- Add a new pytorch dataset in pytorch-caney/pytorch_caney/data/datasets/
- Add new pytorch dataset to dict in pytorch-caney/pytorch_caney/data/datamodules/finetune_datamodule.py
```bash
torchrun --nproc_per_node <NGPUS> pytorch-caney/pytorch_caney/pipelines/finetuning/finetune.py --cfg <config-file> --pretrained <path-to-pretrained> --dataset <dataset-name (key for new dataset)> --data-paths <path-to-data-dir> --batch-size <batch-size> --output <output-dir> --enable-amp
```

### Pre-training with pytorch-caney

## Pre-training with SatVision-Base with Masked Image Modeling and pytorch-caney

To pre-train the swinv2 base model with masked image modeling pre-training, run:
```bash
torchrun --nproc_per_node <NGPUS> pytorch-caney/pytorch_caney/pipelines/pretraining/mim.py --cfg <config-file> --dataset <dataset-name> --data-paths <path-to-data-subfolder-1> --batch-size <batch-size> --output <output-dir> --enable-amp
```

For example to run on a compute node with 4 GPUs and a batch size of 128 on the MODIS SatVision pre-training dataset with a base swinv2 model, run:

```bash
singularity shell --nv -B <mounts> /path/to/container/pytorch-caney-container
Singularity> export PYTHONPATH=$PWD:$PWD/pytorch-caney
Singularity> torchrun --nproc_per_node 4 pytorch-caney/pytorch_caney/pipelines/pretraining/mim.py --cfg pytorch-caney/examples/satvision/mim_pretrain_swinv2_satvision_base_192_window12_800ep.yaml --dataset MODIS --data-paths /explore/nobackup/projects/ilab/data/satvision/pretraining/training_* --batch-size 128 --output . --enable-amp
```
