# About this README

I tested these instructions on MacOS, but should work on linux as well.

## Segment Anything models

It's possible to prepare the model files using <https://github.com/vietanhdev/samexporter/> or using the ones
from <https://huggingface.co/aletrn/sam-quantized> (copy them within the folder `/machine_learning_models`).

In this case after the clone of this repository it's best to initialize the `sam-quantized` submodule:

```bash
git submodule update --init --recursive
```

## SamGIS - Gradio SDK version

After developed your project using [the gradio quickstart](https://www.gradio.app/guides/quickstart),
you can declare the specific gradio version you want to use in the HuggingFace space using
the README.md header section. You need to compile these fields:

```
sdk: gradio
sdk_version: [current Gradio version, e.g. 4.44.0]
app_file: app.py
```

For some reason the space won't work if the app_file setting points to a file not
within the root folder project.

Under the hood, HuggingFace install the gradio SDK using docker. If you need to install some dependencies
(for this project I needed `nodejs`) you can add some system
[debian packages](https://huggingface.co/docs/hub/spaces-dependencies#adding-your-own-dependencies)
within the `pre-requirements.txt` file.

If you want to run locally the project not from a docker container you can install the optional gradio poetry group like this:

```bash
poetry install --with gradio --with --no-root
```


## SamGIS - Docker version

The SamGIS HuggingSpace url is <https://huggingface.co/spaces/aletrn/samgis>.
Build the docker image this way:

```bash
# clean any old active containers
docker stop $(docker ps -a -q); docker rm $(docker ps -a -q)

# build the base docker image from the repository root folder using ARGs:
# - DEPENDENCY_GROUP=fastapi used by poetry
# VITE__MAP_DESCRIPTION, VITE__SAMGIS_SPACE used by 'docker build'
(
  set -o allexport && source <(cat ./static/.env|grep VITE__) && set +o allexport;
  env|grep VITE__;
  docker build . -f dockerfiles/dockerfile-samgis-base --progress=plain \
  --build-arg VITE__MAP_DESCRIPTION="${VITE__MAP_DESCRIPTION}" \
  --build-arg VITE__SAMGIS_SPACE="${VITE__SAMGIS_SPACE}" \
  --build-arg VITE__STATIC_INDEX_URL="${VITE__STATIC_INDEX_URL}" \
  --tag registry.gitlab.com/aletrn/gis-prediction
)

# build the image, use the tag "samgis-huggingface"
docker build . --tag registry.gitlab.com/aletrn/samgis-huggingface --progress=plain
```

Run the container (keep it on background) and show logs

```bash
docker run  -d --name samgis-huggingface -p 7860:7860 \
  -e VITE__STATIC_INDEX_URL=${VITE__STATIC_INDEX_URL} \
  -e VITE__INDEX_URL=${VITE__INDEX_URL} \
  -e MOUNT_GRADIO_APP="" \
  registry.gitlab.com/aletrn/samgis-huggingface; docker logs -f samgis-huggingface
```

Test it with curl using a json payload:

```bash
URL=http://localhost:7860/infer_samgis
curl -d@./events/payload_point_eolie.json -H 'content-type: application/json' ${URL}
```

or better visiting the swagger page on <http://localhost:7860/docs>

### Dependencies installation, local execution and local tests

The docker build process needs only the base dependency group plus the `aws_lambda` or `fastapi` optional one (right now I use almost only the `fastapi` version). Install also the `test` and/or `docs` groups if needed.

#### Local execution

If you need to use the SPA frontend follow the frontend instruction [here](/static/README.md).

You can run the local server using this python command:

```python
uvicorn app:app --host 127.0.0.1 --port 7860
```

Change the port and/or the host ip if needed. Test it with curl using a json payload:

```bash
URL=http://localhost:7860/infer_samgis
curl -d@./events/payload_point_eolie.json -H 'content-type: application/json' ${URL}
```

#### Local execution on MacOS

There is a known issue running the project on MacOS. SamGIS still work also without executing it within a docker container, but is slower during image embedding because of a memory leak caused by CoreML. Here a log about this bug:

```less

```

This problem doesn't rise if running it within the docker container.

### Tests

Tests are defined in the `tests` folder in this project. Use PIP to install the test dependencies and run tests.

```bash
python -m pytest --cov=samgis --cov-report=term-missing && coverage html
```

### How to update the static documentation with sphinx

This project documentation uses sphinx-apidoc: it's a tool for automatic generation of Sphinx sources that, using the autodoc
extension, document a whole package in the style of other automatic API documentation tools. See the
[documentation page](https://www.sphinx-doc.org/en/master/man/sphinx-apidoc.html) for details.
Run the command from the project root:

```bash
# missing docs folder (run from project root) initialize this way
# 
cd docs && sphinx-quickstart --project SamGIS --release 1.0.0 --language python --master index

# update docs folder (from project root) referring to the other packages folder
sphinx-apidoc -f -o docs /path/to/samgis_web
sphinx-apidoc -f -o docs /path/to/samgis_core
```

Then it's possible to generate the HTML pages

```bash
cd docs && make html && ../

# to clean old files
cd docs && make clean html && cd ../
```

The static documentation it's now ready at the path `docs/_build/html/index.html`.

To create a work in progress openapi json or yaml file use

- `extract-openapi-fastapi.py`
- `extract-openapi-lambda.py` (useful to export the json schema request and response from lambda app api)
