# ABOUT

This is a clone from yolov5 with a simple API to query for detections. It's a simple demo to test model deployment as a microservice. The default detect method has been slightly modified to use a config dict instead of the given script arguments to facilitate the integration with the API

# First Steps

Once you have your machine up and running, createa  new sudo user to avoid using root, it is not secure and might casue issues with some packages
`sudo useradd -s /path/to/shell -d /home/{dirname} -m -G {secondary-group} {username}`

## 1. Create Sudo User

Before following the instructions below, create a new virtual environment with virtualenv or [pyenv](https://github.com/pyenv/pyenv-installer)

## 2. Install Pyenv (virtual environment manager)

1. Install Pyenv Dependancies

`sudo apt update ; sudo apt install -y make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev xz-utils tk-dev libffi-dev liblzma-dev python-openssl git`

2. Install pyenv

`curl -L https://github.com/pyenv/pyenv-installer/raw/master/bin/pyenv-installer | bash`

3. add the lines below to your .bashrc

```
export PATH="/home/ubuntu/.pyenv/bin:$PATH"
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"
```

1. Run the following command to make sure pyenv is callable:

`source ~/.bashrc`

## 3. Create New virtualenv

2. Install python 3.8>

`pyenv install 3.8.3`

3. Create a new virtualenv with the installed version

`pyenv virtualenv 3.8.3 demoyolo`

4. Activate your virtualenv

`pyenv activate demoyolo`

5. Set the environment variables for the project

This projects uses a couple of environment variables, to set them copy the .env.example file to .env in the projects root directory, and change the environment variables needed (by default environment variables are already set to facilitate the demo)

`cp .env.example .env`

# Optional Steps

# Low RAM? , add a swapfile!

If your server has 3G<= of RAM `opencv`, and `torch` might fail to build. Instructions on how to add swap can be found here [here](https://linuxize.com/post/how-to-add-swap-space-on-ubuntu-20-04/)

# Yolov5's original readme.
1. Read the steps below to get the model working and be able to test the api..

2. Once the model is up and running, follow the steps ad api/README.md

** APtest denotes COCO [test-dev2017](http://cocodataset.org/#upload) server results, all other AP results in the table denote val2017 accuracy. 
** All AP numbers are for single-model single-scale without ensemble or test-time augmentation. **Reproduce** by `python test.py --data coco.yaml --img 640 --conf 0.001` 
** SpeedGPU measures end-to-end time per image averaged over 5000 COCO val2017 images using a GCP [n1-standard-16](https://cloud.google.com/compute/docs/machine-types#n1_standard_machine_types) instance with one V100 GPU, and includes image preprocessing, PyTorch FP16 image inference at --batch-size 32 --img-size 640, postprocessing and NMS. Average NMS time included in this chart is 1-2ms/img. **Reproduce** by `python test.py --data coco.yaml --img 640 --conf 0.1` 
** All checkpoints are trained to 300 epochs with default settings and hyperparameters (no autoaugmentation). 
** Test Time Augmentation ([TTA](https://github.com/ultralytics/yolov5/issues/303)) runs at 3 image sizes. **Reproduce** by `python test.py --data coco.yaml --img 832 --augment`

## Inference

Inference can be run on most common media formats. Model [checkpoints](https://drive.google.com/open?id=1Drs_Aiu7xx6S-ix95f9kNsA6ueKRpN2J) are downloaded automatically if available. Results are saved to `./inference/output`.
```bash
$ python detect.py --source 0  # webcam
                            file.jpg  # image 
                            file.mp4  # video
                            path/  # directory
                            path/*.jpg  # glob
                            rtsp://170.93.143.139/rtplive/470011e600ef003a004ee33696235daa  # rtsp stream

## Training

Download [COCO](https://github.com/ultralytics/yolov5/blob/master/data/scripts/get_coco.sh) and run command below. Training times for YOLOv5s/m/l/x are 2/4/6/8 days on a single V100 (multi-GPU times faster). Use the largest `--batch-size` your GPU allows (batch sizes shown for 16 GB devices).
```bash
$ python train.py --data coco.yaml --cfg yolov5s.yaml --weights '' --batch-size 64
 yolov5m 40
 yolov5l 24
