毕业设计&课程设计-Simple Demo of yolov5 (FastAPI, Celery, Redis).zip

# 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 <a href="https://apps.apple.com/app/id1452689527" target="_blank"> <img src="https://user-images.githubusercontent.com/26833433/82944393-f7644d80-9f4f-11ea-8b87-1a5b04f555f1.jpg" width="1000"></a> &nbsp  This repository represents Ultralytics open-source research into future object detection methods, and incorporates our lessons learned and best practices evolved over training thousands of models on custom client datasets with our previous YOLO repository https://github.com/ultralytics/yolov3. **All code and models are under active development, and are subject to modification or deletion without notice.** Use at your own risk. <img src="https://user-images.githubusercontent.com/26833433/90187293-6773ba00-dd6e-11ea-8f90-cd94afc0427f.png" width="1000">** GPU Speed measures end-to-end time per image averaged over 5000 COCO val2017 images using a V100 GPU with batch size 32, and includes image preprocessing, PyTorch FP16 inference, postprocessing and NMS.
