Setup YoloV5 on a raspberry pi 4

Get your os image from this site: https://www.raspberrypi.org/software/raspberry-pi-desktop/ and flash it to a tf card; when you booted up successful，you can follow with steps below；

Notice: With the 64-bit OS version, although our environment is configured correctly, we got the error 'illegal instruction' without running;

update the system,and install some base package;

1. sudo apt-get update
2. sudo apt-get dist-upgrade
3. sudo apt-get install libopenblas-dev libblas-dev m4 cmake cython python3-dev python3-yaml python3-setuptools

install virtualenv for system python3;

1. sudo pip3 install virtualenv

get the yolov5 clone;

1. git clone https://github.com/ultralytics/yolov5
2. cd yolov5

create a virtual environment of python3 and active it；

1. virtualenv yolov5-venv
2. source ./yolov5-venv/bin/activate

update pip3 of the environment;

1. python3 -m pip install --upgrade pip

By the way, pytorch has not provided an official compiled packages of arm32 (arm64 only); you need to download both packages in release here;

wget https://github.com/weirros/yolov5_wi_pi4/releases/download/Torch1.7/torch-1.7.0a0-cp37-cp37m-linux_armv7l.whl

wget https://github.com/weirros/yolov5_wi_pi4/releases/download/Torch1.7/torchvision-0.8.0a0+45f960c-cp37-cp37m-linux_armv7l.whl

install some package for the environment; Do not use pip3 install -r requirements.txt,it leads errors;

1. pip3 install numpy
2. python3.7 -m pip install torch-1.7.0a0-cp37-cp37m-linux_armv7l.whl
3. python3.7 -m pip install torchvision-0.8.0a0+45f960c-cp37-cp37m-linux_armv7l.whl
4. python3.7 -m pip install matplotlib
5. python3.7 -m pip install opencv-python
6. python3.7 -m pip install pyyaml
7. python3.7 -m pip install pandas
8. python3.7 -m pip install h5py
9. python3.7 -m pip install scipy
10. python3.7 -m pip install keras
11. python3.7 -m pip install tensorboard
12. python3.7 -m pip install tqdm
13. python3.7 -m pip install seaborn

now you can try;

1. python3.7 detect.py usually you can see the running out；

**but if you get some error ,like **

*getting ImportError: libopenblas.so.0: cannot open shared object file or directory

you may need install this lib of system;

1. sudo apt-get install libjpeg8-dev -y
2. sudo apt-get install libatlas-base-dev gfortran -y
3. sudo apt-get install libgtk2.0-dev -y
4. sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev -y
5. sudo apt-get install libtiff5-dev -y
6. sudo apt-get install libjasper-dev -y
7. sudo apt-get install libpng12-dev -y
8. sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev -y
9. sudo apt install libopenblas-dev libblas-dev m4 cmake cython python3-dev python3-yaml python3-setuptools
