Correct Macos M1 configuration yolov5 environment

For my novice, I encountered a lot of problems installing yolov5, so I decided to record him, hoping that future generations can avoid pitfalls.

The first step is to install anaconda

Anaconda | Anaconda Distribution  Install the m1 graphical installer in this website.

After the installation is complete, a software icon will not appear like other non-m1 systems.

The second step is to install yolov5

https://github.com/ultralytics/yolov5/tree/v5.0  refer to other tutorials

The third step is to install pycharm

The fourth step is to open the preference in pycharm

The fifth step is to click add interpreter, then select add local interpreter, and then select conda environment,

Change python to 3.9 and click ok, then apply

 Then enter it in the terminal of pycharm

pip install -r requirements.txt

pip install opencv-python
pip install opencv-contrib-python

conda uninstall pytorch torchvision torchaudio


pip install torch==1.10.1 torchvision==0.11.2 torchaudio==0.10.1

At this point, clicking Run should generate two pictures under run/detect/exp.

I have been unsuccessful before and jumped out of many mistakes. Finally, I read an article and found that the version of pytorch is too high.
