简介

本篇介绍一个使用 YOLOv8 目标检测算法和 DeepSort 目标跟踪算法的开源项目。

实操

git clone https://github.com/MuhammadMoinFaisal/YOLOv8-DeepSORT-Object-Tracking.git
cd YOLOv8-DeepSORT-Object-Tracking

# 创建一个全新的虚拟环境
conda create -n py38 python=3.8

# 激活虚拟环境
conda activate py38

# 安装依赖
pip install -e .

https://drive.google.com/drive/folders/1kna8eWGrSfzaR6DtNJ8_GchGgPMv3VC8,将整个文件夹下载,下来的是一个 zip ,将 zip 解压后, 文件夹放在目录 ultralytics/yolo/v8/detect

YOLOv8 DeepSort

准备一段视频检测素材,放到目录 ultralytics/yolo/v8/detect 下,然后执行命令

# 使用yolov8l.pt模型,首次执行,会自动取下载,测试视频是10s.mp4,show参数表示处理过程中显示处理结果图像
python predict.py model=yolov8l.pt source="10s.mp4" show=True

    self.tlwh = np.asarray(tlwh, dtype=np.float)
  File "D:\Tools\anaconda3\envs\py38\lib\site-packages\numpy\__init__.py", line 305, in __getattr__
    raise AttributeError(__former_attrs__[attr])
AttributeError: module 'numpy' has no attribute 'float'.
`np.float` was a deprecated alias for the builtin `float`. To avoid this error in existing code, use `float` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.float64` here.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
    https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations

Set the environment variable HYDRA_FULL_ERROR=1 for a complete stack trace.

这是由于 numpy 新版已经没有 float 属性了,降版本解决 pip install numpy==1.23.5

NotImplementedError: Could not run 'torchvision::nms' with arguments from the 'CUDA' backend. This could be because the operator doesn't exist for this backend, or was omitted during the selective/custom build process (if using custom build). If you are a Facebook employee using PyTorch on mobile, please visit https://fburl.com/ptmfixes for possible resolutions. 'torchvision::nms' is only available for these backends: [CPU, Meta, QuantizedCPU, BackendSelect, Python, FuncTorchDynamicLayerBackMode, Functionalize, Named, Conjugate, Negative, ZeroTensor, ADInplaceOrView, AutogradOther, AutogradCPU, AutogradCUDA, AutogradXLA, AutogradMPS, AutogradXPU, AutogradHPU, AutogradLazy, AutogradMeta, Tracer, AutocastCPU, AutocastCUDA, FuncTorchBatched, BatchedNestedTensor, FuncTorchVmapMode, Batched, VmapMode, FuncTorchGradWrapper, PythonTLSSnapshot, FuncTorchDynamicLayerFrontMode, PreDispatch, PythonDispatcher].

这个错误一般是由于 torchtorchvision 版本不匹配引起的,可以先卸载再重新安装。

pip uninstall torch torchvison

# 以安装gpu版本为例
pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu118
