在 Docker 中使用网络摄像头运行 yolov5

Question

我正在尝试从 Docker 容器中的 Nvidia Jetson Nano 对网络摄像头流上的 yolov5 模型进行推理。在我的 Windows PC 和 Jetson 上，我都收到错误：

qt.qpa.xcb: could not connect to display 
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/usr/local/lib/python3.10/site-packages/cv2/qt/plugins" 
even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: xcb.

Aborted

Dockerfile 看起来像这样：

FROM python:latest

WORKDIR /yolov5_aiss

COPY requirements.txt . 

RUN pip3 install -r requirements.txt

COPY ./app ./app
RUN apt-get update -y
RUN apt-get install -y ffmpeg libsm6 libxext6  -y
RUN apt install -y libxkbcommon-x11-0

CMD ["python", "./app/detect.py", "--weights","./app/weights/best.pt", "--source", "0"]

Answer 1

这是解决方法。

pip uninstall opencv-python
pip install opencv-python-headless

但是，我想你会得到另一个与 opencv 相关的错误。
