Docker容器：ImportError: libGL.so.1: 无法打开共享对象文件：没有此文件或目录
我有一个深度学习项目，使用的是flask框架。我想把它放到docker容器里，但当我启动容器时，网页上显示了这个错误：
内部服务器错误 服务器遇到了内部错误，无法完成你的请求。可能是服务器负载过重，或者应用程序出现了错误。
这是容器的日志：

我有一个requirements.txt文件，里面列出了所有需要的包。
我尝试重新安装所有的包，但还是不行。
这是dockerfile：
# Use an official Python runtime as a parent image
FROM python:3.12.2
# Set the working directory in the container to /app
WORKDIR /app
# Install any needed packages specified in requirements.txt
COPY requirements.txt .
RUN pip install -r requirements.txt
# Copy the current directory contents into the container at /app
COPY . .
# Make port 5000 available to the world outside this container
EXPOSE 5000
# Run the command to start your application
CMD cd process && flask run --host=0.0.0.0

解决办法是我在 requirements.txt 文件中添加了这个包：
opencv_python_headless
但是现在我遇到了一个相机错误：
[ WARN:0@0.008] global cap_v4l.cpp:997 open VIDEOIO(V4L2:/dev/video0): can't open camera by index
[ERROR:0@0.008] global obsensor_uvc_stream_channel.cpp:159 getStreamChannelGroup Camera index out of range
