ERROR: Failed building wheel for opencv-contrib-python Running setup.py clean for opencv-contrib-python Failed to build opencv-contrib-python ERROR: Could not build wheels for opencv-contrib-python which use PEP 517 and cannot be installed directly WARNING: You are using pip version 19.2.3, however version 23.1.2 is available. You should consider upgrading via the 'python -m pip install --upgrade pip' command.

这个错误提示显示无法为 opencv-contrib-python 构建 wheel，可能是由于缺少构建依赖项导致的。建议你尝试安装所需的依赖项，然后再次尝试安装 opencv-contrib-python。你可以使用以下命令安装依赖项：

pip install numpy setuptools cmake

安装完成后，再次尝试安装 opencv-contrib-python：

pip install opencv-contrib-python

如果仍然无法解决问题，可以尝试使用 conda 安装 opencv-contrib-python，或者在相关社区寻求帮助。另外，警告提示建议你升级 pip 版本，你可以使用以下命令升级：

python -m pip install --upgrade pip

Running setup.py bdist_wheel for opencv-contrib-python ...

It seems like you are trying to build a wheel distribution for the `opencv-contrib-python` package using setup.py. Building a wheel distribution allows you to easily distribute and install Python packages.

To build the wheel distribution for `opencv-contrib-python`, you can follow these steps:

1. Make sure you have the necessary dependencies installed. You may need to install `numpy` and other required packages beforehand.

2. Navigate to the directory where the `setup.py` file for `opencv-contrib-python` is located.

3. Open a command prompt or terminal in that directory.

4. Run the following command to build the wheel distribution:

   python setup.py bdist_wheel

This command will execute the `setup.py` script and generate a wheel distribution file (with a .whl extension) in the `dist` directory.

5. Once the wheel distribution is generated, you can install it using pip by running:

   pip install path/to/wheel/file.whl

Replace `path/to/wheel/file.whl` with the actual path to the generated wheel distribution file.

Note that these instructions assume you have Python and pip properly installed on your system. Make sure you have the correct versions of Python and other dependencies required by `opencv-contrib-python`.

Building wheels for collected packages: opencv-contrib-python Building wheel for opencv-contrib-python (PEP 517) ... \

这是一条关于正在构建`opencv-contrib-python`包的信息。`PEP 517`是Python Enhancement Proposal（Python增强提案）之一，它定义了一种新的构建Python软件包的标准方式。这条信息表明正在使用PEP 517标准来构建`opencv-contrib-python`包的轮子。这是一条非常技术性的信息，可能对大多数用户没有太大的用处。你还有其他问题需要我回答吗？
