Could not build wheels for onnxoptimizer, which is required to install pyproject.toml-based projects

I'm sorry to hear that you're having trouble building wheels for onnxoptimizer. This error usually occurs when there are missing dependencies or conflicts with the project's requirements. Here are a few steps you can try to resolve this issue:

1. Make sure you have the latest version of pip and setuptools installed:

   pip install --upgrade pip setuptools

2. Install the required system dependencies for building Python packages. This may vary depending on your operating system. For example, on Ubuntu, you can run:

   sudo apt-get install build-essential

3. Install the necessary libraries and development headers for the dependencies of onnxoptimizer. These can include numpy, Cython, and other required packages. You can typically install them using pip:

   pip install numpy Cython

4. Try installing onnxoptimizer again:

   pip install onnxoptimizer

If the issue persists, it's possible that there may be compatibility problems between onnxoptimizer and other packages in your environment. In such cases, you might consider creating a clean virtual environment and installing only the required dependencies.
