If you are facing an issue where wheels for pycairo couldn't be built, which is necessary for installing pyproject.toml-based projects and then you can try the below step to solve this issue.

  1.  Outdated versions of pip and setuptools can give issues. We can upgrade them using the following commands:
    2. python -m pip install --upgrade pip setuptools
  2. pycairo can require system-level dependencies to be installed in the machine, you need to make sure that all required libraries are present on our system. On Linux, we can use the package manager (e.g., apt or yum) to install necessary dependencies. On MacOS, we can use Homebrew. For example, on Ubuntu, we can run:
    3. sudo apt-get install libcairo2-dev
  3. Before installing Keras or any other pyproject.toml-based project, you can try installing pycairo separately to check if there are any errors:
    4. pip install pycairo
