  × No solution found when resolving dependencies:
  ╰─▶ Because the requested Python version (>=3.10) does not satisfy Python>=3.11 and perception-models==1.0.0 depends
      on Python>=3.11, we can conclude that perception-models==1.0.0 cannot be used.
      And because only perception-models==1.0.0 is available and your project depends on perception-models, we can
      conclude that your project's requirements are unsatisfiable.

      hint: The `requires-python` value (>=3.10) includes Python versions that are not supported by your dependencies
      (e.g., perception-models==1.0.0 only supports >=3.11). Consider using a more restrictive `requires-python` value
      (like >=3.11).

Can you also update the README to reflect the change. It currently says python 3.10 under requirements section
