  × No solution found when resolving dependencies for split (markers: python_full_version >= '3.10'; included: datamodel-code-generator[group:pydantic1]; excluded:
  │ datamodel-code-generator[group:black22], datamodel-code-generator[group:black23], datamodel-code-generator[group:black24], datamodel-code-generator[group:dev]):
  ╰─▶ Because datamodel-code-generator:pkg-meta depends on check-wheel-contents>=0.6.1 and only the following versions of check-wheel-contents are available:
          check-wheel-contents<=0.6.1
          check-wheel-contents==0.6.2
          check-wheel-contents==0.6.3
      we can conclude that datamodel-code-generator:pkg-meta depends on check-wheel-contents>=0.6.1.
      And because check-wheel-contents>=0.6.1 depends on pydantic>=2.0 and datamodel-code-generator:pydantic1 depends on pydantic<2, we can conclude that datamodel-code-generator:pydantic1 and
      datamodel-code-generator:pkg-meta are incompatible.
      And because your project requires datamodel-code-generator:pkg-meta and datamodel-code-generator:pydantic1, we can conclude that your project's requirements are unsatisfiable.
