Updating dependencies
Resolving dependencies...


The current project's supported Python range (>=3.7,<4.0) is not compatible with some of the required packages Python requirement:
  - graphviz requires Python >=3.9, so it will not be satisfied for Python >=3.7,<3.9

Because no versions of graphviz match >0.21,<0.22.0
 and graphviz (0.21) requires Python >=3.9, graphviz is forbidden.
So, because diagrams-ext depends on graphviz (>=0.21,<0.22.0), version solving failed.

  • Check your dependencies Python requirement: The Python requirement can be specified via the `python` or `markers` properties
    
    For graphviz, a possible solution would be to set the `python` property to ">=3.9,<4.0"
