Warning: The lock file is not up to date with the latest changes in pyproject.toml. You may be getting outdated dependencies. Run update to update them.
[SolverProblemError]
Because annotator depends on Cython (0.29.15) which doesn't match any versions, version solving failed.
Cython was specified by 0.29.15.
pyproject.toml
...
[tool.poetry.dependencies]
Cython = "0.29.15"
...
You can do it with poetry add.
(.venv) user$ poetry add Cython
Using version ^0.29.15 for Cython

With poetry add, the version is automatically specified with^.
pyproject.toml
...
[tool.poetry.dependencies]
Cython = "^0.29.15"
...
Apparently this was necessary.
Cython = 0.29.15 is also on the pypi and documents
According to this method, > = 0.29.15 <1.0.0 should be specified, so it seems that it is okay to specify 0.29.15. .. ..
By the way, you can specify Cython =" ^ 0.29.15 " and ʻinstall instead of ʻadd.
