Description
Bug Report
Dmypy ignores follow_imports=skip override on the second run.
To Reproduce
import IPython.terminal.prompts
reveal_type(IPython)
reveal_type(IPython.terminal.prompts)
pyproject.toml:
[tool.mypy]
python_version = "3.10"
follow_imports = "normal"
[[tool.mypy.overrides]]
module = [
"IPython.terminal.prompts",
]
follow_imports = "skip"
Expected Behavior
All runs of dmypy run bar.py will show the same output:
bar.py:4: note: Revealed type is "types.ModuleType"
bar.py:5: note: Revealed type is "Any"
Actual Behavior
The first run of dmypy run bar.py shows:
bar.py:4: note: Revealed type is "types.ModuleType"
bar.py:5: note: Revealed type is "Any"
The second run of dmypy run bar.py shows:
bar.py:4: note: Revealed type is "types.ModuleType"
bar.py:5: note: Revealed type is "types.ModuleType"
Running mypy bar.py works correctly every time.

Research direction
Start by reproducing the issue with dmypy run bar.py twice using the shown pyproject.toml and bar.py contents, then compare the daemon's output with repeated mypy bar.py runs. Done means every dmypy run respects the follow_imports = "skip" override and reports the expected revealed types.
