`--untyped-calls-exclude` does not exclude some packages/libraries

Bug Report
I have not been able to find any issues discussing a similar situation, so I'm filing this bug. I apologize in advanced if this is just a configuration issue. As best as I can currently tell, this appears to be a bug.

I have an experimental branch on conda-recipe-manager that uses conda's MatchSpec module and the networkx library. I can use --untyped-calls-exclude to prevent type checking on any use of the MatchSpec class, but I cannot do the same for anything in the networkx library. I have tried just excluding networkx in our mypy.ini file and that does not resolve my issue.

This is speculation at this point, but conda is packaged with a py.typed file, even though not every module has type annotations. networkx does not announce or include any typing. I think that might be causing a rule to fire before the exclusion rule takes effect. I say this because everything I've tried causes the following error messages to be emitted, and I do not get these errors when I exclude MatchSpec:

error: Skipping analyzing "networkx": module is installed, but missing library stubs or
py.typed marker  [import-untyped]
    import networkx as nx
    ^
error: Skipping analyzing "networkx.drawing.nx_agraph": module is installed, but
missing library stubs or py.typed marker  [import-untyped]
    from networkx.drawing.nx_agraph import graphviz_layout

I have run into this issue on mypy versions 1.10 and 1.11.

Things I have tried but have not gotten to work:

• Only excluding networkx (either by .mypy.ini or through the command line
• Setting disallow_any_unimported to False
• Using import networkx without aliasing to nx
• Specifically excluding networkx.drawing.nx_agraph in addition and without excluding networkx directly

If I do not exclude MatchSpec, I receive this error upon invoking the constructor:

error: Call to untyped function "MatchSpec" in typed context  [no-untyped-call]

And then a error: Expression has type "Any" [misc] on any line referencing the instantiated MatchSpec object.

To Reproduce

import networkx as nx
foo0 = nx.DiGraph()  # error: Expression has type "Any"  [misc]

from conda.models.MatchSpec:
foo1 = MatchSpec("")  # Works fine when excluded. If not excluded, generates: error: Call to untyped function "MatchSpec" in typed context  [no-untyped-call]
print(foo1.name)  # Works fine when excluded. If not exclude, generates: error: Expression has type "Any"  [misc]

Here is our .mypy.ini

Expected Behavior

I would expect that any module used from networkx would skip type-evaluation. In other words, I would expect using --untyped-calls-exclude to ignore all usage from networkx. This appears to be what happens when MatchSpec is used with the --untyped-calls-excluded option.

Actual Behavior

mypy produces many errors when networkx is used in our project because it does not ship with any type annotations.

Your Environment

• Mypy version used: 1.10.0 and 1.11.1
• Mypy command-line flags: mypy --config-file=.mypy.ini --cache-dir=/dev/null conda_recipe_manager/ tests/ scripts/
• Mypy configuration options from mypy.ini (and other config files): (See above .mypy.ini)
• Python version used: 3.12.4

Riproduci il report con il file .mypy.ini fornito, gli import di networkx e conda.models.MatchSpec e il comando mypy indicato. Inizia tracciando l’implementazione e la logica di corrispondenza di --untyped-calls-exclude; il lavoro è completo quando l’import di networkx e le chiamate non producono più gli errori segnalati untyped-import, no-untyped-call e Any, mentre il comportamento esistente di MatchSpec rimane intatto.
