Strict report as of 3/13/2025

[Dr-Irv]

When we do a merge, we run pyright using the strict option. Current statistics on the types of errors found:

reportUnknownMemberType       2387
reportUnknownParameterType    2112
reportMissingTypeArgument     1560 
reportMissingParameterType    1247
reportUnknownArgumentType      613
reportUnknownVariableType      428
reportUnusedVariable            88
reportUnknownLambdaType         58
reportUnusedExpression          41
reportPrivateUsage              15
reportMissingTypeStubs           7

Can be output by running poe test pyright_strict

There are 8556 errors, and 3541 of them are in the stubs themselves. Rest are reported from the tests (but may be due to the stubs).

FYI for @MarcoGorelli

Some simple things that would help:

• Change references to npt.NDArray to be npt.NDArray[Any, Any]
• Change args and kwargs (see question: how to type compatibility-only args / kwargs? #1168) in all stubs file
• Maybe change references from plain Series to UnknownSeries and change from plain Index to UnknownIndex in all stubs file
