PyCharm suggests a number of solutions. For example, choose one of the following options:
Import this name to add an import statement.
- Create parameter to add a parameter with some initial value to the list of function parameters.
Ignore unresolved reference <fully qualified symbol name>. So doing, the fully qualified name of the symbol in question will be added to the list of ignored references (File | Settings/Preferences | Editor | Inspections - Python - Unresolved references).
Mark all attributes of <fully qualified type name> as ignored. In this case, the list of ignored references (File | Settings/Preferencdes | Editor | Inspections - Python - Unresolved references) will be modified with the fully qualified name of the type in question with the wildcard (*) at the end.
