By default, if a dependency is missing an ImportError with a nice message will be raised. If a dependency is present, but too old, we raise. Parameters ---------- name : str The module name. extra : str Additional text to include in the ImportError message. errors : str {'raise', 'warn', 'ignore'} What to do when a dependency is not found or its version is too old. * raise : Raise an ImportError * warn : Only applicable when a module's version is to old. Warns that the version is too old and returns None * ignore: If the module is not installed, return None, otherwise, return the module, even if the version is too old. It's expected that users validate the version locally when using ``errors="ignore"`` (see. ``io/html.py``) min_version : str, default None Specify a minimum version that is different from the global pandas minimum version required. Returns ------- maybe_module : Optional[ModuleType] The imported module, when found and the version is correct. None is returned when the package is not found and `errors` is False, or when the package's version is too old and `errors` is ``'warn'``. >ignorewarnrNzMissing optional dependency 'z'. z Use pip or conda to install .rrzPandas requires version 'z' or newer of 'z ' (version 'z' currently installed).r)AssertionErrorINSTALL_MAPPINGget importlib import_modulersplitsysmodulesVERSIONSrrwarningsr UserWarning) rrrr package_nameZ install_namemsgr parentZ module_to_getminimum_versionrrrrimport_optional_dependency@s8)        r.)rrN) __future__rr"r%typesr(Zpandas.util.versionrr'r rr.rrrrsV
