lazy-import模塊

簡而言之只在使用時候纔會用到模塊。

pip install lazy-import

lazy_import provides a set of functions that load modules, and related attributes, in a lazy fashion. This allows deferring of ImportErrors to actual module use-time. Likewise, actual module initialization only takes place at use-time. This is useful when using optional dependencies with heavy loading times and/or footprints, since that cost is only paid if the module is actually used.
