Module lazily
Lazily import pygeodesy3 modules and attributes, based on
lazy_import from Brett Cannon's modutil.
Lazy import is supported only for Python 3.7+ and enabled always in PyGeodesy3.
To enable lazy import, set env
variable PYGEODESY3_LAZY_IMPORT to1,
2, 3 prior to import pygeodesy3.
Use 2 or higher to print a message for each lazily imported
module and attribute, similar to env variable
PYTHONVERBOSE showing imports. Using 3 or
higher also shows the importing file name and line number.
Notes:
-
Lazy import applies only to top-level modules of
pygeodesy3. A lazy import of a top-level
module invariably loads all sub-modules imported by that top-level
module.
-
Lazy import raises a LazyAttributeError or LazyImportError depending on the cause of the
error. Such errors can occur late, after all initial imports.
