| Unified place for determining if external dependencies are installed or not. | |
| You should import all external modules using the import_module() function. | |
| For example | |
| from sympy.external import import_module | |
| numpy = import_module('numpy') | |
| If the resulting library is not installed, or if the installed version | |
| is less than a given minimum version, the function will return None. | |
| Otherwise, it will return the library. See the docstring of | |
| import_module() for more information. | |
