[Python] importlib direct import absolute path

Sometimes common scripts like to write api, In this way, you don't need to build wheels repeatedly when you use them . Put away the good ones. api Put it in a fixed position , Just quote directly every time .

The modules used here are importlib.

Suppose we write a wheel , Name it a.py：

class Dancer:
def __init__(self):
self.name = 'cxk'
def dance(self):
print(')()()()(')

We import This api You can refer to the following script ：

import importlib
filepath = '/home/ubuntu/my_libs/a.py'
spec = importlib.util.spec_from_file_location('dancer', file_path)
the_api = importlib.util.module_from_spec(spec)
spec.loader.exec_module(the_api)
dancer = mini_api.Inferencer()
dancer.dance()
