Today I run my python(.py) file as usual,but the terminal shows a new problem which I cannot solve for a long time. Explicitly,I used to click Run Python File,

I then tried another two ways to run my python,such as "run code"(code runner provides),debug(python plugin together with "run python file"),and it shows that:

It is obvious that except the "debug",other two both fail to run,showing "ModuleNot..."(while actually the module exists in the vir env). All codes are easy:
print('Hello World')
import os
print(os.path.abspath(__file__))
import numpy as np
