No, they're scripts and on Linux you get 4 flavors, activate  
activate.csh  activate.fish, and Activate.ps1.  The last is for PowerShell 
which you can install on Ubuntu, though I'm not sure why. 

I used to use tcsh but when the Linux world seemed to prefer bash I 
switched. I never did anything with fish.

On Windows you get activate.bat, deactivate.bat, activate, and 
Activate.ps1 and they are in the Scripts subdirectory. 

After you activate a venv the prompt will change to something like

(numerical) rbowman@kropotkin:
(fastapi) rbowman@kropotkin:

and on deactivate it goes back to 

rbowman@kropotkin:

The site=packages for the numerical venv include matplotlib, seaborn, 
torch, sklearn etc and their dependent packages.  The fastapi packages are 
completely different, fastapi, pydantic, uvicorn, and so forth. Try 
running the fastapi script in the numerical environment and you won't get 
past 

from typing import Union
from fastapi import FastAPI
from pydantic import BaseModel

That's what virtual environments are all about. Try installing all those 
packages in the global site-packages and you get the mess Lawrence 
mentioned, and it won't matter if you're on Linux, Windows, BSD, or any 
other OS. The clueless can screw any OS up.
