Open Settings and add the following key:

"pythonPath": "/usr/bin/python3",

virtualenv --python=/usr/bin/python3 venv

enable virtual env

source venv/bin/activate

and then give the command

code .

so the visual studio code will open all files in that folder using virtualenv's python as an interpreter.
