Can't execute torch from my conda environement

Hy everyone,
I have installed torch in an environement called faster,
and i activate it with conda activate faster
but when i execute my code, it display that there is no module named torch,
it seams that it execute from the base conda not form the environement,
1- is there anyone who can tell me how to change it to execute from the environement?
2- Is there a difference between torch and pytorch?
there are the packages installed inmy envs:

Are you executing the script in the terminal directly of in a Jupyer notebook?
Sometimes, the default Python environment in a notebook is not set to the right one, so you might need to change it inside the notebook.

If you are using the terminal directly, do you see the environment name in front of the current user?

thanks for your replay, you are reight vs code use an other environement to execute the code, it work now.
and please what is the differance between torch and pytorch in the execution?

pytorch would be the package name, while you would have to use import torch inside the script.
These are just names for the same package.
