How to run python through the terminal using conda installation

I have created a Python environment and activated it using conda. Now I want to run a simple script that just imports Numpy via python script.py

import numpy as np
print(np.zeros(4))

But I get the following error

No module named 'numpy'

Which I don’t understand since running conda install numpy gives

All requested packages already installed.

Also running pip install numpy gives

Requirement already satisfied: numpy in /Users/anaconda3/lib/python3.12/site-packages (2.2.1)

So I am not sure what is happening. Perhaps it is not using conda version when I run python script from the terminal? How can force it to do so?
