No module named streamlit

I have installed streamlit on my windows 10 with the latest version of anaconda with pip. I confirmed the installation by launching streamlit using streamlit hello. But when i want to import streamlit in vs code or idle shell, it gives this error:

Traceback (most recent call last): File "C:\Users\HP\AppData\Local\Programs\Python\Python310\website2.py", line 1, in import streamlit as st ModuleNotFoundError: No module named 'streamlit'

Here is one approach to get started with streamlit on windows.

1. Create a folder say c:\myproject
You can do this on other drives.

2. Open your powershell and cd or Change Directory to that folder

3. PS c:\myproject>python --version
to see if you have python installed and what version

4. PS c:\myproject>python -m venv venv
Creates venv folder for your virtual environment under
c:\myproject with python installed.
You only need to create this once.

5. PS c:\myproject>./venv/scripts/activate
That will activate your virtual environment, always do this if not
yet activated.

6. (venv) PS c:\myproject>python -m pip install -U pip
to update your pip

7. (venv) PS c:\myproject>pip install streamlit
That will install streamlit in the venv folder.

You can now open c:\myproject with your vs code or
other editor and write codes in say app.py.

8. (venv) PS c:\myproject>streamlit run app.py
to run your streamlit app

Note on (venv) that means your virtual environment is active. Only install lib/modules when venv is active. Installed modules will be found in the venv folder. Also run streamlit when venv is active.

Looks like you have installed python with anaconda in a different path/ virtual environment and you already have python installed in your PC (program files). And also you have installed streamlit in the virtual env. You then you have to activate the virtual environment first by conda activate <virtial_env_name>. If you can't remember the name you gave to the vir_env while creating, you can list available vir_env names via conda.

The IDLE you are trying to import streamlit should be the idle installed along with the default python interpreter you are using. In vs code also you are using the default one. So you have to activate virtual env via the vs code terminal or vs code command pallet by hitting ctrl+shift+P and typing python select interpreter

Make sure you choose the correct Python interpreter: ctrl+shift+P on vscode to open the command bar and type in "Python Select Interpreter". Search for ananconda or conda and you should have a list of available interpreters. Choose the one suitable to your needs.
