The package is not installed in the running Python. The PyPI name is `undetected-chromedriver` (dashes) and the import is `undetected_chromedriver` (underscore). Run `python -m pip install undetected-chromedriver` and the import works.

## The error

```text
ModuleNotFoundError: No module named 'undetected_chromedriver'
```

## Fix it

1. **Install undetected-chromedriver**

```
python -m pip install undetected-chromedriver
```
Expected: `Successfully installed undetected-chromedriver-...`.

2. **Confirm**

```
python -c "import undetected_chromedriver as uc; print(uc.__version__)"
```
Expected: prints the version.

## When this applies

- any `import undetected_chromedriver` fails naming the module
- a fresh env following a scraper tutorial

## When it does NOT apply

- `SessionNotCreatedException ... only supports Chrome version N` is a driver/version mismatch after import
- `cannot find Chrome binary` means Chrome itself is missing

## Compatibility

undetected-chromedriver 3.x. Needs Python 3.8+ and selenium installed (it is a selenium dependency).

## Why it happens

The package was never installed into the active interpreter. The dash/underscore difference between the PyPI name and the import name trips up `pip install undetected_chromedriver` guesses (underscore does not exist on PyPI).

## Edge cases

- `pip install undetected_chromedriver` (underscore) fails. Use the dash form.
- undetected-chromedriver 3.x needs selenium 4. If your env pins selenium 3, upgrade selenium first.
