This error message typically occurs when you are trying to use the `plt` module from Matplotlib, but you haven't imported it yet. To fix this error, you need to import `matplotlib.pyplot` by adding the following line of code at the beginning of your script:
```
import matplotlib.pyplot as plt
```
This will allow you to use the `plt` module throughout your code.
