Error in Python script “Expected 2D array, got 1D array instead:”?

Question

I\'m following this tutorial to make this ML prediction:

import numpy as np
import matplotlib.pyplot as plt
from matplotlib import style

style.use(\"ggplot\         


        

Answer 1

I was facing the same issue earlier but I have somehow found the solution, You can try reg.predict([[3300]]).

The API used to allow scalar value but now you need to give a 2D array.
