Converting Dataframe to Numpy Array

Question

I have 3 columns in my df

How can i convert this to a matrix? I tried

numpy_matrix=df.as_matrix()

but this doenst give a matrix

Don't use a matrix, they have a special meaning with numpy and their usage is not advised. — Matthieu Brucher, Mar 04 '19 at 15:10

In pandas 0.24.0+, it is recommended that you use to_numpy. The function as_matrix was deprecated in pandas 0.23.0.

df.to_numpy()

To convert a pandas dataframe (df) to a numpy ndarray, use this code:

df = df.values

df now becomes the numpy ndarray:
