converting dataframe to int numpy array

[snippsat]

Use reaf_csv().

>>> import pandas as pd
>>> import numpy as np

>>> df = pd.read_csv("sample.txt", header=None, sep=',')
>>> df = df.to_numpy()
>>> df
array([[1, 2, 3],
       [1, 2, 4],
       [1, 2, 5]], dtype=int64)

>>> df[0]
array([1, 2, 3], dtype=int64)
>>> df[0][2]
3
>>> type(df[0][2])
<class 'numpy.int64'>
