读取文件时出现FileNotFoundError

Question

帮助，有人知道为什么它会给我这个错误吗？

import tensorflow
import keras
import pandas as pd
import numpy as np
import sklearn
from sklearn import linear_model
from sklearn.utils import shuffle


data = pd.read_csv("student-mat.csv", sep=";")

data = data[["G1","G2","G3","studytime","failures","absences"]]

print(data.head())

Traceback (most recent call last):
