如何解决读取CSV文件
import numpy as np
import pandas as pd
df = pd.read_csv('/content/Glassdoor Reviews.csv',encoding='latin1',error_bad_lines=False,sep=';')
df.head()
nullcheck=df.isnull().sum()
print(nullcheck)
count=df['Category'].value_counts()
print(count)
from sklearn.model_selection import train_test_split
X = df['Review'] # this time we want to look at the text
y = df['Category']
X_train,X_test,y_train,y_test = train_test_split(X,y,test_size=0.2,random_state=20)
