熊猫相关空DF

Question

我想计算熊猫DF ['text']的同一列之间的相关性，我总是得到一个空的数据框，这是我的代码：

import codecs
import pandas as pd

with codecs.open("glv.txt", 'r', encoding='utf8') as f:
    text = f.read()   
    print(text)
    lines = text.split("\n")
with codecs.open('glv2.csv', 'w', encoding='utf-8') as f2:
    for line in lines:
        f2.write(str(line)+ "\n")
        f2.write(line)
        f2.write("\n")
df = pd.read_csv('glv2.csv',sep='delimiter', names=[ "text"], header=None, error_bad_lines=False)

df.corr(method ='pearson')
