Question

这是一个可运行的代码段，在我的计算机上生成错误。我遇到了这个错误（ValueError：零大小的数组，以最小化没有身份的缩小操作）。

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt

import seaborn as sns
from pandas import DataFrame



data=pd.read_csv(r"C:\Users\yavuz\Desktop\Pokemon.csv", sep='\t', 
engine='python')

f,ax=plt.subplots(figsize=(18,18))

sns.heatmap(data.corr())

**Error**
