我正在尝试用数字集成以下数据：

如下所示，我从csv文件中读取了此数据集。这是我的代码：
import pandas as pd
from scipy.integrate import trapz, simps
root="my/root/dir"
df = pd.read_csv(root+r"simps.csv")
print(trapz(df["t"], df["y"]))
print(simps(df["t"], df["y"]))
trapz返回一个值(-9.5865055e-10(，而simps返回nan和以下错误：
anacondapathscipyintegratequadrature.py:324: RuntimeWarning: divide by zero encountered in true_divide
h0divh1 = h0 / h1
anacondapathscipyintegratequadrature.py:326: RuntimeWarning: divide by zero encountered in true_divide
y[slice1]*hsum*hsum/hprod +
anacondapathscipyintegratequadrature.py:327: RuntimeWarning: invalid value encountered in add
y[slice2]*(2-h0divh1))
anacondapathscipyintegratequadrature.py:326: RuntimeWarning: invalid value encountered in add
y[slice1]*hsum*hsum/hprod +
为什么会出现此错误？
一个非常愚蠢的错误：我交换了x和y。Simps需要y作为的第一个参数
