运行结果总是显示:'float' object cannot be interpreted as an integer

图片说明
代码如下:

```import numpy as np
import pandas as pd
import scipy.fftpack as sf
data=pd.read_csv('Calculator Expressions Plot 6.csv')
Fr=data['fr2'].values.reshape(121.1001)
A=abs(sf.fft2(Fr))
x,y=A.shape
B=A/x/y*2
B[0,0]/2
shift_B=sf.fftshift(B,axes=1)
if y%2==0:
    N=y/2
else:
    N=(y+1)/2-1
p=4
space_n=10
n1=int(N-space_n)
n2=int(N+space_n)
FFT2_B=shift_B[0:13*p:p,n1:n2+1]
Y=[]
for i in range(13):
    for j in range(21):
        X=[j,i,FFT2_B[i,j]]
        Y=Y+X
arr=np.array(Y).reshape(273,3)
AP=arr.tolist()
from pyecharts import Bar3D
bar3d = Bar3D("3D zhu zhuang tu",width=1600,height=800)
x_axis = ["-10","-9","-8","-7","-6","-5","-4","-3","-2","-1","0","1","2","3","4","5","6","7","8","9","10"]
y_axis = ["0","1f","2f","3f","4f","5f","6f","7f","8f","9f","10f","11f","12f"]
range_color = ['#313695','#4575b4','#74add1','#abd9e9','#e0f3f8','#ffffbf','#fee090','#fdae61','#f46d43','#d73027','#a50026']
bar3d.add("dian ci li fft zhu zhuang tu",x_axis,y_axis,AP,is_visualmap=True,
          visual_range=[0,2500],
          visual_range_color=range_color,
          grid3d_width=200,
          grid3d_depth=80,)
bar3d.render()

错误的位置是第六行:
data=pd.read_csv('Calculator Expressions Plot 6.csv')
Fr=data['fr2'].values.reshape(121.1001)

csv文件中数据是浮点数,data和Fr必须是整数吗?

麻烦各位前辈解答一下。
