在学习pyradiomics官网示例代码RadiomicsExample时报错runtimeerror

在设置数据这一步总是报错,有没有小伙伴也遇到过呀,这怎么解决啊,啊,苦恼死了
import os
import SimpleITK as sitk

from radiomics import getTestCase

imagepath_1, labelpath_1 = getTestCase('brain1')
imagepath_2, labelpath_2 = getTestCase('brain2')

image_1 = sitk.ReadImage(imagepath_1)
#label_1 = sitk.ReadImage(labelpath_1)
#image_2 = sitk.ReadImage(imagepath_2)
#label_2 = sitk.ReadImage(labelpath_2)

报错是这样的
