y=np.empty(n_tr)

print(permutation)
print(labels[permutation])
save_data=pd.DataFrame({'name':permutation,'invasive':labels[permutation]})
save_data.to_csv('C:/Users/49691/Desktop/数据集/b.csv')
fork,vinenumerate(np.random.permutation(n_tr)):
print(k,v)
path='{0}{1}.jpg'.format(trainpath,v)
tr_im=io.imread(path)
x[k]=transform.resize(tr_im,output_shape=(224,224,3))
y[k]=float(labels[v-1])
