How fix any erros whuch i get creating im2rec

[jasperDD]

from skimage import io

test='C:\Users\Admin\Desktop\test.lst' # folder where must be my test.lst

test='C:/Users/Admin/Desktop/test.lst'
DataSet='C:/Users/Admin/Downloads/mypic/'

data_iter = mx.image.ImageIter(
batch_size=4,
data_shape=(3,816, 1232),
label_width=4,
path_imglist='C:/Users/Admin/Desktop/test.lst',
path_root='DataSet')

for data in data_iter: d = data.data[0]
break

Error

for data in data_iter: d = data.data[0]
... break
File "", line 2
break
^
SyntaxError: invalid syntax

=================================

then

import numpy as nd
img =nd.transpose(d,(0,2,3,1))

===== Error

train_iter = mx.image.ImageIter(

============i get next errors
