from skimage import io import mxnet as mx   test='C:/Users/Admin/Desktop/test.lst'# folder where must be my 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]     if some_condition_is_True:         break       import numpy as nd img =nd.transpose(d,(0,2,3,1))

after it, i get error

Error:

this error is not produced by this code.
Check the actual code that you are running.

Also if some_condition_is_True: - some_condition_is_True is just a placeholder, you need to replace it with actual condition that will break you out of the loop
