When I am trying to download the courses, I am getting a connection reset message .
for e in chosen_courses:
course_title = courses_t[int(e)-1]
print(e + ' '+course_title)
lecture_homepage = homepage + courses_u[int(e)-1]
os.chdir(initial_dirname)
create_download_dir(courses_t[ int(e)- 1])
a,b,c = enumerate_lessons(lecture_homepage)
lessons = zip(a,b,c)
download_videos(lessons)
#create_m3u_playlist(course_title)
download_quiz(lessons)
download_html(lessons)
os.chdir(initial_dirname)
print('download finished')
Executing the above cell gives me this stacktrace and a strange ConnectionReset error.
Is it implemented by Coursera?
