Hi, Mansur.
Please realize that the mentors are volunteers here: we do not get paid to do this. We are happy to answer questions in writing in the public forum, so that the information may benefit other current and future students, but we don’t provide the type of individualized video tutoring that you are requesting. At least I personally do not prefer to do that, but you may get lucky and someone else will see this thread and contact you and offer to help in that way.
You didn’t answer my question about whether you had read this thread that I linked earlier.
Is this your first class in the DLS series? Or did you previously take DLS Course 1 and Course 2?
If you have not been through the TensorFlow Introduction in Week 3 of DLS Course 2, that might explain why you are having problems here. But note that you really have not given us any details about which parts you are having trouble with.
How about trying to ask one specific and concrete question here in writing about something that is puzzling you and seeing how that goes?
Regards,
Paul
