After taking instructor Park Jo-eun's course at Naver Boost Course - I learned the basics of PyTorch and TensorFlow and then proceeded. It's easy and good for non-majors to listen to, and it's 90% focused on project practice, so I recommend it... It was also good for easily understanding the concepts of deep learning, which I had studied with difficulty. It would be good if you also provided the marketing analysis that you do on YouTube as a lecture.
