You can master Computer Vision, Deep Learning, and OpenCV - PyImageSearch
When it comes to working with deep learning + Python I highly recommend that you use a Linux environment. Deep learning tools can be more easily configured and installed on Linux, allowing you to develop and run neural networks quickly.…
