DL libraries are pretty complex and sparsely documented which can make for a painful learning experience, even if you already know C++. Maybe go and learn some graphics programming with C++. You’ll encounter plenty of matrix manipulation, shaders, OpenGL and the like, and there are plenty of really good learning resources and the immediate visual feedback makes for a compelling experience. Then you can return to DL and understand where things are coming from. Make sure you learn how to use a debugger. You’ll need it.
