  <p>1.2 Both. CUDA cores are great for speeding up matrix multiplication calculations which are big part of neural network inference. This process is used both during training and execution.</p>
  <p>1.3 It is CUDA, regular GPUs don't have any other processing units than CUDA that could be beneficial to DL. Modern card though have also tensorcores that are specifically designed for speeding up DL calculations.</p>
  <p>1.4 Let's say CUDA programming language is way to communicate with CUDA cores.</p>
  <p>1.5 You don't have to because popular frameworks such as PyTorch or Tensorflow already have it implemented on its lower level of architecture. You need language such as Python to use these frameworks though. But of course you could learn if you have a lot of time and are very passionate about low-level deep learning architectures.</p>
  <p>2.1 To my knowledge it is only NVIDIA's series of embedded products such as Jetson Nano which are SBC (single board computers) that, contrary to for example popular Raspberry PIs, also have some CUDA/tensorcores which makes them more suitable for DL models.

  <p>2.2 I don't think so, although there is some software/code/frameworks that helps you implement your models on these devices. But you still need to train you model with pytorch or tensorflow first.</p>
  <p>3.1 YOLO generally is just an architecture, more like theoretical model with particular settings but not piece of code or implementation.

I am pretty sure that if you look deeper you will find some different YOLO's implementation that do not use VS, even coded from scratch.

  <p>3.2 Yes. Try ultralytic's model that I believe uses only pytorch: <a href="https://github.com/ultralytics/yolov5" rel="nofollow noreferrer">https://github.com/ultralytics/yolov5</a>. I used this one and don't remember installing anything else besides regular python libs and pytroch.</p>
  <p>4.1 Different frameworks are coded in different ways and use different commands. If you code one model in tensorflow it is not gonna work in darknet or pytorch because they use different syntax, functions and classes. Maybe you would be able to find some frameworks that work as universal model exporters/importers, that can export Tensorflow model to some intermediary format and later import it in darknet, but I have no knowledge on them. Also keep in mind that DL models usually need some additional functions that preprocess input data and later postprocess output data to a usable for human form that usually come with given implementations or frameworks.</p>
  <p>4.2 Yes, they depend on the frameworks and particular implementations of given model. YOLO can have multiple implementations within one framework and it all depends on authors of the particular implementation how the interface is gonna be.</p>

  4.1 amAbout the frameworks: As far as I know when it comes to Yolo (for example), it can be trained on different frameworks.
