Question about using GPU

[coregosu12]

I am using NVIDEA Geforce GTX 750 Ti, and CUBA.

But my code says that The computer is using NVIDEA but the task manager says that the computer isn't using GPU, and only using CPU. I have a question on it.

1. 'CPU using' rate is nearly 100% on task manager, and I will use faceswap training for 4₅ days. Can the program break my computer? (Fire)

2. How to make my computer to use GPU?

3. Using GPU makes the processing speed higher?

Following is my code. Thank you for checking.

For 1, your computer should shut itself down before it catches fire. If your machine is well ventilated and well powered, you should be fine.
