How to set framerate in Pygame?
So in response to my question (How to continuously move an image smoothly in Pygame?) I was told to set my framerate in order to do my animation. But no matter where I place it, clock.tick(60) does nothing. I do clock = pygame.time.Clock() BTW. So how do I do this? I have researched and found this (pygame clo…
Sticky index reference while inserting into 2D list in Python
While attempting to implement a function that produces all permutations given a list of integers, I’m seeing this behavior where the inserts are not occurring as expected. My code: When calling permute([1, 2, 3]) I’m expecting the perms to grow like: However, by the second iteration of the interio…

How do I check if a tokenizer/model is already saved
I am using HuggingFace Transformers with PyTorch. My modus operandi is to download a pre-trained model and save it in a local project folder. While doing so, I can see that .bin file is saved locally, which stands for the model. However, I am also downloading and saving a tokenizer, for which I cannot see any…
