SAM2ImagePredictor returns significantly worse results than provided demo

I was able to successfully install and run SAM2 on two different windows machines, as well as trying a linux installation with WSL on one of them. I also created a .py file that copies the code provided in "image_predictor_example.ipynb" exactly. One of these computers is a weaker laptop, while the other one has an NVIDIA GeForce RTX 3070.

In all 3 of my sam2 installs/environments, my demo code returns very poor masks, with an example seen below.


Any help with solving this would be greatly appreciated, as far as I can tell I have followed all installation steps.
