I've used different deep learning frameworks, but PyTorch has been my favorite so far. It offers a lot of flexibility and makes prototyping models a breeze. The library is well-documented and the examples provided are extremely helpful. The community is active and always ready to assist with any issues. The only thing I wish for is better performance optimization, especially when dealing with large datasets. Nonetheless, PyTorch is a reliable and highly recommended framework.
