You must be familiar with this message 🤬: RuntimeError: CUDA out of memory. Tried to allocate 20.00 MiB (GPU 0; 7.93 GiB total capacity; 6.00 GiB already allocated; 14.88 MiB free; 6.00 GiB reserved in total by PyTorch) While it's easy to see that GPU memory is full, understanding why and how to fix it can be more challenging. In this tutorial, we'll go step by step on how to visualize and unders
