This article describes memory management in Python 3.6. If you are interested in GC details, you can read my article aboutGarbage collection in Python. Everything in Python is an object. Some objects can hold other objects, such as lists, tuples, dicts, classes, etc. Because of dynamic Pyt...
In most situations, however, it is recommended to allocate memory from the Python heap specifically because the latter is under control of the Python memory manager. For example, this is required when the interpreter is extended with new object types written in C. Another reason for using the ...
Using Python Data Types Instead of 1-D Tensors In our training loop, we frequently aggregate values to calculate metrics, with the most common example being the update of the running loss during each iteration. However, if this is not done carefully in PyTorch, it can result in excessive m...
