Improper batch size selection causes memory errors or slow convergence in PyTorch

5/10 Medium

Selecting an inappropriate batch size in PyTorch training leads to either out-of-memory crashes (too large) or noisy gradient updates and slow convergence (too small). There is no automated guidance or tooling to help developers find an optimal batch size, requiring manual trial-and-error experimentation.
