[D] How often do you run into reproducibility issues when trying to replicate papers?

A viral discussion on r/MachineLearning reveals a systemic reproducibility crisis in AI research. Researchers detail frequent, unexplained failures to replicate published results from papers like "Machine Theory of Mind" (ICML 2018), despite careful parameter matching. The issue, reported as widespread by multiple labs, highlights gaps in documentation, code quality, or undisclosed hyperparameters that prevent verification of claimed breakthroughs, slowing scientific progress.
