The parameter no longer possesses the
optimizer_classattribute; instead, it has been updated tooptimizer_classes. However, the current implementation of theEmbeddingStorageEstimatorstill relies on the outdatedoptimizer_classattribute to determine whether the parameter includes an optimizer. As a result, theEmbeddingStorageEstimatorfails to estimate the storage requirements for the optimizer, leading to CUDA out-of-memory errors during training.
