OMP: Warning #96: Cannot form a team with 48 threads, using 2 instead.
OMP: Hint Consider unsetting KMP_DEVICE_THREAD_LIMIT (KMP_ALL_THREADS), KMP_TEAMS_THREAD_LIMIT, and OMP_THREAD_LIMIT (if any are set).

Prediction-loss E(||U-Uhat||) and variance-loss E(||Uhat-Uhat'||) should ideally be equally large --
consider training for more epochs if there is a mismatch.
