WebNote. In solvers which weight_decay_is_fused() returns true, the weight decay is not immediately performed when called. Instead, the specified decay_rate is stored in the solver instance, and lazily evaluated when update() method is called. The stored decay rate will expire after update() and revert to 0 or a default value specified at initialization of Solver … WebSymPy Solvers - Since the symbols = and == are defined as assignment and equality operators in Python, they cannot be used to formulate symbolic equations.
