Hungarian Matching Algorithm
What is the Hungarian Matching Algorithm?The Hungarian Matching Algorithm is a bipartite matching algorithm that solves the assignment problem in polynomial time. The assignment problem assumes there are $n$ tasks that must be assigned to $n$ agents, with no duplicate assignments, in such a way that the total cost of the assignments is minimized. Problem DefinitionGiven an $n \times n$ cost matr..

RuntimeError: Expected to mark a variable ready only once. This error is caused by one of the following reasons: 1) Use of a module parameter outside the `forward` function. Please make sure model parameters are not shared across multiple concurrent forward-backward passes. or try to use _set_static_graph() as a workaround if this module graph does not change during training loop.2) Reused param..
