Hello, I recently run your program code:python main_vec.py --exp_name coop_navigation_n6 --scenario simple_spread_n6 --critic_type gcn_max --cuda , to test the coop_navigation model. The parameters are all default. However, during the test, it is found that all six agents do not cover landmark, and the success rate of coverage is not given in the paper. What is the success rate of your model? Is there something wrong with the training? Look forward to your reply
