Hi，

Q1: The constraints for the training dataset show "Average bandwidth must be between 10 and 10000". I changed the "max_avg_lbda = 1000" parameter in quickstart notebook to "max_avg_lbda = 10000". The time taken to generate data has increased from about 10 minutes to 4 hours. I wonder if there is any problem.

That behavior is expected. The execution time of the simulator is proportional to the number of packet events in the network. If you increase the generated traffic (max_avg_lbda) while keeping the packet size distribution, the number of packets —and therefore the execution time— will increase.

Q2：Whether the submitted model for testing can be the best model generated in the training process. Or must be a model after 20 epochs of training.

You can select the best model from those generated during training.

Could you please advise?

Thanks， Mei _______________________________________________ Challenge2022 mailing list Challenge2022@mail.bnn.upc.edu https://mail.bnn.upc.edu/cgi-bin/mailman/listinfo/challenge2022
