After loading the model parameters, the simulation code is stuck

After loading the model parameters, the code is stuck and no training information is output. What could be the cause?

Hi @Mickeyyyang ! Thanks for having interest in our project!

Looking at your tmux, my first guess would be that mongoDB hasn't really started, so both trainer and sampler are waiting to connect to the database. I recommend double-checking the mongo config and maybe trying to connect to it manually to make sure the DB is up and running
