Some questions about training a bot

[infinitycr]

I change the network to 64*5 and start 2 clients . One client is running start_server.sh and start_client.sh simultaneously, and another one is running start_client.sh. From the log file I find that there are over 4000 selfplay games after running 40 hours. However, .I cannot find anything about training information. I want to know when will the training start?

Hi @infinitycr , thanks for your interest! The training will only start once a sufficient number of selfplay games are gathered. The default setting in the start_server script will require roughly 12k-20k games. To scale down this requirement, you can decrease q_min_size.

@jma127 I find the q_min_size in the script file is 200, so 200 means 12k-20k selfplay games? Could you please explain specificly about the relationship of q_min_size and selfplay games?

[jma127]

There are 50 queues that store the games, and q_min_size 200 means that each queue must have 200 games before any training will start.

@jma127 I'm really appreciated for your reply! I'm confused about some logging information.

These logging information come from the start_server.sh. What's the meaning of '5 valid selfplays'? Does that mean there are only 5 valid selfplay games in 4000 games performed by the client?
