If you want to practice on the map yourself, then you will have to remove any bots from this map.
To do this, you only need to do three things:
1) Create a server with bots.
2) Open the console and register the bot_kick command in it.
3) All AI players will kick and you will remain on the map alone.
The bot_kick command itself can execute 2 actions at once:
1) Kick all the bots after writing the command in this form.
2) Kick one bot, if you add after that command his name.
