Is there a way to support multithreading with sweeps for hyper parameter tuning. (like sklearn GridSearchCV ‘n\_jobs’ parameter). ---

can you just launch multiple wandb.agents with the same sweep id (passed from outside) in different threads? the sweep controller, i guess, will orchestrate that they get different parameter sets ---

Hello @vikrant17 , We’ll look into this if W&B can support this one, let us check things on our end first and will get back to you. ---

Hi @joana-marie , I wanted to do a random search for the hyperparameters quickly. I wanted to know if there is way to use all the cores of the system to do the hyperparameter sweeping (like the sklearn CV methods allow). The only solution I have come across is to run the sweep via multiple processes using the same sweep id. ---

Any solution to this? ---

Hi @vikrant17 , You will need to use parallelized agents [Parallelize agents](https://docs.wandb.ai/guides/sweeps/parallelize-agents) and you can’t run multithreading to parse through the different hyperparameter combinations. ---

Hi @joana-marie I was able to run the sweep in parallel using the joblib package as multiple process. Although this could be done using the sweep id as mentioned by you, I wanted something that could automatically use separate cores automatically to perform each run for the sweep in parallel. That way I don’t have to open new terminals and manually run the agent. Anyways, thank you. ---
