Sorry if my question is stupid, I am completely new to this. But, why exactly is a Weights and Biases account needed? I thought the training is running in vast.ai
Vast.ai is a cloud host similar to aws ec2 instances. Weights and biases is a cloud thing that you can track your model run (like how well is it doing so far, what is the current learning rate, etc). It shouldn’t be required - but I guess the training code was written assuming you have it
