Hello,

when I train a neural network it takes about 5-7 mins of computing time on my pc. When I compute it via experiment manager (bayesian optimization) it takes an hour to compute the network with the same stats... why such a huge difference?

Thanks in advance

Best

I have the same problem. The time is 2 times longer even worst! I wonder how to solve this problem?

I am also having the same problem even with Shallow Neural Networks! What could be the cause of this?

But you understand, right, that when you use the Experiment Manager, your network is being retrained multiple times with different sets of hyperparameters? If as part of its search, the EM needs to test 10 sets of parameters, each requiring 5-10 min. of training, it makes sense that the whole exercise would be an hour long or more.

That is not the reason. The speed is just very low even when single experiment is conducting!

But the training time will be different for every experiment, depending on the values of the hyperparameters. Have you really done a side-by-side comparison of the exact same training experiment, both with the same choice of hyperparameters?
