Hi @NoOneUST!
Thank you for your interest in our work!
The differentiable NAS formulate the search space as the model (e.g. convolution weights) and architecture (determines which operator to use in each cell). During the search, the model parameters and the architecture parameters are alternatively optimized. Thus, we need both of them.
To enable the multi-gpu training, you have to at least wrap the nn.Module
into nn.DataParallel
(which I did not implement here).
Another Question, when I try to use multi-process-evaluation, no matter I input device=[3,5,6,7] or [0,1,2,3] when CUDA_VISIBLE_DEVICES=3,5,6,7. The occupied GPU is always only 0. How should I solve it?![image](https://user-images.githubusercontent.com/48406286/77666222-a7065900-6fbb-11ea-8266-9150a289fa11.png)
