The Volatile GPU-Util is always 0, in examples/imagenet

[wangxianrui]

I run the example of imagenet in https://github.com/pytorch/examples/tree/master/imagenet, althougt I can run it successfully, but it is slow, and the Volatile GPU-Util is always 0 with command 'nvidia-smi'

did you try increasing the num-workers ?
maybe something like 16 ?

Yes, I have tried, but it doesn't work.

[surgan12]

what is the batch size that u r using ?

[wangxianrui]

what is the batch size that u r using ?

256

[surgan12]

I sort of had the same problem but increasing the batch size and num workers did the trick for me

[wangxianrui]

so what is the num-workers and batch-size you set?

[surgan12]

i set the batch size to something around 500 and num_workers as 16

Given that the power consumption is 70W, I would say the GPU is actually computing.
I think is a bug of nvidia-smi, and I have the same behaviour.

Hello, perhaps you know how to download the ImageNet dataset for this program to use?
Please tell me, thank you very much!

[JiyueWang]

Does anyone solve this problem?
