问题
I installed tensorflow-gpu on win10. I am trying a keras trainning example to test the GPU computing. I loaded all the cuda successfully but show the following:
Train on 60000 samples, validate on 10000 samples
Epoch 1/100

I dont know what does the last sentense mean that can not identify NUMA node. Also when I check nividia-smi, it shows the following:

No running process found when I was training the data. Did I setup everthing correctly in this case?
