Unable to reproduce PyTorch tutorial results

I installed cuda drivers + pytorch for my system. To ensure, everything is working as expected, I ran the Transfer Learning tutorial from the Pytorch website. However, I am unable to reproduce the results consistently. For some runs, I get the accuracy as per the tutorial. Other times it is off by 1%. These are my results:

Training complete in 0m 54s
Best val Acc: 0.934641

Training complete in 0m 46s
Best val Acc: 0.954248

I ain’t able to reproduce even while running the code on CPU.

Training complete in 3m 58s
Best val Acc: 0.941176

Training complete in 1m 51s
Best val Acc: 0.954248

On another CPU run, here’s what I got:

Training complete in 4m 1s
Best val Acc: 0.934641

Training complete in 1m 48s
Best val Acc: 0.954248
