Chapter 3: Rerunning the notebook

For some reason when I download and rerun the Chapter 3 notebook locally the results of the SGD classifier are different. I have not modified any of the code. For example, I get different outputs for the decision function and my predictions for `some_digit` for multiclass classification return 3 not 5. I also see a different PR curve. See the attached image.

I was under the impression that if we used the same random seed the SGD classifier results would be reproducible? Does anyone know why I might be getting different results?
