Missing argument in MNIST example

[danperazzo]

📚 Documentation

Hello everyone, I have been reading the MNIST_README.md to run its example and I noticed an issue.

It mentions that, to run it, we have to use:

python mnist.py --device=cpu -n=15 --lr=.25 --sigma=1.3 -c=1.5 -sr=0.004

However, there is no argument sr on the code, and the results are too different from the reported ones. Thanks for the attention!

Hey danperazzo,

Thanks for flagging this! Labelling is at bug, will investigate.

'-sr' means poisson sampling rate, but the code use '-b' batch size, so just change -sr=0.004 to -b=240, for example.
