I have followed the exact steps from the tutorial. Tried with base learning rate 0.01 (default value) and 0.001 (based on the tutorial screenshot), but both didn't get better accuracy. Also it took almost 25 minutes to train.

Exactly same issue here

Not sure what you're hitting. Is this retraining the existing models or from scratch? I'd advise moving on to retrain, since doing the first from-scratch run is not going to produce anything useful regardless (not enough data).

It's possible that something has changed (version issues upstream) with digits or caffe or something since I wrote this, I haven't re-run the steps for a while.

I'm in the process of updating the docs to use TensorFlow at the moment, which I hope to get done this summer.
