Are there some useful demo for DBM using pylearn2?

[Chris Yeh]

Well, now I want to train a DBM using pylearn2...I am trying to study something about DBM.

But I am not quite familiar with pylearn2. The lisa_lab's codes is too difficult for me to understand...

Now I can use the pylearn2/scripts/tutorials/dbm_demo/train_dbm.py to learn how to train a dbm, but I am totally confused about how to show the results and something else.

For example, how can I predict some data using this model? 

And, I try to use pylearn2/scripts/dbm/show_negative_chains.py to show something, but the console printed

 "'DBM' object has no attribute 'dataset_yaml_src'

"

Such a mass, could someone help?
