I fixed an unrelated bug when running that script:
rdevon/cortex@1f566bc

but I was unable to replicate your error. I noticed that you're using Theano-0.9.0dev0. How did you install Theano?

[AojunZhou]

Thanks, I have installed Theano, and I can run test RMB_mnist Successfully, I will try it again tomorrow.

hi,

sorry，i still not solve this problem, when I debug the code，I find the bug in utils/op.py line 297 updates=gsup+extra_ups

Because type(gsup)=<type 'list'>

maybe this issue caused by Theano.

thanks

So you can run rbm_mnist but not rbm_ni? That's strange: the code is almost the same.
I cannot reproduce your error, but I have a hunch what's going on. I've pushed a small change:
rdevon/cortex@e53b54e
that casts updates as an OrderedUpdates. Hopefully that fixes it.

[AojunZhou]

(Pdb) updates = theano.OrderedUpdates(updates)
*** TypeError: TensorType does not support iteration. Maybe you are using builtin.sum instead of theano.tensor.sum? (Maybe .max?)

sorry，the new bug occured，and i cannot run rbm_mnis now.

thanks

Interesting. Can you do 2 things for me, as I cannot reproduce these errors:

1. provide the full traceback as when you run the script.
2. provide the value of updates from within Pdb

Thanks

[rdevon]

Also, can you confirm your version of Theano?

[AojunZhou]

hi,

sorry,I reply is too late

the attachment contains the error
