No constructor in yaml for StackedDenoisingAutoencoder

[Isaac Gerg]

Trying this:

    model: 

        !obj.pylearn2.models.StackedDenoisingAutoencoder {

        autoencoders : [

            !obj:pylearn2.models.autoencoder.Autoencoder {

                nvis : 1296,

                nhid : 3000,

                act_enc: 'sigmoid',

                act_dec: null,

                tied_weights : 'False' } ],

        corruptor: !obj.pylearn2.corruption.DropoutCorruptor { corruption_level : 0.5}

                

    },

But am getting told 

yaml.constructor.ConstructorError: could not determine a constructor for the tag '!obj.pylearn2.models.StackedDenoisingAutoencoder'

in "<string>", line 26, column 9:

!obj.pylearn2.models.StackedDeno ...

Sounds like there is no registered constructor in yaml for StackedDenoisingAutoencoder.

This should be !obj:pylearn2.... with a ":" after "!obj", not a ".".

Thanks for that catch Pascal, this fixed my issue.

It seems that show_weights.py doesnt work for pkl files generated from StackedDenoisingAutoencoder.  Is this correct?  How do I visualize the weights?
