ynd / cae.py Goto Github PK

Hi guys,

I cant get the code to run on a minimal example - see interactive python dump below. I have the strong feeling that I'm just missing something basic, here :)

Cheers and thanks

mycae=cae.CAE(n_hiddens=3,batch_size=1)
x=numpy.matrix([[0,0,0,1],[0,0,1,1]])
mycae.fit(x,verbose=True)
Traceback (most recent call last):

How to run the cae.py? how to use the function sample()? and in function _jacobi_loss() has a Error:AxisError: axis 2 is out of bounds for array of dimension 2.
Please, THank you~
