CDBN, Dataset with size of 8000 run into failure

[h-bahrami]

Hi,
I am trying to feed in a dataset with about 8000 instances (8391x8), but it gets an exception in LogisticRegression.train function computing d_y = self.y - p_y_given_x;
the error is
ValueError: operands could not be broadcast together with shapes (8391,2) (8,2)
I suppose using CDBN/CRBM classes we can do a prediction like regression but I don't know why the p_y_given_x size is not matching self.y which suppose to do.
Also I am using python.

thanks in advance
