Hello again, Sorry I accidentally got it posted, while I was still continuing to write. Runing the partial derivative block seems to raise the error
theano.gof.fg.MissingInputError: ("An input of the graph, used to compute Elemwise{Cast{float64}}(mask_1), was not provided and not given a value.Use the Theano flag exception_verbosity='high',for more information on this error.", mask_1) Starngely, It works when the network a single layer. Upon increasing the number of layers, the error shows up. I am using Theano (0.8.2). Any help would be greatly appreciated. best regards, Satyan -- --- You received this message because you are subscribed to the Google Groups "theano-users" group.
