Error messages

Here is the list of possible error messages and their brief description.

not enough memory:

a dynamic memory allocation failed.

can't load file:

SNNS network-file wasn't found.

can't open file:

same as can't load or disk full.

wrong parameters:

wrong kind or number of parameters.

net contains illegal cycles:

there are several possibilities:

• a connection from a unit which is not a SPECIAL HIDDEN unit to itself.
• two layers are connected to each other when not exactly one of them is SPECIAL HIDDEN.
• cycles over more than two layers which don't match the architecture of Jordan networks.

BPTT-networks have no restrictions concerning links.

can't find the function actfunc:

the activation function actfunc is not supported.

net is not a CounterPropagation network:

Counterpropagation-networks need a
special architecture: one input, one output and one hidden layer which are fully connected.

net is not a Time Delay Neural Network:

The SNNS TDNNs have a very special architecture. They should be generated by the BIGNET-tool. In other cases there is no guaranty for successful compilation.

not supported network type:

There are several network types which can't be compiled with the SNNS2C. The SNNS2C-tool will be maintained and so new network types will be implemented.

unspecified Error:

should not occur, it's only a feature for user defined updates.

unknown error code : number:

must not occur, please report to the SNNS-Team.
