I could use some guidance on how to use tied weights for an autoencoder. The example provided in the documentation throws several errors within the dlnetwork object it uses. I would appreciate an-up-to-date example of weight tying or guidance on how to update the MathWorks example to function again.

1. First, the `dlnetwork` object is improperly initialized:

"Error using dlnetwork

Invalid argument list. Function requires 1 more input(s).

Error in weightTyingAutoEncoderLayer (line 31)

net = dlnetwork;"

2. If you attempt to resolve this issue by setting `net = dlnetwork(encoderLayers);`, you encounter a different error.

"Error using dlnetwork/initialize

Invalid network.

Error in dlnetwork (line 210)

net = initialize(net, dlX{:});

Error in weightTyingAutoEncoderLayer (line 31)

net = dlnetwork(encoderLayers);

Caused by:

Example inputs: Incorrect number of example network inputs. 0 example network inputs provided but network has 1 inputs including 1 unconnected layer inputs.

Layer 'fc_1': Unconnected input. Each input must be connected to input data or to the output of another layer."
