Troubleshooting#

Unknown or missing shape

Some custom/lazy layers do not expose a usable output shape at visualization time. Build/call the model as appropriate or provide labels that do not require unavailable shape metadata.

Graph edges missing after framework upgrade

Verify Keras/TensorFlow compatibility and layer-node traversal rather than changing graph layout parameters first.

Text/font errors

Confirm the selected font exists in the documentation/runtime environment. Avoid embedding machine-specific font paths in reusable examples.

Image too large

Reduce scale, ignore non-essential layers, use a graph view, or render a selected sub-model.
