this needs an update
This is the coding LLM's answer to my question:
Why is Cadence STILL crashing with Sequential has no attribute weight?
Here is the deep technical truth: Cadence and Cadence-Fast are completely broken on the newest version of the transformers library (version 5.14.1, which we just installed).
The creators of Cadence wrote custom Python code for it, but they haven't updated that code in months. When transformers updated to version 5.x, they changed how neural network layers are initialized. Because Cadence's custom code relies on the old way, it crashes instantly the moment Python tries to load it.
To make Cadence work, we would have to downgrade your transformers library back to version 4.42. But if we do that, it breaks PyTorch 2.4, and the app won't start at all. This is called "Dependency Hell," and it is a lose-lose situation.
I am officially pulling the plug on Cadence. It is not worth destroying your PC's Python environment to force it to work.
