RuntimeError: Encountering a dict at the output of the tracer

[wolfbeast]

Describe the bug

Following the instructions to install onnx on Windows, I'm running into a python runtime error when running save_onnx.py
The script successfully fetches a bunch of models, then errors out with a runtime error (see log).
I initially ran into issue #14 but following the diffusers update hint in the last post there I got past that, however ran into this issue with no hint how to solve that.

Reproduction

1. Follow the instructions linked above, use Python 3.11 and the Python 3.11 onnx package. proceed to the last step of "Generating a onnx-based stable-diffusion v1.4 model"
2. Run pip install -U diffusers to work around getattr() attribute name must be a string #14
3. Run python ./save_onnx.py

RuntimeError: Encountering a dict at the output of the tracer might cause the trace to be incorrect, this is only valid if the container structure does not change based on the module's inputs. Consider using a constant container instead (e.g. for `list`, use a `tuple` instead. for `dict`, use a `NamedTuple` instead). If you absolutely need this and know the side effects, pass strict=False to trace() to allow this behavior.

System Info

Python 3.11
updated diffusers to 0.23.1 after running into #14

Nuked the python env, installed 3.10; same error is thrown.
older python installers have been yanked and aren't available so I'm at a dead end here. Any help appreciated solving this problem.
