Description

1. Purpose: creating an Android demo, that needs tflite (but all new exciting things are in PyTorch)
2. What:

...

UnboundLocalError: cannot access local variable 'new_size' where it is not associated with a value

3. How: I've adjusted the onnx several times to avoid issues with input names, Tile op and Cast op to float64 (edited in onnx-modifier). But this operator (the last one!) is necessary and it appears the issue is with an uninitialized variable in the Resize op conversion itself. Looking at the code it appears new_size is always assigned unless sizes is None... but then it gets a bit complicated.
I've also tried other various other tools. This looks the most promising, but I can try others again to get past their errors.
I've also been working with both Windows and WSL2, different python / module versions to check dependencies etc. (finding magic numpy version that works for everything etc)
4. Why: My demo needs this network, however I can get it to tflite
5. Resources should just need the onnx for this.
