Can the app display the inference time, might be nice to have some stats rendered live as you generate

I think let's do a try catch style here where we try torch.export.export first and then _trace.export. I found _export doesn't work with modelopt recently.

Catch style will make the process slower because it needs to try one and the other, right? My thoughts here is have the user decide whether they have to use allow_complex_guards_as_runtime_asserts, which only _export has. If that is absolute necessary, then we cannot use torch.export.export.
