By “scripted model” I meant a model, which was scripted via torch.jit.script, while a traced model would be created via torch.jit.trace.
As said before, tracing your model might work, if you don’t have any data-dependent code paths. I.e. if your model is static and tracing it works fine, you should be able to use amp. However, this is not tested properly and I would see it as an experimental workflow. Scripting a model with amp is not implemented yet.
