…t#27413) ### Details: - *Inherit signature from forward while patching* ### Tickets: - *ticket-id* --------- Signed-off-by: Maxim Vafin <[email protected]>
### Details: - *`no_jit_trace` was using extra memory to get and store trace state, which contained all graph that was produced before, that increase memory consumption of tracing. For example for FLUX model it used about 20Gb of extra memory* - *Saving `args` on meta device didn't work without `no_jit_trace`. To workaround this issue we now pass args directly to forward without saving them in `Trampoline`. This allows better flow for arguments and reduce memory used to save those args. However this changes the behavior of `evaluate` of `ModuleExtension`, because now it uses the args that were passed to `convert` and not the original args.* optimum-cli for FLUX with `torch_dtype=torch.bfloat16` before change:  optimum-cli for FLUX with `torch_dtype=torch.bfloat16` after change:  Note: optimum doesn't yet support `torch_dtype=torch.bfloat16` for FLUX. ### Tickets: - *CVS-151254* --------- Signed-off-by: Maxim Vafin <[email protected]>
