CLIP_IQA: Need optimized model for mobile

[GaneshPulivendula2024]

In the clip.py file of piq\feature_extractors, I am trying to save the model using torch jit script in load() function, as I need clip_iqa optimized model for android mobile.

traced_script_module = torch.jit.script(model) traced_script_module.save(os.path.join(os.path.expanduser("~/.cache/clip"), "clip_iqa_trace.pt")) traced_script_module_optimized = optimize_for_mobile(traced_script_module) traced_script_module_optimized._save_for_lite_interpreter(os.path.join(os.path.expanduser("~/.cache/clip"), "clip_iqa_mobile.ptl"))

However I am getting the below error. Please suggest how can I save the optimized clip_iqa model.
