How can I convert pre-trained model to coreml to use it on ios application?

[sarojraut]

I am using coremltools to do so.

import coremltools as ct
 import torch
 import torch.nn as nn

 model = torch.load('/Users/sarojraut/Downloads/side.pth',map_location=torch.device('cpu'))
 example_input = torch.rand(1, 3, 224, 224) 

 traced_model = torch.jit.trace(model, example_input)

But I get error

Traceback (most recent call last):
 File "<pyshell#34>", line 1, in <module>
 traced_model = torch.jit.trace(model, dummy_input)
 File "/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-   packages/torch/jit/_trace.py", line 846, in trace
