+After you have completed the model conversion according to the above process, you can use the following command to start a simple Web UI:
+
+```bash
+python -m python_coreml_stable_diffusion.web -i <output-mlpackages-directory> --compute-unit ALL
+```
+
+After the command is executed, we will get a log similar to the following:
+
+```bash
