Hi, I am facing few difficulties in converting the caffe models to CoreML models. I am currently using Macbook Air for my development purposes. When I used the commands provided in the documentation of `coremltools`, I am getting the following error:
```
Traceback (most recent call last): File "coreml.py", line 23, in <module> class_labels='synset_words.txt') File "/ return MLModel(model_path) File "/ self.__proxy__ = _get_proxy_from_spec(model) File "/ return _MLModelProxy.fromSpec(filename) RuntimeError: Got non-zero exit code 72 from xcrun. Output was: xcrun: error: unable to find utility "coremlcompiler", not a developer tool or in PATH
```
It will be really helpful if anyone can tell me what is causing this issue and what is the solution for the same.
