I have verified several times that there is indeed this problem. version 0.3.0 is fine

[OlegPonomaryov]

Could you please check your encoder's *.mlpackage and confirm that it actually has an input named z like in this example?

[jiangdi0924]

@OlegPonomaryov My model file was created earlier. I'm wondering if that could be the reason why I haven't seen the results as shown in the provided image. I would like to know if recompiling the model is the only way to make it work. Thank you very much for your response.

[OlegPonomaryov]

Definitely the issue is with the encoder's version, however I'm not that familiar with the problem and don't know if incompatibility goes beyond the input naming. Looks like #177 contains conversion instructions, so I'd start from there.

Can either of you please tell me what app you are using in the screen caps above to display the model information? TIA.

[OlegPonomaryov]

@jrittvo You just need to open *.mlpackage file in Xcode.
