NNModel can not Attach to ModelAssets

[amenonegames]

Hi , I trying to StyleTransfer_Barracuba.
Having successfully used the included model, then I attempted to try another.

But NNModel I prepareed* can not Attach to StyleTransfer_Barracuba.> Options > ModelAssets.
On the contrary, I found that the included mosaic and intel-mesh-shader models were not attached by dragging and dropping!
Can StyleTransfer_Barracuba only be used with the same settings as when it was added?

I apologize if my question is not appropriate here.
Thank you for your confirmation.

*I prepareed the models from this URL

**I would like to use HDRP in the end, but the results were the same for both BuiltIn and HDRP.

Operating environment
Unity 2021.3.10f1
HDRP Version 12.1.7
In HDRP Template Scene
