Null Reference from TextureConverter

Unity Engine

I’m new to Sentis, so thanks in advance for bearing with me.
I’m trying to get started with converting Textures to Tensors and vice versa, but I’m running into a null-ref exception every time I try to call a TextureConverter operation.

NullReferenceException: Object reference not set to an instance of an object

Apologies if this is a duplicate but I’d really appreciate any help! Thanks so much.

BTW using Unity 2022.3.27f1 and Sentis 1.2

Are you running this on WebGL?

Hi! Was this resolved? I am running into the same error. I am creating a Unity project for UWP

GPU compute won’t work in WeblGL.
Either use GPUPixel or switch to WebGPU

Check If the “Packages/com.unity.sentis/Runtime/Core/Resources/Sentis/TextureConversion” exists. If not, remove the Sentis and download the Sentis using the git URL.
