Error computing NN outputs

Open martinlexow opened this issue 2 years ago • 2 comments

Tried to run the framework on my iPad (6th gen) and got the following error

[coreml] Error computing NN outputs -1
[coreml] Failure in -executePlan:error:.

Pipeline was initialised successfully however.

Tried using Unet chunks, reduced memory mode, added Extended Virtual Addressing and Increased Memory capabilities without luck.

Any advice would be welcomed!

When I set modelConfig.computeUnits = .cpuOnly it seems to work at first but crashes later due to memory issues.

How can I know on which device I have to use .cpuOnly or .cpuAndGPU?

I've seen a similar error using my own models.

The only way I got around it was to initialize the model once using a singleton. For some reason iOS is fine initializing the model once, but subsequent attempts would result in that error IIRC.

I don't know if that is the case here, but just thought I'd mention it in case it may help.
