Compiling SD1.5 for Neuron with resolution other than 512x512 fails

🤗Optimum

I’m trying to export SD 1.5 into a portrait mode resolution 512x768 for use with Neuron / Inferentia 2. This is my export command:

optimum-cli export neuron \
    --model jyoung105/stable-diffusion-v1-5 \
    --task stable-diffusion \
    --batch_size 1 --num_images_per_prompt 1 \
    --height 768 --width 512 \
    stable-diffusion-v1-5.neuron

It works in 512x512 but fails with 512x768 with this error in the vae_encoder step:

An error occured when trying to trace vae_encoder with the error message: neuronx-cc failed with 70.
The export is failed and vae_encoder neuron model won't be stored.

Do I need any other parameters or is it a bug that needs fixing? I’m running it on AWS inf2.2xlarge instance.

Somehow I managed to export some SD1.5 checkpoint to 512x768 a couple weeks ago but I’m unable to reproduce it now. Is that a possible regression in optimum-neuron or neuronx-cc?

@Jingya sorry to bother you directly, but you’re always so helpful :blush:

Any idea why compiling the model for any resolution other than 512x512 fails?

I have one Neuron model that I was able to compile for 512x768 a few weeks ago but I no longer have the setup and don’t remember the exact command, and now it always fails.

Is it something that can be fixed? Or am I doing something wrong?

Hi @hgfckwla,

The compilation error should come from AWS Neuron sdk instead of Optimum Neuron. According to AWS folks, the compilation for SD models with unequal height/width should have been supported by the SDK version following the 2.18.2 so 2.19.0 and 2.19.1: enable unequal height and width by yahavb · Pull Request #592 · huggingface/optimum-neuron · GitHub.

Can you still recall the SDK version you used for successful compilation?

I got this when compiling unequal height/width SD’s vae encoder with neuron SDK 2.19.1 on an inf2.8xlarge instance.

I will ask Annapurna folks. And it will be super helpful if you can share the env where you succeeded in compiling it!

Hi @Jingya thanks for confirming the issue. Unfortunately I can’t find my old virtual env with the versions that worked. I think it was on my spot instance that’s now gone :frowning:

No worries, I talked with the Annapurna team, they are working on a fix for the compiler regression. Thanks again for letting us know, I will add a unit test for unequal width/height once the patch is out.
