[Linux] CUDA error upon trying to generate

[ThorinWolf]

OS: Arch Linux rolling
GPU: GTX 1660 SUPER
Driver: nvidia-520.56.06
CUDA: cuda-tools installed

Whenever I go to generate, it crashes on a CUDA error, as shown below. I have all dependencies listed plus a fair few others since it also pointed out I didn't have them. I'm using a local clone of v1.4 of the diffusion model renamed to v1.5 because the program wants to only accept a v1.5 folder despite it not being out for the public (as far as I can tell) and the HTTPX request fails when I go for the access key.

See terminal output below (the backslashes in the last line are to be ignored, interfered with code block):

Instead of renaming your local files, try changing this line:

UnstableFusion/diffusionserver.py

Line 34 in 91d40dd

"runwayml/stable-diffusion-v1-5",

to this:
"CompVis/stable-diffusion-v1-4", and see if it helps.

[ThorinWolf]

Done, but no effect. Exact same error. And Torch reserving memory but not clearing it properly with each crash means I get out of memory errors if I try to do it for a second time without restarting.

[ahrm]

I assume it is a memory error? Maybe try enabling attention slicing and see if it helps:
65f95a6

[ThorinWolf]

No change, though it was faster to get to starting the generation. Monitoring CPU, memory, GPU & GPU memory via both htop & nvtop. No topping out on either of them, so I presume is not a memory issue.

What is your cuda version?

[ThorinWolf]

NVCC:

$ nvcc --version
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2022 NVIDIA Corporation
Built on Wed_Sep_21_10:33:58_PDT_2022
Cuda compilation tools, release 11.8, V11.8.89
Build cuda_11.8.r11.8/compiler.31833905_0

[ahrm]

Pytorch doesn't support cuda 11.8, the maximum supported version is 11.6.

[ThorinWolf]

Downgraded to:

$ nvcc --version
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2021 NVIDIA Corporation
Built on Fri_Dec_17_18:16:03_PST_2021
Cuda compilation tools, release 11.6, V11.6.55
Build cuda_11.6.r11.6/compiler.30794723_0

Same error occurs. Can try and downgrade further if required, but it is 11.6.
