out of memory when downloading models locally.

[luluxxxxx]

hello. i'm trying to use the models locally to avoid downloading them at each run.
using
DALLE_MODEL = "dalle-mini/dalle-mini/mega-1-fp16:latest"
DALLE_COMMIT_ID = None
works fine and gives me a result but it will download the models at each run.

i've downloaded the models locally using
git lfs install
git clone https://huggingface.co/dalle-mini/dalle-mega
git lfs install
git clone https://huggingface.co/dalle-mini/vqgan_imagenet_f16_16384
under a /model directory
and now use
DALLE_MODEL = "./models/mega/dalle-mega"
DALLE_COMMIT_ID = None
VQGAN_REPO= "./models/vqgan/vqgan_imagenet_f16_16384"
VQGAN_COMMIT_ID= None

but now it gives me a memory error :

jaxlib.xla_extension.XlaRuntimeError: RESOURCE_EXHAUSTED: Out of memory while trying to allocate 402653184 bytes.

i have a Nvidia GTX 1080 with 8192 MB of memory.
but i wonder why it works when downloading the models. is it using a smaller part of it ?
sorry if all this are dumb questions.

thanks in advance
