How can I run the project without using Apex?

[JamesTensor]

The Git homepage mentions that the project can be run without using Apex.

#set enable_layernorm_kernel=False in config to avoid using Apex

What is the specific command for this?

I added --enable_layernorm_kernel=False after the inference command, but it reported an error that the parameter was unrecognized.
I also modified the 'enable_layernorm_kernel': False under the script opensora/configs/opensora/inference/16x256x256.py, but it still doesn't work.

Hi, you need to navigate to the file "configs/opensora-v1-1/train/stage2.py" and make the following modifications:
model = dict(
type="STDiT2-XL/2",
from_pretrained=None,
input_sq_size=512, # Note: the pretrained model is trained on 512x512
qk_norm=True,
enable_flashattn=True,
enable_layernorm_kernel=False,
)

That's correct. You need to manually modify the config file.
