Try with NeMo AutoModel

1. Install (full instructions):

pip install "nemo-automodel[diffusion,diffusion-media]"

2. Clone the repo to get the example recipes:

git clone https://github.com/NVIDIA-NeMo/Automodel.git
cd Automodel

3. Run the recipe from inside the repo:

torchrun --nproc-per-node=8 \
  examples/diffusion/finetune/finetune.py \
  -c examples/diffusion/finetune/qwen_image_t2i_flow.yaml

1. Pull the container and mount a checkpoint directory:

docker run --gpus all -it --rm \
  --shm-size=8g \
  -v $(pwd)/checkpoints:/opt/Automodel/checkpoints \
  nvcr.io/nvidia/nemo-automodel:26.06.00

2. Navigate to the AutoModel directory (where the recipes are):

cd /opt/Automodel

3. Install media dependencies (not installed in the container by default):

uv pip install ".[diffusion-media]"

4. Run the recipe:

torchrun --nproc-per-node=8 \
  examples/diffusion/finetune/finetune.py \
  -c examples/diffusion/finetune/qwen_image_t2i_flow.yaml
