Try with NeMo AutoModel

1. Install (full instructions):

$pip install nemo-automodel

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/hunyuan_t2v_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. Run the recipe:

$torchrun --nproc-per-node=8 \
>  examples/diffusion/finetune/finetune.py \
>  -c examples/diffusion/finetune/hunyuan_t2v_flow.yaml
