## Conda Setup:

```python
conda install -c conda-forge mpi4py
conda install pytorch torchvision torchaudio cudatoolkit=11.3 -c pytorch
pip install -e improved-diffusion/
pip install -e transformers/
pip install spacy==3.2.4
pip install datasets==1.8.0
pip install huggingface_hub==0.4.0
pip install wandb
```

---

## Train Diffusion-LM:

`cd improved-diffusion;`

`python scripts/run_train.py --diff_steps 2000 --model_arch transformer --lr 0.0001 --lr_anneal_steps 400000 --save_interval 50000 --seed 101 --noise_schedule sqrt --in_channel 128 --modality roc-free --submit no --padding_mode pad --app "--predict_xstart True --training_mode e2e --vocab_size 11043 --roc_train datasets/ROCstory " --notes xstart_e2e --bsz 64`

---

## Controllable Text Generation

`python scripts/infill_free.py --model_path 'diffusion_models/diff_roc-free_pad_rand128_transformer_lr0.0001_0.0_2000_sqrt_Lsimple_h128_s2_d0.1_sd101_xstart_e2e/model{model epochs}.pt' --eval_task_ 'free_emotion' --use_ddim True --notes "tree_adagrad" --eta 1. --verbose pipe`
