For example, to increase the number of epochs to train:  
```bash
accelerate launch train_text_to_image_lora.py \
--num_train_epochs=150 \
```  
Many of the basic and important parameters are described in the [Text-to-image](text2image#script-parameters) training guide, so this guide just focuses on the LoRA relevant parameters:  
- `--rank`: the inner dimension of the low-rank matrices to train; a higher rank means more trainable parameters
