Installation

To get started, let’s walk through the installation steps. This is akin to setting up a new game console—follow the steps carefully to get everything working smoothly.

• Clone the repository:

git clone https://github.com/IceClear/StableSR.git

• Navigate to the StableSR directory:

cd StableSR

• Create a conda environment and activate it:

conda env create --file environment.yaml
conda activate stablesr

• Finally, install any required packages listed in environment.yaml.

Once these steps are completed, your environment will be ready for training or testing!

Running Examples

After setting up your environment, it’s time to run some examples. Think of this like choosing your character in a video game—select the right setup to achieve amazing results.

Training the Model

Choose whether to fine-tune or test with pretrained models:

• To train, run the following command (don’t forget to replace GPU_ID with your GPU’s ID):

python main.py --train --base configs/stableSRNewv2-finetune_text_T_512.yaml --gpus GPU_ID --name NAME --scale_lr False

• If you’re testing the model:

python scripts/sr_val_ddpm_text_T_vqganfin_old.py --config configs/stableSRNewv2-finetune_text_T_512.yaml --ckpt CKPT_PATH --init-img INPUT_PATH --outdir OUT_DIR --ddpm_steps 200 --dec_w 0.5 --colorfix_type adain

Troubleshooting

Even the best adventures can have hiccups. Here are some troubleshooting tips to help you through common problems:

• Issue: Environment errors or package conflicts.
• Solution: Double-check your installed packages. It may help to create a fresh conda environment.
• Issue: Out of memory errors when running scripts.
• Solution: Ensure your GPU is capable of running the model with the set parameters. Reduce batch sizes or resolution for testing.
• Issue: Unexpected output quality.
• Solution: Revisit training configurations and pre-trained model paths. Ensure data quality is high and that the scripts are configured correctly.
