1. Type into Terminal: Now you can finally run ComfyUI by following command.

   • Run on Linux:

     python main.py

   • Run on macOS:

     python main.py --force-fp16

2. For your convenience, you can create a bash script, such as a run.sh file, to avoid manually activating the virtual environment and running ComfyUI from the terminal each time you want to use it.

   #!/bin/bash source venv/bin/activate if [[ "$OSTYPE" == "linux-gnu"* ]]; then python main.py elif [[ "$OSTYPE" == "darwin"* ]]; then python main.py --force-fp16 fi

3. After creating a script file, you can run it by command:

   bash run.sh

See how to Work with Terminal.

1. Open Command Prompt: Now you can finally run ComfyUI by following command.

   • Run on AMD:

     python main.py --directml

   • Run on NVIDIA:

     python main.py

2. For your convenience, you can create a script, such as a run.bat file, to avoid manually activating the virtual environment and running ComfyUI from the terminal each time you want to use it.
