Give ModuleNotFoundError for few packages

[YukiRed]

Package like the following is not install

• diffusers
• ultralytics
• segment_anything

Turns out it is because launch is not available and unable to pip install launch.
Have to change to using subprocess

import subprocess

required_packages = {
    "accelerate": "accelerate",
    "diffusers": "diffusers",
    "huggingface_hub": "huggingface-hub",
    "numpy": "numpy",
    "cv2": "opencv-python",
    "PIL": "Pillow",
    "segment_anything": "segment-anything",
    "transformers": "transformers",
    "ultralytics": "ultralytics",
    "tqdm": "tqdm",
    "packaging": "packaging",
    "loguru": "loguru",
    "rich": "rich",
    "pydantic": "pydantic",
    "timm": "timm",
}

for package in required_packages:
    try:
        __import__(package)
        print(f"{package} is already installed.")
    except ImportError:
        try:
            subprocess.run(["pip", "install", required_packages[package]], check=True)
            print(f"Successfully installed {required_packages[package]}.")
        except subprocess.CalledProcessError:
            print(f"Can't install {required_packages[package]}. Please follow the readme to install manually.")

Although I couldn't reproduce the issue, I have modified the install.py file to allow installation even when the launch package is not found. Please update and try again.
