Bare Miniconda One‑Click Installer

This installer creates a clean, isolated Miniconda environment that’s preloaded with the essentials:

✅ Torch (PyTorch 2.8.0 + CUDA 12.8)
✅ Flash Attention
✅ Sage Attention
✅ Triton (Windows build)

The idea here is flexibility. This installer is great if:

• You want a ready‑to‑use ML environment for your own projects.

• You need the latest attention optimizations (Flash + Sage).

• You want all your dependencies automatically isolated, so they don’t interfere with other projects.

👉 What you get: a clean foundation environment you can drop into any project, with all the heavy lifting handled.

💻 System & Software Requirements

To run either installer and projects successfully, make sure your Windows device meets the following:

Hardware:

• GPU: NVIDIA GPU with at least 4GB VRAM recommended (example: RTX 3060 or higher) for best performance. Your GPU must be CUDA-capable to leverage Flash and Sage Attention optimizations.

• RAM: Minimum 8GB system memory, ideally 16GB or more for complex tasks.

• Storage: At least 15-40GB free disk space, preferably on an SSD for faster loading and operation.

Software:

• Operating System: Windows 10 or later.

• Git: Required for cloning repositories; installed automatically by the scripts if missing.

• NVIDIA CUDA Toolkit: For NVIDIA GPU users, install the NVIDIA CUDA Toolkit and the latest compatible NVIDIA drivers to enable GPU acceleration. The toolkit provides essential development libraries and drivers needed for Flash and Sage Attention to work correctly.

💡 Why This Matters

Instead of spending hours troubleshooting installs, you can just focus on building and creating.

⚡ These are Windows‑only right now. Just download, run the .bat, and you’re good to go.
