 ### Advanced Pip Installation
-`⚠️Do **NOT** use this if you have Conda.` Pip is a bit more complex since there are dependency issues. The pip command is different for `torch 2.2,2.3,2.4,2.5` and CUDA versions.

-For other torch versions, we support `torch211`, `torch212`, `torch220`, `torch230`, `torch240` and for CUDA versions, we support `cu118` and `cu121` and `cu124`. For Ampere devices (A100, H100, RTX3090) and above, use `cu118-ampere` or `cu121-ampere` or `cu124-ampere`.

 For example, if you have `torch 2.4` and `CUDA 12.1`, use:
 ```bash
 pip install --upgrade pip
 pip install "unsloth[cu121-torch240] @ git+https://github.com/unslothai/unsloth.git"
