'peft' is not defined in patching_utils.py

There is an issue right now in patch_compiling_bitsandbytes() function that won't let us properly load models for Lora training, this is the working solution that I tested on my fork and was able to start the training:

# Also disable compiling on bitsandbytes
def patch_compiling_bitsandbytes():
    # All Unsloth Zoo code licensed under LGPLv3
    os.environ["UNSLOTH_PATCHED"] = "1"
    import bitsandbytes
    if Version(bitsandbytes.__version__) >= Version("0.46.0"):
        if os.environ.get("UNSLOTH_ENABLE_LOGGING", "0") == "1":
            print("Unsloth: Bitsandbytes >= 0.46.0 supports torch.compile - enabling.")
    else:
        # Disable dynamo on Linear4bit, Linear8bit and other future modules
        if os.environ.get("UNSLOTH_ENABLE_LOGGING", "0") == "1":
            print("Unsloth: Bitsandbytes < 0.46.0 does not support torch.compile - disabling.")
        
        # FIX: Create a namespace dict to store imports
        namespace = {}
        
        for x in ["bitsandbytes.nn.modules", "peft.tuners.lora.bnb",]:
            try:
                # Import the module into namespace
                exec(f"import {x}", namespace)
                
                # Get the module from namespace
                module = eval(x, namespace)
                layers = dir(module)
                
                for fx in layers:
                    try:
                        layer = getattr(module, fx)
                    except:
                        continue
                    if not hasattr(layer, "forward"):
                        continue
                    if hasattr(layer.forward, "__wrapped__"):
                        continue
                    
                    # Disable dynamo on the forward method
                    layer.forward = torch._disable_dynamo(layer.forward)
            except ImportError:
                # Raise a helpful message if peft is not installed
                if "peft" in x:
                    raise ImportError("Unsloth: Please install peft via `pip install peft`")
                continue
    return
pass
