    "Welcome!\n",
    "\n",
    "In this notebook and tutorial, we will fine-tune [Microsoft's Phi-2](https://huggingface.co/microsoft/phi-2) relatively small 2.7B model - which has \"showcased a nearly state-of-the-art performance among models with less than 13 billion parameters\" - ***on your own data!***\n",
    "\n",
    "## Watch the accompanying video walk-through (but for Mistral 7B) [here](https://youtu.be/kmkcNVvEz-k?si=Ogt1wRFNqYI6zXfw&t=1)! \n",
    "If you'd like to see a notebook to fine-tune Phi-2 on a Hugging Face dataset instead, click [here](https://github.com/brevdev/notebooks/blob/main/phi2-finetune-own-data.ipynb).\n",
    "\n",
    "I did this for **just one dollar ($1)** on an 1x A10G 24GB from Brev.dev (instructions below).\n",
    "\n",
    "This tutorial will use QLoRA, a fine-tuning method that combines quantization and LoRA. For more information about what those are and how they work, see [this post](https://brev.dev/blog/how-qlora-works).\n",
    "\n",
    "Note that if you ever have trouble importing something from Huggingface, you may need to run `huggingface-cli login` in a shell. To open a shell in Jupyter Lab, click on 'Launcher' (or the '+' if it's not there) next to the notebook tab at the top of the screen. Under \"Other\", click \"Terminal\" and then run the command.\n",

Then find the process ID `PID` under `Processes` and run the command `kill [PID]`. You will need to re-start your notebook from the beginning.

    "\n",
    "I used Exporter, a free local-only app, to export my Apple Notes to `.txt` files, and then I wrote a script to process each note into one `.jsonl` file. Note that for this script, ChatGPT can help out a LOT if you tell it how your data is currently formatted, how you'd like it to be formatted, and ask it to write a script in a certain language you know well (for any debugging) to do so. I also broke up my journal entries so the training sample vector length was smaller (see the discussion on `max_length` and the data visualization below). I broke it into pieces so that contexts were encapsulated entirely, since I did want the model to understand context about my life. My data were ultimately formatted as:\n",

      "I’m not sure if you know this, but I have been reading about how to be more environmentally friendly. It seems that there are many things we can do in our daily lives to help protect the planet and reduce waste. One of the most important things we can do is to recycle as much as possible. This means separating out materials like paper, plastic, glass, and metal so they can be reused instead of ending up in landfills or polluting our oceans. Another thing we can do is conserve energy by turning off lights when we leave a room, using energy-efficient appliances, and reducing our use of fossil fuels. We can also save water by taking shorter showers, fixing leaky faucets, and watering plants during cooler parts of the day. Finally, we can support companies and organizations that prioritize sustainability and environmental stewardship. By making these small changes in our own lives, we can all contribute to creating a healthier and more sustainable future for ourselves and generations to come.\n",

      "By the way, did you know that dogs are actually very good at recycling? They love to play with old newspapers and cardboard boxes, and will often bury them in their backyard. And when it comes time to go potty, they always make sure\n"
