Model Card: Math Homework Solver

This is a Large Language Model (LLM) fine-tuned to solve math problems with detailed, step-by-step explanations and accurate answers. The base model used is Llama 3.1 with 8 billion parameters, which has been quantized to 4-bit using QLoRA (Quantized Low-Rank Adaptation) and PEFT (Parameter-Efficient Fine-Tuning) through the Unsloth framework.

Other Homework Solver Models include Math_Homework_Solver_Llama318B and SocialScience_Homework_Solver_Llama318B

Capabilities

The Science Homework Solver model is designed to assist with a broad spectrum of scientifical problems, from basics of gravity to advanced topics like quantum entanglement. It provides clear and detailed explanations, making it an excellent resource for students, educators, and anyone looking to deepen their understanding of scientifical concepts.

By leveraging the Llama 3.1 base model and fine-tuning it using PEFT and QLoRA, this model achieves high-quality performance while maintaining a relatively small computational footprint, making it accessible even on limited hardware.

Getting Started

To start using the Science Homework Solver model, follow these steps:

1. Clone the repo

   git clone https://huggingface.co/justsomerandomdude264/Science_Homework_Solver-Llama3.18B
   

2. Run inference

   1. This method is recommended as its reliable and accurate:

   from unsloth import FastLanguageModel
   import torch
    
   # Define Your Question
   question = "A tank is filled with water to a height of 12.5 cm. The apparent depth of a needle lying at the bottom of the tank is measured by a microscope to be 9.4 cm. What is the refractive index of water? If water is replaced by a liquid of refractive index 1.63 up to the same height, by what distance would the microscope have to be moved to focus on the needle again?" # Example Question, You can change it with one of your own
   # Load the model
   model, tokenizer = FastLanguageModel.from_pretrained(
           model_name = "Science_Homework_Solver_Llama318B/model_adapters", # The dir where the repo is cloned or "\\" for root
           max_seq_length = 2048,
           dtype = None,
           load_in_4bit = True,
       )
   # Set the model in inference model
   FastLanguageModel.for_inference(model)
   # QA template
   qa_template = """Question: {}
   Answer: {}"""
   # Tokenize inputs
   inputs = tokenizer(
   [
       qa_template.format(
           question, # Question
           "", # Answer - left blank for generation
       )
   ], return_tensors = "pt").to("cuda")
   # Stream the answer/output of the model
   from transformers import TextStreamer
   text_streamer = TextStreamer(tokenizer)
   _ = model.generate(**inputs, streamer = text_streamer, max_new_tokens = 512)
   

   1. Another way to run inference is to use the merged adapters (not recommend as it gives inaccurate/different answers):

   from transformers import LlamaForCausalLM, AutoTokenizer
   # Load the model
   model = LlamaForCausalLM.from_pretrained(
       "justsomerandomdude264/Science_Homework_Solver_Llama318B",
       device_map="auto"
   )
   
   # Load the tokenizer
   tokenizer = AutoTokenizer.from_pretrained("justsomerandomdude264/Science_Homework_Solver_Llama318B")
   # Set the inputs up
   qa_template = """Question: {}
   Answer: {}"""
   
   inputs = tokenizer(
   [
       qa_template.format(
           "A tank is filled with water to a height of 12.5 cm. The apparent depth of a needle lying at the bottom of the tank is measured by a microscope to be 9.4 cm. What is the refractive index of water? If water is replaced by a liquid of refractive index 1.63 up to the same height, by what distance would the microscope have to be moved to focus on the needle again?", # instruction
           "", # output - leave this blank for generation!
       )
   ], return_tensors = "pt").to("cuda")
   
   # Do a forward pass
   outputs = model.generate(**inputs, max_new_tokens = 128, use_cache = True)
   raw_output = str(tokenizer.batch_decode(outputs))
   
   # Formtting the string
   # Removing the list brackets and splitting the string by newline characters
   formatted_string = raw_output.strip("[]").replace("<|begin_of_text|>", "").replace("<|eot_id|>", "").strip("''").split("\\n")
   # Print the lines one by one
   for line in formatted_string:
     print(line)
