+# **SMOLLM CoT 360M ON CUSTOM SYNTHETIC DATA**
+
+SmolLM2 is a family of compact language models available in three size: 135M, 360M, and 1.7B parameters. They are capable of solving a wide range of tasks while being lightweight enough to run on-device. Fine-tuning a language model like SmolLM involves several steps, from setting up the environment to training the model and saving the results. Below is a detailed step-by-step guide based on the provided notebook file 
+
+---
+
+# How to use `Transformers`
+```bash
+pip install transformers
+```
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+checkpoint = "prithivMLmods/SmolLM2-CoT-360M"
+
+device = "cuda" # for GPU usage or "cpu" for CPU usage
+tokenizer = AutoTokenizer.from_pretrained(checkpoint)
+# for multiple GPUs install accelerate and do `model = AutoModelForCausalLM.from_pretrained(checkpoint, device_map="auto")`
+model = AutoModelForCausalLM.from_pretrained(checkpoint).to(device)
+
+messages = [{"role": "user", "content": "What is the capital of France."}]
+input_text=tokenizer.apply_chat_template(messages, tokenize=False)
+inputs = tokenizer.encode(input_text, return_tensors="pt").to(device)
+outputs = model.generate(inputs, max_new_tokens=50, temperature=0.2, top_p=0.9, do_sample=True)
+print(tokenizer.decode(outputs[0]))
+```
+
+### **Step 1: Setting Up the Environment**
+Before diving into fine-tuning, you need to set up your environment with the necessary libraries and tools.
+
+1. **Install Required Libraries**:
+   - Install the necessary Python libraries using `pip`. These include `transformers`, `datasets`, `trl`, `torch`, `accelerate`, `bitsandbytes`, and `wandb`.
+   - These libraries are essential for working with Hugging Face models, datasets, and training loops.
+
+   ```python
+   !pip install transformers datasets trl torch accelerate bitsandbytes wandb
+   ```
+
+2. **Import Necessary Modules**:
+   - Import the required modules from the installed libraries. These include `AutoModelForCausalLM`, `AutoTokenizer`, `TrainingArguments`, `pipeline`, `load_dataset`, and `SFTTrainer`.
+
+   ```python
+   from transformers import AutoModelForCausalLM, AutoTokenizer, TrainingArguments, pipeline
+   from datasets import load_dataset
+   from trl import SFTConfig, SFTTrainer, setup_chat_format
+   import torch
+   import os
+   ```
+
+3. **Detect Device (GPU, MPS, or CPU)**:
+   - Detect the available hardware (GPU, MPS, or CPU) to ensure the model runs on the most efficient device.
+
+   ```python
+   device = (
+       "cuda"
+       if torch.cuda.is_available()
+       else "mps" if torch.backends.mps.is_available() else "cpu"
+   )
+   ```
+---
+
+### **Step 2: Load the Pre-trained Model and Tokenizer**
+Next, load the pre-trained SmolLM model and its corresponding tokenizer.
+
+1. **Load the Model and Tokenizer**:
+   - Use `AutoModelForCausalLM` and `AutoTokenizer` to load the SmolLM model and tokenizer from Hugging Face.
+
+   ```python
+   model_name = "HuggingFaceTB/SmolLM2-360M"
+   model = AutoModelForCausalLM.from_pretrained(pretrained_model_name_or_path=model_name)
+   tokenizer = AutoTokenizer.from_pretrained(pretrained_model_name_or_path=model_name)
+   ```
+
+2. **Set Up Chat Format**:
+   - Use the `setup_chat_format` function to prepare the model and tokenizer for chat-based tasks.
+
+   ```python
+   model, tokenizer = setup_chat_format(model=model, tokenizer=tokenizer)
+   ```
+
+3. **Test the Base Model**:
+   - Test the base model with a simple prompt to ensure it’s working correctly.
+
+   ```python
+   prompt = "Explain AGI ?"
+   pipe = pipeline("text-generation", model=model, tokenizer=tokenizer, device=0 if device == "cuda" else -1)
+   print(pipe(prompt, max_new_tokens=200))
+   ```
+4. **If: Encountering**:
+   - Chat template is already added to the tokenizer, indicates that the tokenizer already has a predefined chat template, which prevents the setup_chat_format() from modifying it again.
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline
+
+model_name = "HuggingFaceTB/SmolLM2-1.7B-Instruct"
+model = AutoModelForCausalLM.from_pretrained(pretrained_model_name_or_path=model_name)
+tokenizer = AutoTokenizer.from_pretrained(pretrained_model_name_or_path=model_name)
+
+tokenizer.chat_template = None
+
+from trl.models.utils import setup_chat_format
+model, tokenizer = setup_chat_format(model=model, tokenizer=tokenizer)
+
+prompt = "Explain AGI?"
+pipe = pipeline("text-generation", model=model, tokenizer=tokenizer, device=0)
+print(pipe(prompt, max_new_tokens=200))
+```
+*📍 Else Skip the Part [ Step 4 ] !*
+
+---
+
+### **Step 3: Load and Prepare the Dataset**
+Fine-tuning requires a dataset. In this case, we’re using a custom dataset called `Deepthink-Reasoning`.
+
+![image/png](https://cdn-uploads.huggingface.co/production/uploads/65bb837dbfb878f46c77de4c/JIwUAT-NpqpN18zUdo6uW.png)
+
+1. **Load the Dataset**:
+   - Use the `load_dataset` function to load the dataset from Hugging Face.
+
+   ```python
+   ds = load_dataset("prithivMLmods/Deepthink-Reasoning")
+   ```
+
+2. **Tokenize the Dataset**:
+   - Define a tokenization function that processes the dataset in batches. This function applies the chat template to each prompt-response pair and tokenizes the text.
+
+   ```python
+   def tokenize_function(examples):
+       prompts = [p.strip() for p in examples["prompt"]]
+       responses = [r.strip() for r in examples["response"]]
+       texts = [
+           tokenizer.apply_chat_template(
+               [{"role": "user", "content": p}, {"role": "assistant", "content": r}],
+               tokenize=False
+           )
+           for p, r in zip(prompts, responses)
+       ]
+       return tokenizer(texts, truncation=True, padding="max_length", max_length=512)
+   ```
+
+3. **Apply Tokenization**:
+   - Apply the tokenization function to the dataset.
+
+   ```python
+   ds = ds.map(tokenize_function, batched=True)
+   ```
+
+---
+
+### **Step 4: Configure Training Arguments**
+Set up the training arguments to control the fine-tuning process.
+
+1. **Define Training Arguments**:
+   - Use `TrainingArguments` to specify parameters like batch size, learning rate, number of steps, and optimization settings.
+
+   ```python
+   use_bf16 = torch.cuda.is_bf16_supported()
+   training_args = TrainingArguments(
+       per_device_train_batch_size=2,
+       gradient_accumulation_steps=4,
+       warmup_steps=5,
+       max_steps=60,
+       learning_rate=2e-4,
+       fp16=not use_bf16,
+       bf16=use_bf16,
+       logging_steps=1,
+       optim="adamw_8bit",
+       weight_decay=0.01,
+       lr_scheduler_type="linear",
+       seed=3407,
+       output_dir="outputs",
+       report_to="wandb",
+   )
+   ```
+
+---
+
+### **Step 5: Initialize the Trainer**
+Initialize the `SFTTrainer` with the model, tokenizer, dataset, and training arguments.
+
+```python
+trainer = SFTTrainer(
+    model=model,
+    processing_class=tokenizer,
+    train_dataset=ds["train"],
+    args=training_args,
+)
+```
+
+---
+
+### **Step 6: Start Training**
+Begin the fine-tuning process by calling the `train` method on the trainer.
+
+```python
+trainer.train()
+```
+
+---
+
+### **Step 7: Save the Fine-Tuned Model**
+After training, save the fine-tuned model and tokenizer to a local directory.
+
+1. **Save Model and Tokenizer**:
+   - Use the `save_pretrained` method to save the model and tokenizer.
+
+   ```python
+   save_directory = "/content/my_model"
+   model.save_pretrained(save_directory)
+   tokenizer.save_pretrained(save_directory)
+   ```
+
+2. **Zip and Download the Model**:
+   - Zip the saved directory and download it for future use.
+
+   ```python
+   import shutil
+   shutil.make_archive(save_directory, 'zip', save_directory)
+
+   from google.colab import files
+   files.download(f"{save_directory}.zip")
+   ```
