# 🙋🏻‍♂️Welcome to 🧑🏻‍🚀Tonic's🚀🚰Easy🔴Reddit🔥!


This is every "best reddit_question_best_answers" appended and produced according to the following template :

```json
{"prompt": "This is the first prompt", "completion": "This is the first completion"}
{"prompt": "This is the second prompt", "completion": "This is the second completion"}
```

- 🌟 You can use it in shards or all together !

- 🌟 This dataset is **internally consistent** !



🤔The point is to make it easy to train models with a single correctly formatted dataset of

- 54,367,153 rows

# Original Dataset :

[nreimers/reddit_question_best_answers](https://huggingface.co/datasets/nreimers/reddit_question_best_answers)

# How To Use : 

Combine random shards in random quantities to produce a very high quality conversational training dataset for fine tuning or try combining rows line by line to save memory by running the following code: 

```python

# see selectbyline.py

import os
import random

# Directory containing the shard JSONL files
shard_directory = "/path/to/shard/directory"

# Get a list of all JSONL files in the directory
shard_files = [f for f in os.listdir(shard_directory) if f.endswith('.jsonl')]

# Function to read a random number of lines (between min_lines and max_lines) from a file
def read_random_lines(filename, min_lines, max_lines):
    selected_lines = []
    num_lines = random.randint(min_lines, max_lines)

    with open(filename, 'r') as file:
        lines = list(file)
        if len(lines) <= num_lines:
            return lines
        selected_lines = random.sample(lines, num_lines)

    return selected_lines

# Function to combine shards
def combine_shards(output_filename, num_combinations):
    with open(output_filename, 'w') as output_file:
        for _ in range(num_combinations):
            selected_shard_file = random.choice(shard_files)
            lines = read_random_lines(os.path.join(shard_directory, selected_shard_file), 5000, 10000)
            output_file.writelines(lines)

# Example usage
combine_shards("/path/to/output/combined_shards.jsonl", 10)

```

# Pre-Processing

```python
import json
import os
import gzip
import logging
import re
import random

# Setup basic logging
logging.basicConfig(level=logging.INFO, format="%(asctime)s - %(levelname)s - %(message)s")

    return re.sub(r'[^A-Za-z0-9 ]+', '', s)

def process_file(input_file, output_file):

                except json.JSONDecodeError:
                    logging.error(f"Invalid JSON format in {input_file}: {line}")
                    continue

                # Extract and clean the 'body' and 'answers' fields
                prompt = clean_string(data.get("body", ""))
                completion = clean_string(data.get("answers", ""))

                # For each body found, make a new row and duplicate the prompt for it

                json.dump(item, outfile)
                outfile.write('\n')

        logging.info(f"Processed file: {input_file}")

    except Exception as e:

#### **sharding script** : 

```python

        return []

    shards = [dataset[i:i + shard_size] for i in range(0, len(dataset), shard_size)]
    if len(shards) > num_shards:
        shards[num_shards - 1].extend(shards.pop())
    print(f"Dataset sharded into {num_shards} parts.")
    return shards

def write_shards(shards, output_dir):
    if not os.path.exists(output_dir):

    for i, shard in enumerate(shards):

Disclaimer :

🌟Re-format this dataset before use.

🌟Probably there's a **big problem with the token count** on these long answers 😉

🌟**Good Luck !** 🧑🏻‍🚀🚀
