Docker Setup

I have setup the docker container to run the model evaluation.

Initial Query

Write a self-contained Python program that prints a JSON output of how often each word appears in a text file located in /tmp/file.txt. So if the file contains "This is is is, an example" then the program should print to stdout. {"This": 1, "is": 2, "is,":1, "an":1, "example":1} The program should be run by calling /path/to/python_word_count with no arguments. Make it run in parallel on 4 cores at the same time, each taking 1/4 of the file. Print out 4 differnt json dicts, one per line. I'll do the merging.

Output

Sure! Below is a self-contained Python program that counts the frequency of each word in `/tmp/file.txt` using 4 parallel processes. Each process handles a portion of the file, and the program outputs four separate JSON dictionaries, one per line.

### How It Works: 1. **Reading the File:** - The program reads all lines from `/tmp/file.txt`. It handles potential file reading errors gracefully. 2. **Splitting the Work:** - The `split_lines` function divides the list of lines into 4 roughly equal parts, ensuring that each process gets an approximately equal portion of the file to work on. 3. **Counting Words in Parallel:** - Using Python's `multiprocessing.Pool`, the program spawns 4 parallel processes. - Each process executes the `count_words` function on its assigned chunk of lines, counting the frequency of each word. 4. **Outputting the Results:** - After all processes complete, the main process collects the four dictionaries. - Each dictionary is converted to a JSON string and printed on a separate line to `stdout`. ### Example: Given the content of `/tmp/file.txt` as:
1
This is is is, an example
Running the program will output something like:
1
2
3
4
{"This": 1}
{}
{}
{"is": 2, "is,": 1, "an": 1, "example": 1}
Each JSON object corresponds to one of the four parallel processes. You can merge these dictionaries as needed. ### Running the Program: Save the script to a file, for example, `python_word_count.py`, and ensure it has execute permissions. You can run it using:
1
python /path/to/python_word_count.py
Ensure that the Python interpreter you're using is compatible with the script (Python 3 is recommended).

### Explanation: 1. **Shebang Line**: `#!/usr/bin/env python3` allows the script to be executed directly from the command line. 2. **Imports**: - `json` for JSON serialization. - `os` for file size determination. - `multiprocessing` for parallel processing. 3. **count_words Function**: - Takes a string `text` as input. - Splits the text into words based on whitespace. - Counts the occurrences of each word and returns a dictionary. 4. **split_file Function**: - Divides the file into `num_chunks` parts without splitting words. - Determines split positions by seeking to approximate byte positions and then moving to the end of the current line to avoid breaking words. - Reads each chunk as a string and collects them into a list. 5. **main Function**: - Defines the file path and number of processes. - Splits the file into chunks. - Creates a pool of worker processes. - Maps the `count_words` function to each chunk in parallel. - Prints each resulting JSON dictionary on a separate line. 6. **Execution Guard**: - Ensures that `main` is called only when the script is executed directly. ### Usage: 1. **Make the Script Executable**:
1
2
    chmod +x /path/to/python_word_count
    
2. **Run the Script**:
1
2
    /path/to/python_word_count
    
This script will output four JSON dictionaries, each representing the word counts from a portion of the file `/tmp/file.txt`. Each dictionary will be printed on a separate line, allowing you to merge them as needed. ### Notes: - **Word Splitting**: The `split_file` function ensures that words are not split between chunks by moving to the end of the current line. This assumes that words are separated by newlines or spaces. If your file does not contain newlines, you may need a more sophisticated method to prevent splitting words. - **Performance**: This script reads the file in chunks and processes them in parallel, leveraging multiple CPU cores for efficiency. - **Merging Results**: After running the script, you'll receive four separate JSON dictionaries. You can merge these dictionaries by summing the counts for each word. ### Example Output: Given the file contents `"This is is is, an example"`, running the script might produce:
1
2
3
4
{"This": 1, "is": 2}
{"is,": 1, "an": 1, "example": 1}
{}
{}
Each line represents the word counts from a different chunk of the file.
