MB Utils

A collection of utility functions and tools to simplify common Python development tasks. This package provides various helper functions for logging, file operations, S3 interactions, and more.

Features

• Logging: Easy-to-use logging setup with file handlers
• File Operations: Path checking and validation
• Decorators: Useful decorators for deprecation warnings and retry logic
• Image Verification: Validate and verify image files
• S3 Integration: Simplified AWS S3 file and directory operations
• Utilities: Various helper functions including timing and batching

Installation

Install the package using pip:

pip install mb_utils

Usage

Logging

from mb_utils.src.logging import logger

logger.info("This is an info message")
logger.error("This is an error message")

Path Checking

from mb_utils.src.path_checker import check_path

check_path(path_list,max_workers=16)

Retry Decorator

from mb_utils.src.retry_decorator import retry

@retry(max_retries=3, delay=1)
def might_fail():
    pass

S3 Operations

from mb_utils.src.s3 import upload_file, download_file, upload_dir, download_dir

# Upload a single file
upload_file('local_file.txt', 'bucket-name', 'remote_file.txt')

# Download a file
download_file('bucket-name', 'remote_file.txt', 'local_file.txt')

Profiling

The profiler module provides utilities for performance analysis of your Python code.

Function Profiling with SnakeViz

from mb_utils.src.profiler import run_with_snakeviz

@run_with_snakeviz(save_only=False)  # Opens SnakeViz automatically
def process_data(data):
    pass

# Or use as context manager
with run_with_snakeviz():
    pass

Line-by-Line Profiling

from mb_utils.src.profiler import line_profile

@line_profile
def process_item(item):
    result = item * 2
    return result

Simple Timing

from mb_utils.src.profiler import time_it

@time_it
def expensive_operation():
    pass

Memory Profiling

from mb_utils.src.profiler import MemoryProfiler

def process_large_data():
    with MemoryProfiler() as mem:
        data = [0] * 10**6

Comprehensive Profiling

from mb_utils.src.profiler import profile_function

@profile_function(
    enable_line_profiling=True,
    enable_memory_profiling=True
)
def analyze_data(data):
    # Will run with multiple profiling tools
    pass
