Aws glue job to install python wheel that depends on another wheel specified in

When working with AWS Glue jobs, it is common to encounter situations where you need to install a Python wheel that depends on another wheel specified in the code. In this article, we will explore three different ways to solve this problem using Python.

Option 1: Using the subprocess module

The subprocess module in Python allows us to spawn new processes, connect to their input/output/error pipes, and obtain their return codes. We can leverage this module to execute shell commands within our Python code.

import subprocess

# Install the dependent wheel first
subprocess.call(['pip', 'install', 'dependent_wheel'])

# Install the main wheel
subprocess.call(['pip', 'install', 'main_wheel'])

This approach uses the subprocess.call() function to execute the pip install command for both the dependent wheel and the main wheel. By running these commands sequentially, we ensure that the dependent wheel is installed before the main wheel.

Option 2: Using the os module

The os module in Python provides a way to interact with the operating system. We can use it to execute shell commands and manage the environment variables.

import os

# Install the dependent wheel first
os.system('pip install dependent_wheel')

# Install the main wheel
os.system('pip install main_wheel')

In this approach, we use the os.system() function to execute the pip install command for both the dependent wheel and the main wheel. Similar to the previous option, the dependent wheel is installed before the main wheel.

Option 3: Using the subprocess module with pipenv

If you prefer using pipenv to manage your Python dependencies, you can modify the first option to work with pipenv instead of pip.

import subprocess

# Install the dependent wheel first
subprocess.call(['pipenv', 'install', 'dependent_wheel'])

# Install the main wheel
subprocess.call(['pipenv', 'install', 'main_wheel'])

This approach is similar to the first option, but it uses the pipenv install command instead of pip install. Make sure you have pipenv installed and configured properly before using this option.

After exploring these three options, it is clear that the best approach depends on your specific requirements and preferences. If you are already using pipenv, option 3 might be the most suitable for you. Otherwise, options 1 and 2 provide straightforward solutions using the subprocess or os module, respectively.

Choose the option that aligns with your project’s needs and enjoy hassle-free installation of Python wheels in your AWS Glue jobs!
