Session Info 2

0.4.1 · active · verified Tue Apr 14

Session Info 2 is a Python library that prints detailed version information for all currently imported packages and system details, useful for debugging and reproducibility. It's an improved successor to the original `session-info` library. The current version is 0.4.1, with releases occurring every few months to add features and improvements.

Warnings

gotcha This library (`session-info2`) is a distinct successor to the original `session-info` package. While the primary import module is similar (`session_info`), their implementations and features differ. Ensure you install `session-info2` if you intend to use the newer features and improved package discovery.
Fix: Confirm you have installed `session-info2` (and not `session-info`) using `pip show session-info2`. If migrating, be aware of behavioral changes.
breaking In version 0.1.2, the default output format for `session_info.show()` changed from JSON to plain text (or rich terminal output). If your scripts relied on parsing JSON directly from the default output, you now need to explicitly specify `session_info.show(display_mode='json')`.
Fix: For JSON output, call `session_info.show(display_mode='json')` or, for v0.4+, `print(session_info.show().format('json'))`.
gotcha The `.format('markdown' | 'html' | ...)` method was introduced in v0.4. If you are on an older version and need formatted output, you must use the `display_mode` argument directly, e.g., `session_info.show(display_mode='markdown')`.
Fix: Upgrade to `session-info2>=0.4` to use the `.format()` method, or use `session_info.show(display_mode='...')` for older versions.

Install

pip install session-info2 Install with pip

Imports

show
```
from session_info import show
```
The package is `session-info2` but the main module to import is `session_info`.

Quickstart

The most common way to use `session-info2` is to simply call `session_info.show()`. This will print a comprehensive summary of your Python environment, including package versions and system details, directly to the console. As of v0.4, you can also use the `.format()` method on the returned object for specific output types.

import session_info

# Print session information to stdout
session_info.show()

# To get formatted output (e.g., markdown) in v0.4+
# result = session_info.show(display_mode='text') # captures string for earlier versions
# print(result)

# In v0.4+, you can also chain .format()
# print(session_info.show().format('markdown'))
