session_info outputs version information for modules loaded in the current session, Python, and the OS.
session_info outputs version information for modules loaded in the current session,
Python, the OS, and the CPU. It is designed as a minimum measure to increase
reproducibility and provides similar information as sessionInfo and
devtools::session_info in R.
session_info is particularly useful when conducting exploratory data analysis in
Jupyter notebooks. Listing the version numbers of all loaded modules after
importing them is a simple way to ensure a minimum level of reproducibility
while requiring little additional effort. This practice is useful both when
revisiting notebooks and when sharing them with colleagues. session_info is meant to
complement more robust practices such as frozen virtual environments,
containers, and binder.
session_info can be installed via pip install session_info. It does not depend on a package
manager to find version numbers since it fetches them from the module's version
string. Its only dependency is stdlib_list, which is used to distinguish
between standard library and third party modules.
session_info can be used from a script like so:
import math
import natsort
import pandas
import session_info
session_info.show()
Output:
Session information:
-----
natsort 7.1.1
pandas 1.2.2
session_info 1.0.0
-----
IPython 7.23.0
jupyter_client 6.1.12
jupyter_core 4.7.1

The default behavior is to only output modules not in the standard library,
which is why the math module is omitted above (it can be included by
specifying std_lib=True). To include not only the explicitly imported
modules, but also any dependencies they import internally, specify dependencies=True.
When session_info is invoked from a Jupyter Notebook,
the output is concealed in <details> tags
and will only show when clicked.
Since this saves visual real estate,
any modules imported indirectly as dependencies
will be included by default
and it looks like this:
----- natsort 7.1.1 pandas 1.2.2 session_info 1.0.0 -----

If you prefer to show the session information without the HTML tags,
you can use session_info.show(html=False) in the notebook
to get the same output as in the first example above.
session_info can also write the module dependencies
to a requirements.txt file,
which is compatible with pip install -r /path/to/requirements.txt.

session_info started as minor modifications of py_session, and as it grew it
became convenient to create a new package. session_info was built with the help of
information provided in stackoverflow answers and existing similar packages,
