a pycroscopy ecosystem package

Notebook by Gerd Duscher, 2025

Microscopy Facilities

The University of Tennessee, Knoxville

Model based analysis and quantification of data acquired with transmission electron microscopes

Prerequesites¶

A usual installation of python or python envirnment (like anaconda - recomended) is sufficient.

Installation¶

The installation of pyTEMlib with all its dependencies can be done with the code cell below, right here in this jupyter notebook

In google colab, with always a clean, new python installation, you will have to run this every (run)time.

So this code cell is added to every notebook.

At your own installation, you need to run this codecell only once.

Note:
To update pyTEMLib you need to run this code cell first
Otherwise pyTEMlib is already loaded and you need to restaart the notebook for the new version to take effect

import sys
import importlib.metadata
def test_package(package_name):
    """Test if package exists and returns version or -1"""
    try:
        version = importlib.metadata.version(package_name)
    except importlib.metadata.PackageNotFoundError:
        version = '-1'
    return version

if test_package('pyTEMlib') < '0.2025.12.1':
    print('installing pyTEMlib')
    !{sys.executable} -m pip install  --upgrade pyTEMlib -q

print('done')

Testing Installation¶

Once you have installed pyTEMlib, you will need to import it in every notebook or python instance.

To check installation and version, use the minimal comands below.

import pyTEMlib
print('pyTEMlib version', pyTEMlib.__version__)

pyTEMlib version 0.2025.12.0

Summary¶

You will find the code above in each of the notebooks of this documentation of pyTEMlib to run at google colab.

These code cells are the minimal requirements for the installation.
