In the previous section you made your package “pip installable” by creating a setup.py file.
You then installed the package, effectively making accessible between different analysis directories.
However, a package is never set in stone: as you work on your analyses, you will almost certainly likely make changes to it, for instance to add functionalities or to fix bugs.
You could just reinstall the package each time you make a modification to it, but this obviously becomes tedious if you are constantly making changes (maybe to hunt down a bug) and/or testing your package. In addition, you may simply forget to reinstall your package, leading to potentially very frustrating and time-consuming errors.
pip has the ability to install the package in a so-called “editable” mode.
Instead of copying your package to the package installation location, pip will just
write a link to your package directory.
In this way, when importing your package, the python interpreter is redirected to
your package project directory.
To install your package in editable mode, use the -e option for the install command:
# In directory tstools-dist/
pip install -e .
pip uninstall tstoolststools is not among them
Hint: Use pip --help to get alist of available pip commands.tstools in editable mode.tstools.vis.plot_trajectory_subset so that it returns the maximum value
over the trajectory subset, in addition to the figure and axis.
Hint: You can use the numpy function amax to find the maximum of an array.analysis1/data/timeseries1.csv between
t=0 and t = 4 ?In editable mode, pip install just write a file <package-name>.egg-link at the package
installation location in place of the actual package. This file contains the location of the
package in your package project directory:
cat ~/python-workshop-venv/lib/python3.8/site-packages/tstools.egg-link
/home/thibault/python-packaging-workshop/tstools
