I recommend removing this line from the notebook and pointing users to Pyomo's installation instructions if they need any of the optional dependencies. My guess is that a standard conda install will already include any optional Pyomo dependencies used in these notebooks.
pyomo.extras has been removed, and readers are provided a link to the Pyomo installation instructions. I also took this opportunity to convert the repository to JupyerBook. Thanks for updates!
The "Installing Pyomo" notebook (https://github.com/jckantor/ND-Pyomo-Cookbook/blob/master/notebooks/01.01-Installing-Pyomo.ipynb) instructs users to install
pyomo.extras
from conda-forge. This package is no longer maintained andpyomo.extras
has been deprecated and removed from the main Pyomo repo.I recommend removing this line from the notebook and pointing users to Pyomo's installation instructions if they need any of the optional dependencies.
