Hotfix - Pyomo update II
Oemof-solph does not work with the latest version of Pyomo (5.7.3). In fact it does work but it takes hours.
If this problem affects you just downgrade Pyomo to 5.7.2 or lower.
pip install pyomo==5.7.2
This hotfix is released to allow installation without manually downgrading Pyomo. Instead of downgrading Pyomo you can just use:
pip install oemof.solph --upgrade
