Re: [EnergyPlus_Support] WaterHeater:HeatPump not heating from heating element



Were you getting an error with dot_parser of pydot as well?


For anyone struggling to install Eppy, I've taken the following notes during install that could be useful (especially for the above error)

1. Install Python 2.7 x86 (and NOT 3.X)

Make sure the Path variable has "C:\Python27;C:\Python27\Scripts;"


2. Download get-pip

> python get-pip.py


3. Download nump and Download graphviz


4. Install numpy


5. Install graphviz
You get an error
"Error: pydot, couldn't import dot_parser"

   
For anyone else who comes across this, it is due to the changes in pyparsing from 1.x to the 2.x release. To install pydot using pip, first install the older version of pyparsing:

> pip uninstall pyparsing
> pip uninstall pydot
> pip install -Iv https://pypi.python.org/packages/source/p/pyparsing/pyparsing-1.5.7.tar.gz#md5=9be0fcdcc595199c646ab317c1d9a709
> pip install pydot


6. Add "C:\Program Files (x86)\Graphviz2.38" to Path
Path variable has all the following: "C:\Python27;C:\Python27\Scripts;C:\Program Files (x86)\Graphviz2.38"


7. Install Eppy
> pip install eppy

Yes, I've been struggling with getting the one in Eppy to run too. I'll try Inkscape, which I'd forgotten I have installed.


Thanks again.
