I think that the error might be in FUSED-Wind, I will try to see if I can fix it there.

Could you tell me how you have installed topfarm? Which OS are you running it on? Assuming you are running the install_all.sh script, try to rerun it. I have updated the remote_install.txt so that it uses the latest version of FUSED-Wind. That might be where the bug is coming from.

Edit: otherwise try to update FUSED-Wind to its latest version on github.com:

pip install -e  git+http://github.com/FUSED-Wind/fusedwind.git#egg=fusedwind

Hi Pierre,

I am trying to run TOPFARM under Windows 7. I installed it following your instructions given in github using Python v2.7.9. I used the command pip install -r http://raw.githubusercontent.com/DTUWindEnergy/TOPFARM/master/remote_install.txt after installing openmdao in version 10.3.2.

I had to ad a setup.py file in the fusedwake package with the following content:

from setuptools import setup, find_packages

##################################################################### kwargs = {'author': 'DTU WInd Energy and NREL NWTC', 'author_email': 'TBD', 'classifiers': ['Intended Audience :: Science/Research', 'Topic :: Scientific/Engineering'], 'description': 'Framework for Unified Systems Engineering and Design of Wind Plants', 'include_package_data': True, 'install_requires': ['openmdao.main'], 'keywords': ['openmdao'], 'license': 'Apache v. 2.0',

'maintainer': '',

'maintainer_email': '',

'name': 'fusedwake', 'packages': find_packages(),

'url': '',

'version': '0.1', 'zip_safe': False}

setup(**kwargs)
##################################################################

Unfortunately your update did not have any effect :-(
