issues importing in python3 #9

Closed seth-a closed 6 years ago

seth-a commented 6 years ago

I don't see python3 support or lack of support mentioned anywhere, although that may be the root of this problem. In any case, I can import and use nufft with no problems in python2.7, but running in python3 gives the following error. Any suggestions how to fix this are appreciated.


Python 3.5.2 (default, Nov 23 2017, 16:37:01)

And fixed it. I had to remove the files put in place by "python setup.py install", then ran "python3 setup.py install".
