[Neuroimaging] [dipy] Issues trying to install dipy

[Jon Haitz Legarreta]

Hi there,
I'm a newbie to dipy.

I was trying to follow the instructions in [1] to have dipy installed from
the source code, so that I could execute the dipy examples.

I'm using Windows 10 and Anaconda 3.

When trying to execute
*python setup.py develop*

the Anaconda prompt yields an error that says in the end:


*File: "C:\Anaconda3\lib\distutils\cygwinccompiler.py", line 126,
__init__if self.ld_version >= "2.10.90":TypeError: unorderable types:
NoneType() >= str()*

I've been googling for a solution without success.

I don't know whether this looks like Anaconda3 is trying to use cygwin
instead of mingw32, and whether that is the root cause.

In either case, does anyone know how to solve the issue?

Attached is the trace (it's short) of the error if this is of any help.


Thank you,
JON HAITZ
