The version of Python I'm using is 2.7.9 (64 bit) with pip 1.5.6 on Windows 7 powershell. I'm trying to install the package fann2 1.0.7, but I receive an error. Here is the full output:

Got the same problem. I tried to open the c file with VS 2013 and rebuild. Similar errors show up. It seems that VS 2013 doesn't like the source c code?

Hey, sorry for not responding sooner. We get a lot of issues opened from Windows users. Could you guys see if one of these:

helps solve the problem?

It seems we are getting c compiling errors during the installation. I've checked others response. They seem to have different issues...

Here is the log:

Se how this user solve the problem: #9 (comment)

Here you will find how install properly the fann libs http://leenissen.dk/fann/wp/help/installing-fann/

Anyway if you find hard the installation you can use a web site that has a working binary of python fann2 v1.07
http://www.lfd.uci.edu/~gohlke/pythonlibs/#fann2

thanks man. I'll give #9 a shot again and try that binary as well. hopefully they will work~

#9 didn't work for me (maybe because I don't know exactly what I'm doing in VS). But I managed to solve the problem by installing the *.whl file available in http://www.lfd.uci.edu/~gohlke/pythonlibs/#fann2

First I installed wheel:

pip install wheel

Then I installed the file "fann2‑1.0.7‑cp27‑none‑win32.whl" that I downloaded:

pip install c:\path\to\file\fann2‑1.0.7‑cp27‑none‑win32.whl

Now fann2 is working, it seems. Please fix this bug. And thanks for your attention!

hey guys! sorry came back too late. I've got it working with Revernus's method! Though I didn't install wheel. went straight ahead for the whl file. Cheers! Thanks guys.

@houssainy

I was facing the same problem and it have been solved by using Revernus method also.

Thank you Revernus!

I'm glad it helped you, guys. I hope developers fix this bug soon, FANN is a great library.

We don't build, test, and deploy on Windows; though, when there's time, I'd like to look into that build error posted. It seems easy enough to fix. Resorting to unsigned third-party binaries isn't an ideal solution for users of this package. I'll see if I can get my Windows machine ready to test this and have something sorted by the end of next month.

I have got the same problem, like FiniteElementries. http://pastebin.com/Tjf6MCdi
I think, the problem is in invalid cast at generated fann2_wrap.cxx by swig.
In addition, it swears on its includes. If I replaced these by includes from FANN-2.2.0-Source, such errors no longer occur.
Used swigwin-3.0.7

Is there a solution to install fann2 from pip? None of the above mentioned solutions worked for me. :(

@magiclevinho See this issue: #25
I ended up cloning and installing this fork that has a fix: https://github.com/randomstuff/fann2
