issue with spams installation

[andebag]

Hi, I am new to coding / using python and I am having some issues installing SPAMS on my system. I have python 2.7.16, on windows. I was able to successfully install all the other packages, but I keep getting errors when I try to pip install spams. When I try to do:

pip install --index-url https://test.pypi.org/simple/ spams

I get:

Does this mean I have a problem with my C++ program? I installed it properly but I'm really not sure what the issue is... any ideas to point me in the right direction?

Hi @andebag ,

I have no experience with Windows, but it definitely an installation problem of the SPAMS library. Did you try checking on their website for help?

@fullbat, do you have any insight?

[andebag]

@daducci
Thanks for the response. Yes their website doesn't seem to have info on this problem. I contacted the developers and am waiting for a response. I'm really stumped on this at the moment. If I can't figure it out I'm considering running a virtual machine with Ubuntu at trying it from there. Inconvenient, but an option I guess.

Hi @andebag
I would try to compile with C++14 and see if it's only a problem of the compiler.

[andebag]

Hey @fullbat
I originally was using the version offered for python 2.7 shown here
https://www.microsoft.com/en-us/download/details.aspx?id=44266

I'll try installing VC++14, and let you know how that goes. According to the wiki for it though it is not the best for it.
https://wiki.python.org/moin/WindowsCompilers
Fingers crossed.

Still not working. I might just uninstall everything and start over if it seems like things aren't communicating properly. What versions of everything do you recommend?

I saw on a forum that AMICO works best with python 2.7 so I used that.

Should I used the most up to date version of everything?

Or do you recommend I make a linux virtual machine and try there?

@andebag
I've just installed successfully the last version of AMICO with python 3.5 and the default g++ compiler on Ubuntu 16.04 LTS (unfortunately I don't have experience on Windows OS).
Maybe is good to start from a clean environment and I suggest to move to python 3.

After a lot of troubleshooting and digging around I found this for AMICO installation for Windows using Anaconda:

https://gist.github.com/pangyuteng/5df295faf19d7474d3c3e86b90c2654a#file-readme-md

Just tested it and it produces identical results to running the pure NODDI matlab toolbox. I still don't understand why trying to use just python 2.7 on it's own would not work, but here we are. Thanks again for the help and suggestions guys!
