ValueError: Symbol table not found - numpy

Question

I'm trying to install scikit-learn; following the instructions, I downloaded the source and attempted to install it with python setup.py install, however the installation is interrupted at:
File "C:\Users\Alpine\Anaconda\lib\site-packages\numpy\distutils\mingw32ccompi
ler.py", line 278, in generate_def
raise ValueError("Symbol table not found")
ValueError: Symbol table not found
I've also tried using easy_install -U scikit-learn, although end up with the same error.
Using conda install scikit-learn appeared to install the conda-3.4.1-py27_0.tar.bz2 and numpy-1.8.1-py27_0.tar.bz2 packages, and for safe measure I ran conda update anaconda, although I'm still receiving the same error.
Would anybody know how to work around this?

Answer 1

This solution will take care of "symbol table not found" error from numpy (or any other package ) on windows machine
sklearn people have provided good solution for this over here
http://scikit-learn.org/stable/developers/advanced_installation.html#building-on-windows
you can find instruction for Linux and mac on same page
now just follow these steps
32-bit Python
For 32-bit python it is possible use the standalone installers for microsoft visual c++ express 2008 for Python 2 or Microsoft Visual C++ Express 2010 for Python 3.
Once installed you should be able to build scikit-learn without any particular configuration by running the following command in the scikit-learn folder:
python setup.py install
64-bit Python
For the 64-bit architecture, you either need the full Visual Studio or the free Windows SDKs that can be downloaded from the links below.
The Windows SDKs include the MSVC compilers both for 32 and 64-bit architectures. They come as a GRMSDKX_EN_DVD.iso file that can be mounted as a new drive with a setup.exe installer in it.
**For Python 2 you need SDK v7.0: MS Windows SDK for Windows 7 and .NET Framework 3.5 SP1 -> https://www.microsoft.com/en-us/download/details.aspx?id=18950
For Python 3 you need SDK v7.1: MS Windows SDK for Windows 7 and .NET Framework 4** -> (can't post link as i need atleast 10 reputation point )
Both SDKs can be installed in parallel on the same host. To use the Windows SDKs, you need to setup the environment of a cmd console launched with the following flags (at least for SDK v7.0):
cmd /E:ON /V:ON /K
Then configure the build environment with:
SET DISTUTILS_USE_SDK=1
SET MSSdk=1
"C:\Program Files\Microsoft SDKs\Windows\v7.0\Setup\WindowsSdkVer.exe" -q -version:v7.0
"C:\Program Files\Microsoft SDKs\Windows\v7.0\Bin\SetEnv.cmd" /x64 /release
after typing above commands in cmd as soon as you hit enter the window will be changed lil bit ( font color changed to green ) now go to directory where you have downloaded sklearn zip file from git hub then un-zip it
and go to directory where you can find setup.py
run command
python setup.py install
if it's not recognizing python then you migh have missed this command
cmd /E:ON /V:ON /K
so till now if u have done everything correct then your package will be installed without any difficulties
