I have been trying to install Cython for Python 2.7 on my Window 7 system. In particular, I prefer everything in 64 bits. (In case you wonder, I need Cython because Cython is one of the components I need for another package for some specialized numerical analysis. And x64 is potentially an advantage for storage of large data sets.)
So I downloaded the x64 Python 2.7 from the official website. Got Cython from Christoph Gohlke . The amd64 version for Python 2.7 of course. Before I installed, I added Python 2.7 into the registry with the .reg
file found in Joe DF's answer here . Afterwards, I installed the Visual C++ compiler from here (I don't think it works) and here (but this one should). At this point, I have in my C:\\Program Files (x86)\\Microsoft Visual Studio 9.0\\VC\\bin
directory all of vcvars32.bat
, vcvars64.bat
, vcvars86_amd64.bat
, vcvarsx86_ia64.bat
. I ran vcvars64.bat
and there was no error message.
Subsequently, I followed this page to create a "hello world" test file.
Then, I got this error.
...\Tests>python setup.py build_ext --inplace
running build_ext
building 'hello' extension
error: Unable to find vcvarsall.bat
So I thought to myself: Well, Cython can't find that file because it does not exist. (I searched my whole harddrive for it.) So I copied vcvars64.bat
from ...\\VC\\bin
to \\VC
and changed the name to vcvarsall.bat
. Now vcvarsall error is gone. And ... naturally, a new error emerges.
...\Tests>python setup.py build_ext --inplace
running build_ext

Now I have no idea how to proceed. What should I do? Your help is much appreciated.
(For clarity, I did try setting the compiler to Mingw32. But there are other errors. I am focusing on getting VC to work for now.)
EDIT: I tried using the SDK build environment CMD following the instructions on this page . I received the same error.
In case anyone is currently (2017) facing same error with visual C++ 2015 tools, launch setup again and also select windows 8.1 / 10 SDK depending upon your OS. This will fix basestd.h
error.
If it is still not working, try launching build tools from: C:\\Program Files (x86)\\Microsoft Visual C++ Build Tools.
Another alternative would be, just install anaconda 2 or 3 (64 bit if also you don't want memory errors). It contains all the important packages prebuilt: sklearn, matplotlib, scipy, numpy, pandas and even web development frameworks such as flask.
I encountered this problem while trying to install pandas
in 'develop' mode. I'm up & running now. My environment:
<--
"registered" as system's python distro using WinPython Control Panel application Problems encountered when running python setup.py develop
:
Solution:
<--
this gives you basetsd.h
<--
this gives you the 64-bit compilersC:\\Program Files (x86)\\Microsoft Visual Studio 9.0\\VC\\bin\\vcvars64.bat
to C:\\Program Files (x86)\\Microsoft Visual Studio 9.0\\VC\\bin\\amd64\\vcvarsamd64.bat
. Observe the change in file name.C:\\Program Files (x86)\\Microsoft Visual Studio 9.0\\VC\\bin
to PATH
. This may not be required (I did so before re-installing the SDK w/ Headers & Libs; therefore, the necessity is unknown). At this point, running python setup.py develop
completed successfully and python -c "import pandas; print pandas.__version__"
resulted in the git tag I expected.
[EDIT] Further reading:
For those with Windows 10, download the SDK from here to fix the header file basestd.h
.
I downloaded the .exe, installed and worked great. SDK was ~2.3GB.
Note: For those like me with 64-bit systems who got an additional error:
`LINK : fatal error LNK1158: cannot run 'rc.exe'
error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\x86_amd64\\link.exe' failed with exit status 1158
There is a great answer here which solves the problem by placing the rc.exe
file in the correct folder for your system.
For suggestion, you can try it for build cython 64 bit with setup.py
I'm using Anaconda for python distribution, Microsoft's Windopws SDK 7, and MSVC 12.0.
Firstly, I make library for my cuda function, Second, I run python setup.py build_ext -i for make temp folder (you wil get error), then compile Makefile below,
Mostly, I get this from setup.py when it is compile 32 bit app, then change it for compile 64 bit.

Add these to the visual studio installation directories to your Environment variables

C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\Common7\\Tools
hope it solves the issue.
I could solve this problem by downloading and installing the latest Windows 10 SDK from this link: https://software-download.microsoft.com/download/pr/19041.685.201201-2105.vb_release_svc_prod1_WindowsSDK.iso
but then another problem appeared with (cpython):
error C2039: 'exc_type': is not a member of '_ts'
which I could resolve by declaring additional pointers in
(...\python38\include\cpython\pystate.h)
I found these at line 77:
/* The exception currently being raised */
PyObject *curexc_type;
PyObject *curexc_value;
PyObject *curexc_traceback;
and I add the following just after them (without the first three letters "cur"):
/* The exception currently being raised */
PyObject *exc_type;
PyObject *exc_value;
PyObject *exc_traceback;
