Installation On Windows 8 64-Bit?

[pcawthron]

I've been looking at installing ta-lib on Windows 8 64-bit but I am not confident. Here are my actions after deleting any previous python versions:

• Install VS2010 Ultimate
• Download ta-lib-0.4.0-msvc.zip and extract to c:\ta-lib
• Open C:\ta-lib\c\ide\vs2005\lib_proj\ta_lib.sln and compile 6 builds to 64-bit without errors
• Because I wanted my binaries to be used I deleted everything apart from:
  (As downloaded)
  C:\ta-lib\c\include\ta_abstract
  C:\ta-lib\c\include\ta_common
  C:\ta-lib\c\include\ta_defs
  C:\ta-lib\c\include\ta_func
  C:\ta-lib\c\include\libc
  (Produced by VS2010)
  C:\ta-lib\c\bin\ta_regtest
  C:\ta-lib\c\bin\ta_regtest_cdr
  C:\ta-lib\c\bin\gen_code
  C:\ta-lib\c\bin\gen_code_cdr
  C:\ta-lib\c\lib\ta_func_cdr
  C:\ta-lib\c\lib\ta_libc_cdr
  C:\ta-lib\c\lib\ta_abstract_cdr
  C:\ta-lib\c\lib\ta_common_cdr
• Following advice from here I amended setup.py to:
  if sys.platform in ("linux2", "darwin"):
  include_talib_dir = "/usr/local/include/"
  lib_talib_dir = "/usr/local/lib/"
  elif sys.platform == "win32":
  include_talib_dir = r"c:\ta-lib\c\include"
  lib_talib_dir = r"c:\ta-lib\c\lib"
• Also from advice here I amended talib.c to:
  #if defined(WIN32) || defined(MS_WINDOWS)
  #define _USE_MATH_DEFINES
  #define isnan(x) _isnan(x) /* Added PC 2012-11-20 _/ << added - is this needed in VS2010?
  #endif
  #include <math.h>
  #define __PYX_HAVE__talib
  #define __PYX_HAVE_API__talib
  #include "stdio.h"
  #include "stdlib.h"
  #include "numpy/arrayobject.h"
  #include "numpy/ufuncobject.h"
  #include "math.h"
  #include "ta_libc.h" << amended
  #ifdef OPENMP
  #include <omp.h>
  #endif / _OPENMP */
• I then installed python 2.7 64-bit and sys.maxsize confirms as 2^63-1
• I installed 64-bit binaries of numpy and Cython from http://www.lfd.uci.edu/~gohlke/pythonlibs/
• I found I had to use SET VS90COMNTOOLS=%VS100COMNTOOLS%

Now the problem. When I run 'python setup.py install' I get hundreds of warnings and errors like:

talib.c(2392) : warning C4133: '=' : incompatible types - from 'PyArrayObject *' to 'PyObject *'
.
.
talib.obj : error LNK2019: unresolved external symbol TA_GetVersionString referenced in function inittalib
build\lib.win-amd64-2.7\talib.pyd : fatal error LNK1120: 319 unresolved externals

The second time I run it I get 'skipping talib.c Cython extension (up-to-date)'. So my binaries are rubbish, right? But talib.pyd has been created.

In python I can 'import talib' and do the simple test:

data = numpy.random.random(100)
output = talib.SMA(data)

So have I got a 64-bit install? Or have I somehow got a 32-bit version by accident?

I suspect I am fooling myself. As a more complete test I installed PyAlgoTrade (see http://gbeced.github.com/pyalgotrade) which uses ta-lib and successfully ran the 204 tests in the test suite.

The link errors seem like they would be real errors, and I would have thought would prevent the C module from being used properly...

But if you can use talib.SMA and the pyalgotrade tests then it would seem to be working...?

I've just installed 64-bit IPython and I'm playing in there. I get:

In [12]: talib.version
Out[12]: '0.4.0 (Nov 20 2012 17:51:48)'

which was when I ran 'python setup.py install'

In[13]: sys.maxsize
Out[13]: 9223372036854775807L

Is there anything else I can check?

I made some changes to fix the problem using isnan, are there other changes I can make to help Windows installations be easier?

Hi, I'm trying to install talib in python 3 for windows 10 64bits, I really don't understand how to do ... how could I compile?

[mrjbq7]

Follow the directions in the readme? https://github.com/mrjbq7/ta-lib/blob/master/README.md#windows

yes, but so far it has been impossible to install ta-lib and I really need the library

sí, pero hasta ahora ha sido imposible instalar ta-lib y realmente necesito la biblioteca

import talib as ta
ModuleNotFoundError: No module named 'talib'

You have to install the underlying TA-Lib C library in 64-bit. After that you can install this wrapper.

I already did all this:

Download and Unzip ta-lib-0.4.0-msvc.zip
Move the Unzipped Folder ta-lib to C:
Download and Install Visual Studio Community 2015
Remember to Select [Visual C++] Feature
Build TA-Lib Library
From Windows Start Menu, Start [VS2015 x64 Native Tools Command Prompt]
Move to C:\ta-lib\c\make\cdr\win32\msvc
Build the Library nmake

but in this case:
"Build the Library nmake"
the only thing I did was write on nmake console .. is something else missing?

[pcawthron]

There is a pre-compiled 64-bit version of the TA-Lib C library at https://github.com/afnhsn/TA-Lib_x64 which I installed today on Windows 10 with Python 2.7.16 and it works without issue. I simply deleted my old C:\talib and unzipped the 64-bit to a folder with the same name.
