I'm trying to install TALib in Windows, but I'm getting this error:
common.obj : error LNK2019: unresolved external symbol TA_GetUnstablePeriod referenced in function __pyx_pf_5talib_6common_8_ta_get_unstable_period

when I run:
pip install TA-Lib
I already installed Microsoft Visual C++ Compiler for Python 2.7. How can I fix this?
That error is mentioned in the README
in the repository: GitHub Repo
Sometimes installation will produce build errors like this:
func.c:256:28: fatal error: ta-lib/ta_libc.h: No such file or directory compilation terminated.
This typically means that it can't find the underlying TA-Lib library, a dependency which needs to be installed. On Windows, this could be caused by installing the 32-bit binary distribution of the underlying TA-Lib library, but trying to use it with 64-bit Python.
Since your error log contains amd64
it might well be that the 32bit vs 64bit issue is your actual problem.
The library is only distributed in 32-bit format (the compilation/linking dates are from 2007)
Check issue #11, GitHub - Issue #11 for hints on how to compile it yourself.
I had the same issue running Anaconda3/python3.5/JupiterNotebook: Check your version and download the appropriate binary from: https://www.lfd.uci.edu/~gohlke/pythonlibs/#ta-lib
Upload and install:
!pip install TA_Lib-0.4.17-cp35-cp35m-win_amd64.whl
Ta-Lib installation requires that you install the binary dependency. This can be easily installed by installing the whl file. This file can be found in this link: https://www.lfd.uci.edu/~gohlke/pythonlibs/#ta-lib . You can refer to this blog for detailed steps: https://blog.quantinsti.com/install-ta-lib-python/
I had done a parallel run between ta-lib and other packages and also by using jit compiler. But the results of ta-lib were much better. On the internet, you will find many solutions but installing through whl is the best approach.
I hope this helps.
just download the.whl file then save it inside your python libraries file and pip install TA_Lib-0.4.24-cp38-cp38-win_amd64.whl, before that try manually delete any file related to talib
The following steps solved the problem for me:
Note: You will have to check your existing python version using below code and then choose the appropriate file in step 1:
import platform
print(platform.python_version())
