How to install the ta-lib with Anaconda?
I have tried use the following to install the ta-lib in Anaconda: ... conda install -c quantopian ta-lib ...
But I get message as follow:
Fetching package metadata ............. Solving package specifications: .
UnsatisfiableError: The following specifications were found to be in conflict:
- python 3.6*
- ta-lib -> numpy 1.10* -> python 2.7*
Use "conda info
" to see the dependencies for each package.
How to do?
I'm not sure. In the requirements.txt, it looks like we specify some old versions numpy==1.11.1 and cython==0.24.1. Not sure where you're seeing numpy 1.10*.
What happens if you do condo info ta-lib?
This is what I get:
C:\ProgramData\Anaconda3\Scripts>conda.exe info ta-lib Fetching package metadata ........... NoPackagesFoundError: Package missing in current win-64 channels:
- ta-lib
Btw: Is talib from Quantopian?
No, this is not a Quantopian project. And this is just a lightweight wrapper for a "TA-Lib" C library that has been around for 15 years or so.
Ah, well your conda thing is probably a different issue. Since the underlying TA-Lib library isn't released as 64-bit binary on Windows, you have to build it yourself. Or get a pre-built binary that you can use.
Here is a comment from someone getting it to work with Anaconda 64-bit and the previous comment in that thread has some instructions on how to build it yourself if you don't want to trust whatever binary that download is.
@mrjbq7 I think I fix the problem now. This page is very helful, though it is unofficial. http://www.lfd.uci.edu/~gohlke/pythonlibs/#ta-lib
I'm currently working on a conda-forge recipe for this library: https://github.com/conda-forge/staged-recipes/pull/5772
So far, I have created Windows 64 recipes (for ta-lib 0.4.16) only. It would be nice if someone could give it a try:
Install:
conda install -c masdeseiscaracteres ta-lib
Testing:
- Install nose
pip install nose - Run tests
nosetests -v talib
If everything goes alright, the following is expected:
talib.test_abstract.test_pandas ... ok
talib.test_abstract.test_SMA ... ok
talib.test_abstract.test_STOCH ... ok
talib.test_abstract.test_doji_candle ... ok

It seems something unrelated to TA-lib, it went wrong while uninstalling certifi. Close all Python sessions, IDEs, or Python-related running processes and try again.
I installed it via pip, getting this wheel from https://www.lfd.uci.edu/~gohlke/pythonlibs Now I have ta-lib working with python 3.6 Hope this helps someone else
Yep, that works, but this issue is about installing TA-lib using Anaconda. Having a well-tested and well-defined publicly available build process to build conda recipes is also useful to build pip wheels. This will help not only Windows users but those in Unix systems as well.
@masdeseiscaracteres it works on windows 10, 64 bit, using miniconda4 and pyhton36.
it shows me that the python doesnot support that type of wheel format I am using windows 8 64 bit version with python3.6
Which is the bitness of your Python interpreter? When starting the Python interpreter in the terminal/command line you may see a line like:
Python 2.7.2 (default, Jun 12 2011, 14:24:46) [MSC v.1500 64 bit (AMD64)] on win32
What does yours say?
That's it then. The packages in https://anaconda.org/masdeseiscaracteres/TA-Lib/files?type=conda are only for 64 bit Python. I have been told conda-forge no longer supports 32 bit builds.
Great! talib running on my Windows10 machine, conda64 and python 3.6 Already made all 26 tests with OK result and run a simple test code calculating some simple indicators.. Thanks a lot
But look at this..interesting..it seems that maybe is it not installed properly? Module 'talib' has no 'EMA' member
@masdeseiscaracteres here with Windows 10 64bit and Python 3.6 install so fine. Now, I'will test the lib work.
#AllForABetterBrazil
example:
upperband, middleband, lowerband = ta.BBANDS(df['Close'], timeperiod=n, nbdevup=2, nbdevdn=2, matype=0)
Module 'talib' has no 'EMA' member
Module 'talib' has no 'BBANDS' member
but the tests went ok.. what´s wrong?
@jorgeog96 Are you trying to import it from a python shell that was started from the git checkout directory? That would cause it to find/load the wrong ta-lib module.
I am not pretty sure...but you´re right! If I trying to reproduce the code using jupyter notebook (but my same environment) the thing is OK! but using visual studio code with that environment in an anaconda terminal (inside VS) the code is wrong and get the wrong module. What is the problem?
You can see where the module code is loading from:
This is what a "system" install would generally look like:
>>> import talib
>>> talib.__file__
'/usr/local/lib/python3.6/site-packages/talib/__init__.py'
This is what "loading from a git checkout" might look like:
>>> import talib
>>> talib.__file__
'/home/username/ta-lib/talib/__init__.py'
ok, thank u for your help @mrjbq7 , definitely it´s the first way with the "system" install. I´ve tried in both terminals: original anaconda prompt and visual studio anaconda integrated prompt (where I usually code and try out my scripts). So, how can I fix that import error from the scripts written when I use visual studio code?
This is really curious: I import talib package as ta and then I add code to do a RSI calculation using ta.RSI (i.e.):
rsi2 = ta.RSI(df.Close.values,14)
The thing is that VSCode is giving me error saying: E1101:Module 'talib' has no 'RSI' member. But when I use my command prompt Anaconda in VSCode and run: python printPair.py IS RUNNING and calculating the array rsi2 perfectly!
I am comparing the values given from talib with a rsi function "hand-made" and the values are the same. So this is really weird. Maybe it is VSCode python interpreter fault? or something like that? Maybe python interpreter from VSCode is using a "loading from a git checkout"? and getting the wrong package? Because anaconda prompt is running ok! @mrjbq7
I'm not sure how your VSCode is setup, but maybe if you print out:
>>> import sys
>>> sys.path
You can see where the code is being loaded from...
conda install -c quantopian ta-lib depend on python2 version but I use python3 conda install -c developer ta-lib is OK! My system is osx.

happyHou, this is great, how do I create a new conda package for python 3.7? Any pointers appreciated.

[Windows 10, 64 bit, Anaconda ]I am using windows 10 64bit, when I tried to install ta-lib faced similar issues however this youtube video([https://www.youtube.com/watch?v=VJyNArEU0ws&ab_channel=QuantAlpha]) solved all of my issues and now I am using ta-lib in my anaconda environment just fine. hope this helps
