How to install the ta-lib with Anaconda?

[thomas2004ch]

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?

[thomas2004ch]

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?

[mrjbq7]

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.

try:

conda install -c quantopian ta-lib 

[kawong14]

^ it is depreciated for python 3.6

[masdeseiscaracteres]

I'm currently working on a conda-forge recipe for this library:
conda-forge/staged-recipes#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:

1. Install nose
   pip install nose
2. 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

[masdeseiscaracteres]

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

[masdeseiscaracteres]

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.

[asdf8601]

@masdeseiscaracteres it works on windows 10, 64 bit, using miniconda4 and pyhton36.

[masdeseiscaracteres]

Cool! Let's go then for the win32 and Unix wheels

[manisaivecha341]

it shows me that the python doesnot support that type of wheel format
I am using windows 8 64 bit version with python3.6
