How to change TA-Lib C library to arm64?

[jcabourne]

I have recently changed to an M3 mac and i am struggling to get TA-Lib to install correctly.

I have uninstalled and reinstalled TA-Lib multiple times now.

I first performed un-installs as follow: brew uninstall ta-lib pip uninstall ta-lib

Then I followed the instructions in the ReadMe: arch -arm64 brew install ta-lib export TA_INCLUDE_PATH="$(brew --prefix ta-lib)/include" export TA_LIBRARY_PATH="$(brew --prefix ta-lib)/lib" pip install TA-Lib

ERROR: symbol not found in flat namespace '_TA_ACOS'

I think the issue is TA-Lib C Library is not arm64

Comand: file $(brew --prefix ta-lib)/lib/libta_lib.dylib Returns: Mach-O 64-bit dynamically linked shared library x86_64

while everything else is running on arm64, i just cant work out how to switch the C library to arm64 i have tried so many different un/reinstall suggestions from the online forums and have had no luck.

thanks in advance

if you migrated from an intel mac, then your brew is probably /usr/local/ which is the intel location, in the apple silicon native world brew would be in /opt, you can do which brew and see.

you might also have python's installed that are intel.

it only works if your TA-Lib C library (brew install ta-lib) matches your python (brew install python) which matches your ta-lib python module (pip install ta-lib).

The other problem that happens sometimes is the pip isn't the same as the python you want to run so i recommend making sure it is by doing python3.13 -m pip install ta-lib or whatever version you want.

[mrjbq7]

you do not want to do arch -arm64 brew install ta-lib, using the "intel homebrew", that will mess things up. they would prefer you do /usr/local/bin/brew for intel and /opt/homebrew/bin/brew for arm64.

[jcabourne]

Thank you for the quick response.

You're correct it appears i am using /usr/local/bin/brew

What is the best way to switch to opt/?

[mrjbq7]

Install it again using their directions:

https://brew.sh

[mrjbq7]

You'll end up with "two brews", and can decide if you need intel libraries (keep /usr/local homebrew stuff) or not (delete /usr/local homebrew stuff).

[jcabourne]

So i deleted the old brew and reinstall the the new brew in opt/

Unfortunately the brew command stop working so i alias'd the brew command to the opt/ version of brew.

(base) ja*****@Mac ~ % which brew brew: aliased to /opt/homebrew/bin/brew

(base) ja*****@Mac ~ % arch -arm64 brew install ta-lib arch: Can't find brew in PATH

(base) ja*****@Mac ~ %

[mrjbq7]

On my apple silicon mac:

➜  ~ which brew
/opt/homebrew/bin/brew

➜  ~ brew install ta-lib
Warning: ta-lib 0.4.0 is already installed and up-to-date.
To reinstall 0.4.0, run:
  brew reinstall ta-lib

➜  ~ /opt/homebrew/bin/brew install ta-lib
Warning: ta-lib 0.4.0 is already installed and up-to-date.
To reinstall 0.4.0, run:
  brew reinstall ta-lib

You don't need arch -arm64 because the arch of your machine is already arm64.

[jcabourne]

Going through all those commands i have the same output.

But i still get the error:

ImportError: dlopen(/Users/ja***/opt/anaconda3/lib/python3.12/site-packages/talib/_ta_lib.cpython-312-darwin.so, 0x0002): symbol not found in flat namespace '_TA_ACOS'

[jcabourne]

I have just seen that Notebook looks to still be pointing at usr version of brew.

sorry im aware we are moving further away from a TALIB issue now but do you have any idea how to change this to the new brew version

[mrjbq7]

I'm sorry it's frustrating, moving from intel to apple silicon was for me too until i had all this stuff split out.

I would guess your python is still intel, but here's generally how I think about it:

do i have arm64 brew

➜  ~ which brew
/opt/homebrew/bin/brew

do i have arm64 ta-lib

➜  ~ file $(brew --prefix ta-lib)/lib/libta_lib.dylib
/opt/homebrew/opt/ta-lib/lib/libta_lib.dylib: Mach-O 64-bit dynamically linked shared library arm64

do i have arm64 python

➜  ~ file $(which python3.13)
/opt/homebrew/bin/python3.13: Mach-O 64-bit executable arm64

install the arm64 python ta-lib

➜  ~ python3.13 -m pip install ta-lib

or use a venv

    python3.13 -m venv path/to/venv
    source path/to/venv/bin/activate
    python3.13 -m pip install ta-lib

[mrjbq7]

This message /Users/ja**/.zprofile makes me think you need to edit your ~/.zprofile to change it to refer to /opt/homebrew/bin/brew

[mrjbq7]

Note: it is possible for you to run intel python with intel brew with intel ta-lib on apple silicon mac. it just requires keeping your environment consistent.

unless you need a mixed environment (which i do for different dev reasons), i suggest going all apple silicon and removing the intel libraries and python's you used to use.

[mrjbq7]

And you might want to uninstall old ta-lib python first python3.13 -m pip uninstall ta-lib... if it was compiled earlier to just make sure it's reinstalled...

[jcabourne]

.zprofile updated but hasn't fixed the '_TA_ACOS' issue.

Unfortunately i am moving all my python packages to Arm64 as i was having other issues trying to operate the intel python and im now making the effort to get it all running correctly on arm64.

is there a way to dirrectly address the import error?

ImportError: dlopen(/Users/ja***/opt/anaconda3/lib/python3.12/site-packages/talib/_ta_lib.cpython-312-darwin.so, 0x0002): symbol not found in flat namespace '_TA_ACOS'

my bashprofile is still reading

Setting PATH for Python 3.9

The original version is saved in .bash_profile.pysave

PATH="/Library/Frameworks/Python.framework/Versions/3.9/bin:${PATH}" export PATH

do you think this could be the issue?

[mrjbq7]

The bash message seems to relate to system python 3.9, but your install is anaconda python 3.12.

In this case, I personally would probably delete ~/opt/anaconda3/lib/python3.12/site-packages/talib directory and then try and re-install it, making sure that I didn't have any issues with an old export of TA_LIBRARY_PATH or TA_INCLUDE_PATH pointing to an old C library.

If you're sure that ~/opt/anaconda/bin/python3.12 is arm64, and sure that brew is arm64, and sure that brew install ta-lib is arm64, then the last step is making sure that you do ~/opt/anaconda/bin/python3.12 -m pip install ta-lib and have it compile properly as arm64.

[mrjbq7]

Then test it with

$ ~/opt/anaconda/bin/python3.12
Python 3.12.7 (main, Oct  1 2024, 02:05:46) [Clang 16.0.0 (clang-1600.0.26.3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import talib
>>> print(talib.__version__)

[jcabourne]

Unfortunately i just could not get it to work.

All packages have been installed correctly with the correct arm64 all bash and zsh profile are correct but i still get the '_TA_ACOS' error.

It seems to be the only package that is having issues installing so i have decided to migrate to btalib which is working.

hope others manage to get it sorted, thanks for your help @mrjbq7

[mrjbq7]

My best guess is your anaconda python is still intel, but I'm not sure.

$ file ~/opt/anaconda/bin/python3.12
