ta-lib on mac m1 - Githubissues

wilker06 commented 1 year ago

I used and liked ta-lib on Mac m1 with python3.10. For some reason, I moved on to 3.11. Unfortunately, I could not make ta-lib running again. For example, applying WMA the error '... WMA not found in init' pops up. Could you kindly advise how to fix th issue.

Follow the directions in the README. $ python3.11 -m pip install ta-libMake sure the architectures match.

I tried everything recommended in readme ....

arch -arm64 brew install ta-lib: installs version 0.4.0
python3.11 -m pip install --no-cache-dir ta-lib: installs 0.4.25 with the comment 'Successfully installed ta-lib-0.4.25' Using WMA() in a method programmed with PyCharm 2022.3.3 (Professional Edition) WMA() I am notified "Cannot find reference 'WMA' in 'init.py'", but __function_groups__ = { .. } include 'WMA' in group 'Overlap Studies'

Ignoring this and running any code that include ta-lib import and a method with WMA, it ends up in a lengthy error message even if the method with WMA is not called. Traceback (most recent call last): File "/Applications/PyCharm.app/Contents/plugins/python/helpers/pydev/pydevconsole.py", line 364, in runcode coro = func() ^^^^^^ File "", line 1, in File "/Applications/PyCharm.app/Contents/plugins/python/helpers/pydev/_pydev_bundle/pydev_umd.py", line 198, in runfile pydev_imports.execfile(filename, global_vars, local_vars) # execute the script ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/Applications/PyCharm.app/Contents/plugins/python/helpers/pydev/_pydev_imps/_pydev_execfile.py", line 18, in execfile exec(compile(contents+"\n", file, 'exec'), glob, loc)

Another comment: most common is the message: ImportError: dlopen(/Users/.../GitHub/Trading/venv/lib/python3.11/site-packages/talib/_ta_lib.cpython-311-darwin.so, 0x0002): symbol not found in flat namespace '_TA_ACOS'

Sounds like a mixed architecture issue. You should uninstall it and reinstall. You shouldn’t need to arch -arm64 if brew is native in /opt.Instead of pycharm and the virtual env, just get it working in the terminal first. It’s 100% works and supported.

Hi John,

I followed your advice to build a new, clear python application:

I deleted all python packages, removed everything about python - using the terminal
Reinstalled package python 3.10, ib_insync, ….
Run simple test code in PyCharm:

import talib as ta

print('soso‘)

It ends up with the error:

Traceback (most recent call last): File "/Users/…/GitHub/Trading_310/test.py", line 1, in import talib as ta File "/Users/.../GitHub/Trading_310/venv/lib/python3.10/site-packages/talib/init.py", line 93, in from ._ta_lib import ( ImportError: dlopen(/Users/... /GitHub/Trading_310/venv/lib/python3.10/site-packages/talib/_ta_lib.cpython-310-darwin.so, 0x0002): symbol not found in flat namespace ‚_TA_ACOS'

Running the test code with the terminal.

Last login: Thu Mar 30 20:26:49 on ttys000 cd '/Users/... /GitHub/Trading_310/' && '/usr/local/bin/python3' '/Users/... /GitHub/Trading_310/test.py' && echo Exit status: $? && exit 1 ... @MBP-von-Kersten ~ % cd '/Users/... /GitHub/Trading_310/' && '/usr/local/bin/python3' '/Users/... /GitHub/Trading_310/test.py' && echo Exit status: $? && exit 1 Traceback (most recent call last): File "/Users/... /GitHub/Trading_310/test.py", line 1, in import talib as ta ModuleNotFoundError: No module named 'talib' ... @MBP-von-Kersten Trading_310 %

I attach also a screenshot of the pyCHharm Project window

Any idea? Thank you in advance for your kind advice!

Best regards,

Kersten

Have you tried:

# check that it's using ``/opt`` which is for arm64 builds

$ which brew
/opt/homebrew/bin/brew

$ brew install ta-lib
$ export TA_INCLUDE_PATH="$(brew --prefix ta-lib)/include"
$ export TA_LIBRARY_PATH="$(brew --prefix ta-lib)/lib"
$ python3.11 -m pip install ta-lib

Hi John,

I got it work again, found some Python traces from earlier installations, very deep at the system.

Kind regards

here is what worked for me (Apple M2 Max, Sonoma 14.4)

python3.11 pip uninstall ta-lib

export HOMEBREW_PREFIX=/opt/homebrew #set to your homebrew prefix export CPPFLAGS="$CPPFLAGS -Xpreprocessor -fopenmp" export CFLAGS="$CFLAGS -I/usr/local/opt/libomp/include" export CXXFLAGS="$CXXFLAGS -I/usr/local/opt/libomp/include" export LDFLAGS="$LDFLAGS -Wl,-rpath,/usr/local/opt/libomp/lib -L/usr/local/opt/libomp/lib -lomp"

python3.11 -m pip install --no-cache-dir ta-lib

@iKpoxa: thank you for the advice. As I already wrote on Apr 7, 2023 I followed John's advice and got it work again. Works fine since!
