I ran the pip install TA-Lib with the following error message:

Did you install the TA-Lib C library first? brew install ta-lib On the Mac. See README for more information.

Hi, I've installed ta-lib with Homebrew, but installation using pip3 doesn't work. So, I've tried to install using setup.py, manually adding the path where ta-lib is stored and it works. Nevertheless, now when I import talib and run the code, I have this error:

File "/Users/Urnyx05/Finance/lib/python3.9/site-packages/talib-0.4.19-py3.9-macosx-10.9-x86_64.egg/talib/__init__.py", line 52, in <module> from ._ta_lib import ( ImportError: dlopen(/Users/Urnyx05/Finance/lib/python3.9/site-packages/talib-0.4.19-py3.9-macosx-10.9-x86_64.egg/talib/_ta_lib.cpython-39-darwin.so, 2): Symbol not found: _TA_ACOS Referenced from: /Users/Urnyx05/Finance/lib/python3.9/site-packages/talib-0.4.19-py3.9-macosx-10.9-x86_64.egg/talib/_ta_lib.cpython-39-darwin.so Expected in: flat namespace in /Users/Urnyx05/Finance/lib/python3.9/site-packages/talib-0.4.19-py3.9-macosx-10.9-x86_64.egg/talib/_ta_lib.cpython-39-darwin.so

Do you have any idea how to fix it? I've searched everywhere but I didn't find anything.

It might help to know how you installed the dependency and where it was located?

Hi, I've installed ta-lib with Homebrew, but installation using pip3 doesn't work. So, I've tried to install using setup.py, manually adding the path where ta-lib is stored and it works.

Yes, I'm on M1 MacBook Air.
I installed it with the default command given on the website:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Okay, some suggestions:

1. Is your python built for arm64?

$ file $(which python3.9)
/opt/homebrew/bin/python3.9: Mach-O 64-bit executable arm64

2. If so, it's a little strange the ta-lib python is being built for x86-64, I wonder if you have an issue running the wrong pip3? You can always try this, which always uses the "right" one:

$ python3.9 -m pip install ta-lib

3. Make sure the dependency is built for the same architecture, you can confirm like this:

$ file /opt/homebrew/opt/ta-lib/lib/libta_lib.dylib 
/opt/homebrew/opt/ta-lib/lib/libta_lib.dylib: Mach-O 64-bit dynamically linked shared library arm64

I added paths for /opt/homebrew in 947f480, so it shouldn't require additional work to support. If that's not the case for you, please let me know.

[mrjbq7]

In case you want everything x86-64, you can always prefix your commands with arch -x86_64 like this:

$ brew uninstall ta-lib
$ arch -x86_64 brew install ta-lib

Looking at the commit's path, you have added:
'/opt/homebrew/lib'
instead of
'/opt/homebrew/opt/ta-lib/lib'
Adding the second path, compilation works. But, I still get that issue I was talking about

[mrjbq7]

Did you confirm now that Python and your TA-Lib are the same architecture? It might require “brew link ta-lib” to put links in /opt/homebrew/lib. I feel like you are close to getting it working.

Well, I've just installed the arm version of python and numpy doesn't get installed, so I can't install talib

[mrjbq7]

Yes, that is a problem. I think maybe “brew install numpy” might have some potential of working. You can check the homebrew project for issue related to Apple Silicon compatibility. Your other alternative is to just keep everything you need as x86_64: $ arch -x86_64 brew install python@3.9 $ arch -x86_64 brew install ta-lib $ arch -x86_64 brew link ta-lib $ arch -x86_64 python3.9 -m pip install ta-lib $ arch -x86_64 python3.9 setup.oh install Etc. I develop on an M1 laptop also and have empathy, the development environment is slowly transitioning and a lot of stuff works as arm64, but not everything and when it breaks you can either 1) fix it or 2) wait for a fix or 3) switch to running x86_64 under Rosetta2. The latter works pretty well actually. Best,

Yeah, I think I'll use Rosetta until everything works well on ARM. Thanks a lot

Did you install the TA-Lib C library first? brew install ta-lib On the Mac. See README for more information.
