Error on import under Python 3.11

[Dhaneor]

When importing talib in virtual environment that uses Python 3.11 I get the following error message:

In [1]: import talib as ta

ImportError Traceback (most recent call last) Cell In [1], line 1 ----> 1 import talib as ta

I could not install the package with conda (latest not available on PyPi yet?) because it demands Python to be below version 3.11. I got it installed using the source from Github where this requirement is already updated. The conda installed version in a Python 3.10 environment works just fine, but under 3.11 I get the error message mentioned above.

I don't understand why the file __talib.cpython-311-darwin.so cannot be found, because I can see it in the directory.

The README has all the information on how to install it. You need the underlying TA-Lib C library on the machine. The error is this:Symbol not found: _TA_ACOSInstall TA-lib and then install this Python wrapper.If you are having trouble reading the README installation guide let me know and I can help. On Aug 3, 2023, at 4:31 AM, Dhaneõr @.> wrote: When importing talib in virtual environment that uses Python 3.11 I get the following error message: In [1]: import talib as ta ImportError Traceback (most recent call last) Cell In [1], line 1 ----> 1 import talib as ta File ~/opt/anaconda3/envs/bot311/lib/python3.11/site-packages/talib/init.py:93 89 else: 90 _wrapper = lambda x: x ---> 93 from ._ta_lib import ( 94 _ta_initialize, _ta_shutdown, MA_Type, ta_version, 95 _ta_set_unstable_period as set_unstable_period, 96 _ta_get_unstable_period as get_unstable_period, 97 _ta_set_compatibility as set_compatibility, 98 _ta_get_compatibility as get_compatibility, 99 TA_FUNCTION_NAMES 100 ) 102 # import all the func and stream functions 103 from ._ta_lib import ImportError: dlopen(/Users/dhaneor/opt/anaconda3/envs/bot311/lib/python3.11/site-packages/talib/_ta_lib.cpython-311-darwin.so, 2): Symbol not found: _TA_ACOS Referenced from: /Users/dhaneor/opt/anaconda3/envs/bot311/lib/python3.11/site-packages/talib/_ta_lib.cpython-311-darwin.so Expected in: flat namespace in /Users/dhaneor/opt/anaconda3/envs/bot311/lib/python3.11/site-packages/talib/_ta_lib.cpython-311-darwin.so I could not install the package with conda (latest not available on PyPi yet?) because it demands Python to be below version 3.11.

Thanks for your answer! I did read the installation instructions, and it works fine with Python 3.10.8 and ta-lib 0.4.19 - so the C library should be installed correctly. This error message only pops up with Python 3.11 and ta-lib 0.4.28, installed from the sources downloaded from here.

How did you install it it for python 3.11?You need to install the underlying TA-Lib C library and then pip install ta-lib.On Aug 3, 2023, at 12:57 PM, Dhaneõr @.***> wrote: Thanks for your answer!

Then, when I run test_func.py, I still get the error message. After switching to another environment, it works just fine, though. Shouldn't the installation of the C library be fine, if it works with Python 3.10.8?
