Cannot install ta-lib on Termux. Need help.

[furballcoder]

Hi,

I followed Instructions how to install NUMPY and PANDAS on Termux to successfully get numpy and pandas installed.

However, no luck yet with ta-lib.

I already installed ta-lib dependency through pkg install ta-lib without issue.

I set:

export TA_LIBRARY_PATH=$PREFIX/lib

export TA_INCLUDE_PATH=$PREFIX/include

Running import numpy works fine in Python interpreter.

Running pip install ta-lib results in the following error:

Collecting ta-lib

  Installing build dependencies ... done
  Getting requirements to build wheel ... done
  Installing backend dependencies ... done

      IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

      Importing the numpy C-extensions failed. This error can happen for
      many reasons, often due to issues with your setup or how NumPy was
      installed.

      We have compiled some common reasons and troubleshooting tips at:

          https://numpy.org/devdocs/user/troubleshooting-importerror.html

      Please note and check the following:

        * The Python version is: Python3.11 from "/data/data/com.termux/files/home/py_envs/sdtrade4/bin/python"
        * The NumPy version is: "1.26.4"

      and make sure that they are the versions you expect.
      Please carefully study the documentation linked above for further help.

      Original error was: dlopen failed: cannot locate symbol "PyExc_ValueError" referenced by "/data/data/com.termux/files/usr/tmp/pip-build-env-53btky7m/normal/lib/python3.11/site-packages/numpy/core/_multiarray_umath.cpython-311.so"...

It is strange that import numpy worked fine in Python console, but the same call made during installation of ta-lib resulted in runtime error.

I also looked at similar issue in [python] import numpy as np : r/termux but that's due to missing library imports and import numpy failed immediately in Python console.

Any idea about this issue and suggestion on more things to try?

The latest version of Numpy can be installed using python-numpy.
If you need a different version of Numpy, follow the instructions laid out in

• Instructions how to install NUMPY and PANDAS on Termux #19126

Also thank you for confirming that ta-lib is still being actually used.
We were considering disabling it due to being a standalone library with no apparent dependent packages.
(The ta-lib package predated this policy)

The issue might be related to our ta-lib package currently being out of date.
