@auderson and/or others watching, i know it's not ideal but just to get working for py3.11, i was able to use the conda install -c conda-forge libta-lib command to get the base C package, then used pip install ta-lib within the activated conda environment to install the python one, and verified via conda list that ta-lib was there, conda just lists pypi as the channel.

i'm just ignorant enough to seriously wonder if something like conda install -c pypi ta-lib would have worked...

functionally the library imports and "works", but the whole reason i went this conda/etc route was to swap out numpy and pandas for cupy and cudf and use RAPIDS to run things on GPU, and ta-lib chokes up on cupy's device versions of numpy arrays, so, can't win them all i guess...

Requires Python <3.11.0a0, does not install on 3.11.9.

$ conda install -c conda-forge libta-lib
$ pip install pyproject-toml

$ conda install -c pypi ta-lib gives the same error as conda install -c conda-forge ta-lib:

$ conda install -c conda-forge ta-lib

I made an environment in Python 3.10 and installed it there.

conda create --name trading python=3.10 -c conda-forge
conda activate trading
conda install -c conda-forge ta-lib -n trading

Your error is not having the underlying TA-Lib C library installed.

Thanks, via pip installed. But it don't works, for Python 3.11 and 3.10.

$ conda create --name trading311 python=3.11 -c conda-forge
$ conda activate trading311
$ pip install ta-lib

Next, same for Python 3.11 and 3.10:

It's not numpy 2.0 compatible yet, i guess:
