Numpy incompatible with Talib

Open JerryYin7 opened this issue 1 year ago • 7 comments

Hi, After I downloaded talib, there is no way for me to run my code. There will be the error message that: File "/Users/guangzhouzuihoudehaonanren/Desktop/intern/intern.py", line 2, in import backtrader as bt File "/Users/guangzhouzuihoudehaonanren/Desktop/intern/quant/lib/python3.12/site-packages/backtrader/init.py", line 86, in from . import talib as talib File "/Users/guangzhouzuihoudehaonanren/Desktop/intern/quant/lib/python3.12/site-packages/backtrader/talib.py", line 34, in import talib File "/Users/guangzhouzuihoudehaonanren/Desktop/intern/quant/lib/python3.12/site-packages/talib/init.py", line 93, in from ._ta_lib import ( File "talib/_ta_lib.pyx", line 1, in init talib._ta_lib ValueError: numpy.dtype size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject Thanks!!!

We do not currently support numpy 2

There are pending issues with cython to support it that need fixing first.

What version should we use? Just downgraded to 1.26.4 and still having issues. Thanks!

It should work with any numpy < 2.

What issues are you having?

I got mine working in a python 3.12 venv, after installing numpy 1.26.4, and talib 0.4.32 Other errors come up now of course, but talib / numpy might be happy now. we'll see....

Released ta-lib 0.5.0 with numpy 2.0 support.

Also released ta-lib 0.4.33 with numpy<2.0 support.
