ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 88 from C header, got 80 from PyObject

[DeWaRs1206]

Hello,

I'm trying to use TA-lib on my Ubuntu 18.04 instance. I installed the package using

sudo ./configure
sudo make
sudo make install

and then install ta-lib using pip install ta-lib

When I try to import talib, I got the following error:

>>> import talib
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/user/user/virtualenv/lib/python3.7/site-packages/talib/__init__.py", line 52, in <module>
    from ._ta_lib import (
  File "talib/_ta_lib.pyx", line 1, in init talib._ta_lib
ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 88 from C header, got 80 from PyObject

The only recommendation I found on internet was to install python 3.8 which isn't a possibility for me right now (to many dependencies on my project). Any idea what's the issue could be ?

Thanks in advance.

Am having this issue as well on my server, but not on local Ubuntu. Have u found a fix?

[mrjbq7]

I suspect it’s an issue with pip being different than the Python you want to use.

Try this:

python3.9 -m pip install ta-lib

(Replace python3.9 with whichever Python you are using )

Updated python3 to python3.8 and now the error is not there anymore

[leejh3224]

Updating numpy==1.20.0 also helped in my case. (have used numpy==1.19.5)

[xmatthias]

You might wanna reference https://github.com/pypa/pip/issues/9542 regarding this, as the pip build-behaviour that's causing this is being discussed there.

[dleclair]

I ran into this as well. Looks like updating to numpy==1.20.0 does indeed resolve it but I'm wondering if it will break again the next time numpy puts out another release.

Is the issue here that ta-lib is being installed against the latest available version of numpy which may be different from the version of numpy installed in the runtime environment?

[xmatthias]

numpy is ABI forward compatible - so if you got ta-lib installed once, it'll work, as a new version will always be newer.

During build time, pip installs the latest version (see issue above) in the build environment. If your environment then has a older version, it may break (as shown here).

Apparently, this can be fixed by changing the build-dependency to oldest-supported-numpy - as this will exploit the forward compatibility

[DeWaRs1206]

@mrjbq7 using python3.7 -m pip install ta-lib instead of pip install ta-lib and it worked. (I'm using a virtualenv, so I'm not sure why this is the solution tbh)

this sucks since tensorflow-macos 2.5 is tied to 1.19

[mrjbq7]

What’s the issue?

This Python project doesn’t require new numpy, although the C file that is checked in might be generated with new numpy.

Nothing stops using Cython to generate and install it with other numpy versions?

I’m currently trying to build a Docker container with some libraries, between them are: numpy ;ta-lib.

The problem is that some library requires numpy<=1.19 and when using that version of numpy presents this error:

ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 88 from C header, got 80 from PyObject

That binary incompatibility was fixed in numpy>=1.20, but I can't use that numpy version because of other dependencies that requires numpy<=1.19

There is any way to build a Docker container with ta-lib and numpy<=1.19?

[mrjbq7]

Should work fine. You might need to regenerate the C files using Cython.

You can run “make cython” to do that

I dunno about your Docker integration, but it's there:

$ make cython
cython --directive emit_code_comments=False talib/_ta_lib.pyx

But maybe that's not the way to fix it -- the next release will no longer specify a numpy version, which might make it easier to support various combinations of versions.

[mripani]

Hello! I'm steel dealing with the error

Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/local/lib/python3.8/site-packages/talib/__init__.py", line 93, in <module> from ._ta_lib import ( File "talib/_ta_lib.pyx", line 1, in init talib._ta_lib ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject

I'm currently using numpy==1.21.5 and TA-Lib==0.4.24.

To solve the error I should update to numpy==1.22 but other dependencies that I have work only for numpy<=1.21.*.

Is possible to work with TA-Lib and numpy<=1.21?

[mrjbq7]

I don't specify a version of numpy that's required.

[mrjbq7]

Have you tried doing a git checkout and installing from python setup.py install?

That would allow you to regenerate the C bindings for your local numpy version (make cython)

[keivanK1]

I had the same problem and could solve it by updating the numpy:

pip install --upgrade numpy

I have ta-lib==0.4.24 and numpy==1.22.3

I generate the C files using latest numpy and cython.

Maybe you need to regenerate them for your numpy version.

$ make cython $ python setup.py install

its WORKED with me :) Thank you

Same, pip install --upgrade numpy solved it for me. I had 1.20.3 and upgraded to 1.23.4
