Python 3.10.4 scikit-learn import hangs when executing via CPP

Python 3.10.4 is embedded into cpp application. I'm trying to import sklearn library which is installed at custom location using pip --target.

sklearn custom path (--target path) is appended to sys.path.

Below is a function from the script which just prints the version information.

Execution using Command Line works well as shown below.

python3.10 -c 'from try_sklearn import *; createandload()'

Output

[INFO ] [try_sklearn.py:23] 3.10.4 (main, Aug  4 2023, 01:24:50) [GCC 4.8.5 20150623 (Red Hat 4.8.5-16)]
[INFO ] [try_sklearn.py:24] sklearn /users/xxxx/temp/python/scikit-learn/sklearn/__init__.py Version = 1.5.1

The same script when called using CPP, hangs at

import sklearn

Other libraries like pandas, numpy etc works without any issues.

Solution

    Looks like Scipy and Numpy do not support Embedded python
