ImportError: tools/python/lib/python3.9/lib-dynload/math.so: undefined symbol: PyFloat_Type

I am using Python 3.9 on Linux. The python installation structure looks like:

/tools/python/bin - containing python executable
/tools/python/lib/libpython3.9.so 
/tools/python/lib/python3.9/lib-dynload/*

I am linking a x.so with libpython.so and trying to run it. And when I run a simple python script test.py(present in /share/python) that looks like:

import unittest
import math

class Test_2(unittest.TestCase):
def test_distance(self):
    self.assertAlmostEqual(box1.distance(box2), math.sqrt(2))

def suite() :
        suite = unittest.TestSuite()
        suite.addTest(unittest.makeSuite(Test_2))
        return suite

It simply gives the following error in the log:

ImportError: Failed to import test module: test
Traceback (most recent call last):
File "/share/python/test.py", line 3, in <module>
import math
ImportError: /tools/python/lib/python3.9/lib-dynload/math.so: undefined symbol: PyFloat_Type

I have set PYTHONPATH as : /share/python and PYTHONHOME as : /tools/python And appended LD_LIBRARYPATH with /tools/python/lib so that it finds libpython3.9.so But still get the above import error: "math.so: undefined symbol: PyFloat_Type" Can someone pls help me in this issue.

Following is the output:
