Crash observed when importing tensorflow and bfloat16 module

[murthy-l]

Bfloat16 module crashes when tried to import along with tensorflow.
Tensorflow supports bfloat16, i am aware of it, but in larger project this is affecting the bfloat16 usage
Simple steps to reproduce the issue

$ python
Python 3.8.10 (default, Nov 26 2021, 20:14:08)
[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

import tensorflow
import bfloat16
Segmentation fault (core dumped)

tensorflow version 2.6.2
bfloat16 version 1.1

In my experiment importing bfloat16 first and then tensorflow did the trick.

But I only tested on a small script, not sure what the root cause is and whether it'll cause issue in a more complex program/project.
