Fix TensorFlow on Python 3.8 logger issue

Browse Source 
This fix tries to address the issue raised in 33799
where running tensorflow on python 3.8 (Ubuntu 18.04)
raised the following error:
```
TypeError: _logger_find_caller() takes from 0 to 1 positional arguments but 2 were given
```

The issue was that findCaller changed in Python 3.8

This PR fixes the issue.
