Error

Error in atexit._run_exitfuncs:
Traceback (most recent call last):
  File "/Users/tmdement/.pyenv/versions/3.9.0/lib/python3.9/site-packages/ibm_botocore/credentials.py", line 2227, in _cleanup

AttributeError: 'Thread' object has no attribute 'isAlive'

Likely Cause

It seems that in Python 3.9.0 the isAlive method was renamed is_alive:

• webapp:az webapp create-remote-connection AttributeError: 'Thread' object has no attribute 'isAlive' Azure/azure-cli#15441 (comment)
• Python 3.9: AttributeError: 'Thread' object has no attribute 'isAlive' micheles/decorator#75

Thank you for your comment. We are aware of this change, which we are targeting for our next release.

This is a duplicate of IBM/ibm-cos-sdk-python-core#10.
