1.58 introduces a dependency on multiprocessing.RLock which it not compatible with AWS Lambda. multiprocessing.SemLock (used by RLock in Requester.py) will raise OSError [Errno 38] Function not implemented. This is caused by /dev/shm not being available in AWS Lamba.

I don't have a workaround and downgraded to 1.57 which works fine.
