Hello - this repository is for the Boto3 AWS SDK for Python. I didn't see any references to boto3 in your logs or Dockerfile. The RuntimeError: can't start new thread has been reported several times in other places. I saw a few different solutions mentioned such as upgrading Docker or adding --progress-bar off to your pip install command. Since this issue doesn't appear to involve boto3 I'm going to close it.
