After starting HTM engine using `supervisord -c ~/numenta-apps/taurus_engine/conf-user/supervisord.conf --logfile /tmp/htm.log --loglevel info`, I’m seeing this error in the taurus\_metric\_collectors log in HTM Engine.

Traceback (most recent call last):

AttributeError: ‘module’ object has no attribute ‘PROTOCOL\_SSLv3’

From what I read on [StackOverflow](http://stackoverflow.com/questions/28987891/patch-pyopenssl-for-sslv3-issue), it seems to be an issue with urllib3, no with pyopenssl.  
I fixed it by upgrading `pip install requests==2.6.0`. But after doing so, I attempted to `taurus-reset-collectorsdb`, and that threw a similar error stating requests v2.0.1 is required.

I then uninstalled the requests package, and re-installed using `pip install requests==2.0.1`.

With version 2.0.1 installed, `taurus-reset-collectorsdb` ran without error. But now I’m getting the first error again.

It seems I’m caught chasing myself around the mulberry bush, so to speak. It seems like a versioning issue. Just now I was going to try installing the very next version higher than 2.0.1, with the hope one of the versions in between 2.0.1 and 2.6.0 might avoid both errors. But, on PyPi, the release history for the `requests` package only shows back to 2.10.0.

It seems I’m a bit stuck. Anyone have any suggestions?

I just uninstalled requests and re-installed `pip install requests==2.2.1` and that seems to have done the trick.
