Certbot throws TypeError

I'm a little stumped here. I've never seen an error from inspect.py before, but here I am trying to install some SSL certificates with certbot and an error occurs. The certbot log including the stack trace is here, but the error is:

  File "/usr/lib64/python2.7/inspect.py", line 815, in getargspec
    raise TypeError('{!r} is not a Python function'.format(func)) 
TypeError: <method-wrapper '__ne__' of type object at 0x1eeab80> is not a Python function

And occurs when running certbot certonly. Other commands, such as retrieving the version, are fine.

I've tried a few things (uninstalling/reinstalling, etc) but to no avail. I'm trying to avoid installing from git or some other source (trying to stick with yum). Some more details

What's strange is this error seems to indicate an error in implementation, but I find this strange, since I'm using certbot on another CentOS 7 machine without issue.

Any help is greatly appreciated. I will open an issue on GitHub if appropriate, but figured I would ask here first.

You need update cryptography with: pip2 install -U cryptography

and maybe pyOpenSSL: pip2 install -U pyOpenSSL

You can use one command to check all requirements: pip2 install -U certbot
