I am trying to use a simple Elasticsearch client in python using AWS (ssh'd on an Amazon linux e3 machine). The code I am copying is here . I am unable to import the Elasticsearch class as described in the guide.

Using from elasticsearch import Elasticsearch gives me the error: ImportError: cannot import name 'Elasticsearch' .

I opened the python3 cli to check it out. If I type from elasticsearch import E and tab-complete, I get the following suggestions: EOFError( Ellipsis EnvironmentError( Exception( . However from elasticsearch import Ellipsis gives me ImportError: cannot import name 'Ellipsis' .

If I type import elasticsearch , then on the next line elasticsearch. and hit tab to autocomplete, I get the full range that I would expect ( Elasticsearch( , RequestsHttpConnection( , etc.).

I assume that this has something to do with the way/where it is installed.

I used pip3 install elasticsearch --user to install it originally. I uninstalled it ( pip3 uninstall elasticsearch ) and returned to the python cli. from elasticsearch import E still gives me EOFError( Ellipsis EnvironmentError( Exception( on the tab-complete, but from elasticsearch import Ellipsis now returns ModuleNotFoundError: No module named 'elasticsearch' , as does just import elasticsearch .

Not really quite sure what is up. I did not tag this as elasticsearch because it might be a user error :P

• which python3 : /usr/bin/python3
• which pip3 : ~/.local/bin/pip3
• pip3 --version : pip 18.1 from /home/ec2-user/.local/lib/python3.6/site-packages/pip (python 3.6)

My problem was that I had named my file the same thing as the module I was trying to import from - elasticsearch.py . As user2357112 states, I became hung up on the incorrect autocomplete.
