Authenticator class cannot be imported

[vishma]

I have tried to use ldap authenticator with jupyterhub 0.9.6.

I have added this to my jupyterhub config file.

c.JupyterHub.authenticator_class = 'ldapauthenticator.LDAPAuthenticator'

I am getting the following error. However I can import LDAPAuthenticator class from a python script therefore I assume ldapauthenticator has installed correctly.

Any help would be appreciated.
Thanks !!!

Sounds like you're running jupyterhub from a different python environment than the one you tested in. ldapauthenticator will have to be installed in the environment which jupyterhub runs in

You are correct. Turns out when I use sudo jupyterhub cmd to start the server it uses the system-wide default python installation instead of my conda virtual environment.

Thanks for the reply.
