5 years ago Hi, I'd like to give you some hints which helped me to get it running:
1) add import batchspawner in your config file
2) you can look at the job logs to find out more about the problem (seems like your job does not connect to jupyterhub)

debug_log.txt jupyterhub_config.txt pbs_setup.txt
Trying a set up where we would have JupyterHub configured on host XX.XX.XX.XX and want to use batchspawner to spawn single user notebooks on host YY.YY.YY.YY But the spawn is failing with below error and hence unable to progress. jupyterhub_config.py file and the execution log generated by executing jupyterhub with --debug has been uploaded here.
Please guide as it seems I'm doing something fundamentally wrong here!

Also, there is no clear documentation available to set this up, so if this can kindly be looked at or if someone can kindly share any guide to implement this set-up that will be really helpful.
