I'm trying to automatically start jupyter server on boot. (ec2, amazon linux)

I got the jupyter server working and correctly loading all the conda kernels.

and I tried to run jupyter on boot. (tried rc.local, systemd, crontab and all fails to load conda kernels and only loads basic python2 and python3 kernels)

I've traced it down to the nb\_conda\_kernels not finding being able to call 'conda' on boot, as below:

```

Oct 30 01:07:40 ip-172-31-17-102 rc.local: [I 01:07:40.061 NotebookApp] The Jupyter Notebook is running at:

```

The weirdest thing is that when I kill the running server with "sudo ss --tulpn | grep 8888" (to find pid for jupyter notebook which is listening on port 8888) and "sudo kill -9 {pid}" (to kill the process. checked that I killed it successfully), and I restart the server via the same command used in boot, then jupyter successfully loads the conda kernels, as below:

```

```

I've seen one particular question on stackoverflow about this issue. ([Jupyter notebook can't find kernel when run through /etc/rc.local](https://stackoverflow.com/questions/35723309/jupyter-notebook-cant-find-kernel-when-run-through-etc-rc-local))
but the issue here is that when I type "jupyter kernelspec list", I only get python3 and python2, even when jupyter has already loaded conda kernels successfully.

```
python3    /home/ec2-user/anaconda3/share/jupyter/kernels/python3
  python2    /usr/share/jupyter/kernels/python2

```

Also, I've tried changing environmentspecmanager in jupyter config file to see if it solves the issue but it didn't. (same error log, "couldn't call conda")

what is the problem here?
