After the installation of SAS Studio with JupterLab in my computer, I had several runs with SASPy, which went well, and I got desired output. Now my further attempts to invoke Python 3 using JupyterLab are failing. I am getting this error - "Invalid response: 500 Internal Server Error".
Any help toward the resolution of the issue would be appreciated.
Thank you so much for responding to my query.
It was just yesterday (12/19/2018) that I updated the installations based on this: download the newest SAS University Edition vApp from our website, and remove/re-import the SAS University Edition Virtual Machine into Oracle VirtualBox or VMware Workstation with additional instructions I received on the same day from SAS Institute.
This morning, the technical support person at SAS Institute has suggested to me that I post this question (Internal Server Error) here.
Any further guidance toward resolving the issue would be appreciated.
I don't. But try restarting and try a different browser. And make sure any browser extensions are turned off if you're using them.
I have recollections of getting this error and it then went away on it's own. Have you tried the good ol' power everything down and start up again? Assuming you have, I'm not sure. I'll check mine tonight to see if I can get on using SAS UE.
Just to confirm one more time though, you're using Jupyter that comes up when SAS UE pops up and instead of clicking Studio your Jupyter notebook never opens.
Just wanted to confirm to you that the VM (in black screen) was running. Do you think that is an installation issue? Thanks,
Hey, so do I have it right that you updated, but really that downloads the new image and you removed the previous UE and installed this one into virtual box outright? So there's no real update the parts inside the VM; it's a clean install? I have only limited experience with UE, and I haven't gone through the Update process, just install.
You mentioned that at first this worked fine. Do you know 'what changed' between when it worked and quit working?
I googled 'jupyter lab Invalid response: 500 Internal Server Error' and there are a lot of hits. Some of these have to do with mismatched versions of various jupyter components or configuration, while others are about a specific notebook not working - perhaps corrupted.
For your situation, is it a particular notebook? If you try to reinstall the VM will it start working again? I just downloaded and installed this and, of course, it worked fine; as you experienced. I don't know what to do to try to see if I can reproduce this. Any more specifics about your scenario?
Ah, after entering this, I saw a set of links to the side of this issue showing 'related topics'. One of those was similar to this, and it appears to have this problem figured out and addressed! See this entry: https://communities.sas.com/t5/SAS-Analytics-U/SAS-University-Edition-JupyterLab-Error-Message-quot-...
It had to do with saving the state of the VM as opposed to shutting it down. Sounds like it resolves this. See if it does for your case.
