I’ll try that, but I just want to make clear that it’s the NICs that are failing to be gotten correctly. The GPUs work fine.

Hi, I know it’s been a while since I posted this but I wanted to update because this problem seems to have gotten worse (or maybe I’m just getting unlucky?) and I finally found the log file. I ran my slice setup and got this output in the notebook:

I checked the logs, and here’s what they say from the time I ran my code:

That worked! Thank you

[Xander Maddox Weintraut]

Yeah, here you go:

I don’t think so. I get a different error. I made sure that I didn’t have an opened slice called MySlice, then when I ran it I got this:

As you can see, the error is “Management IP Invalid: None” just after running post boot config. Does it also work for you if you try to run the script from Jupyter? That’s where I ran it from.

I haven’t gotten fabric to work properly from my local computer yet, I get this error, which I have a feeling might be because I’m trying to run it from Windows? I have no clue:

Failed to get slice topology: Status.FAILURE, Error [Unable to read graph C:\Users\xwein\AppData\Local\Temp\tmprkqs64qf-graphml] importing graph

Side note, how do I do the quote segment with overflow? I don’t know how to use this markup very well.

Let’s try this

[Xander Maddox Weintraut]

I don’t think I have permissions to upload files

• This reply was modified 2 years, 5 months ago by Xander Maddox Weintraut. Reason: Not allowed to upload .py files apparently. You'll have to resave this as a .py before you can run it
• This reply was modified 2 years, 5 months ago by Xander Maddox Weintraut. Reason: Can't upload files

[Xander Maddox Weintraut]

Right, that’s what I did.

First I made sure the “Hello, FABRIC notebook ran correctly.

Then I made a python script with all of the code cells copy/pasted directly back-to-back.

When I ran that script from the terminal, this was the output:

The Errors after the “Running post boot config…” line are because the submit() call throws an exception before it finishes, so the later calls are trying to act on a slice that is not stable yet.

The slice does eventually reach StableOK state, but it has no nodes.

I am not having any issues running the notebook. Only with running .py scripts

[Xander Maddox Weintraut]

I’m in ULTIMA. I don’t think we need any more tags at the moment, but will let you know as the need arises. However, all of the Networking examples after “Create a Local Ethernet (Layer 2)” require the Slice.Multisite tag to run.

Regardless, I’m fairly sure that permissions tags aren’t the issue here.

[Xander Maddox Weintraut]

The notebook runs just fine. The only notebooks that have failed have been ones that require project tags I don’t have.

[Xander Maddox Weintraut]

I just went through the list of sites, and was able to reproduce the issue with every site.
