Sandbox Learning Labs issue - ACI Programmability Options

c1sc0d1sc0 — Tue, 04 Jun 2019 16:32:43 GMT

Hi all,

I'm stuck with a problem on ACI Programmability Options lab, section APIC Sandbox Environment Setup, it says:

# From within the correct virtual environment (venv) apic_fabric_setup\ $ python baseline.py

# Expected Output

Baselining APIC Simulator for Learning Labs

Setting up Fabric Nodes

Configuring Fabric Policies

Setting up Common Tenant

Setting up Heroes Tenant

Setting up SnV Tenant

But my output is:

(venv) C:\Python27\aci-learning-labs-code-samples\apic_fabric_setup>baseline.py

Baselining APIC Simulator for Learning Labs

Setting up Fabric Nodes

Configuring Fabric Policies

Any ideas what I may have done wrong?

Thanks,

Can you please provide the link of the learning lab content you are following and the link to the sample code repo where you cloned the sample code ?

Thanks,

Yawming

Hi,

Its this lab:

Cisco DevNet Learning Labs

And I followed the instructions - How To Setup Your Own Computer at the top of the page.

I just went followed steps on Windows and worked for me.

Can you try it again and if not worked please list all the steps you went through.

I have the same exact problem, here are the steps I took before encountering the error during the baseline.py run, last part of "how to set up your computer" that I followed was to install the acicobra/ acimodel .eggs which worked fine per pip freeze:

I had the same problem on my Mac and gave up on it last night. I got back from work this morning and tried again before my Mac established internet access and it worked. I don't know if that helps anyone but decided to share incase someone wants to try it.

If it's any help to someone, I ran into a this issue as well. Output below:

cobra.mit.request.CommitError: Validation failed: Validation failed for node: 101Overlapping interfaces. Last examined: uni/infra/accportprof-Switch101-102_Profile_ifselector

My solution was to go to the APIC GUI -> Fabric -> Access Policies -> Interfaces -> Leaf Interfaces -> Profiles and delete the entry related to the last line of my error output (I think it was just Switch101-102). The baseline script worked after that. The thing is I broke a lot of stuff in the APIC before I found that setting so it should be interesting to see how my lab works now, but it was fun 🙂

i saw your comment but it was hard to believe that it will work, still i tried to run again and it worked when i run after 10 hours even i didn't make any changes to make it possible.
