APIC Sandbox Environment Setup error

[hoylandpaul]

Trying to setup my environment for the Intro to ACI programmability (https://developer.cisco.com/learning/lab/sbx-intro-aci-02_programmability-options/step/1) and followed all the steps successfully until I tried to follow the step:-

(venv) apic_fabric_setup\ $ python baseline.py

and got the following error:-

Baselining APIC Simulator for Learning Labs
Setting up Fabric Nodes
Traceback (most recent call last):
  File "baseline.py", line 11, in <module>
    import startup_script
  File "/home/paul/Documents/Study/devnet_ll/code/aci-learning-labs-code-samples/apic_fabric_setup/startup_script.py", line 42, in <module>

    self.__configMos[mo.dn] = mo
AttributeError: 'NoneType' object has no attribute 'dn'

Any ideas what is going on?

Have you followed the ..  How To Setup Your Own Computer 

[hoylandpaul]

Yes, all the steps completed without error.

[omz]

I have followed the same steps and get the same error. 

It looks like the cobra files are missing on the apic simulator.

https://sandboxapicdc.cisco.com/cobra/_downloads/

returns 403,404

Try this:

acicobra-3.0_1k-py2.7.egg —> https://developer.cisco.com/fileMedia/download/39308f27-4956-4bd8-8127-d0fac29158c4

I get the following errors when I try to `pip install` those modules:-

I get the same error

acicobra-3.0_1k-py2.7.egg

are these not for apic v3 and python2.7? or it doesn't matter?

apic simulator https://sandboxapicdc.cisco.com/

is on v4 and devnet lab is using Python 3

thanks

These are more current and the ones referenced in the learning lab ACI Programmability Options

For setting up your own environment, follow the set up (How To Setup Your Own Computer) of learning lab - https://developer.cisco.com/learning/lab/sbx-intro-aci-02_programmability-options/step/1

 

[omz]

yep completed step 1 - setup your own computer 

although the guide tells you use -  python setup.py install - after downloading acitoolkit from git .. 

it doesn't complete the setup

error: The 'flask' distribution was not found and is required by flask-wtf, acitoolkit, flask-httpauth

unless you do - pip install -r requirements.txt under acitoolkit. After this acitoolkit setup completes successfully.

and 4.2 .whl files installed successfully.

The issue is with 

startup_script.py for baseline .. adding MO .. c.addMo(topMo)

As this isn't a sandbox issue, I would suggest posting this in the support room where the learning lab/code can help triage your issue https://developer.cisco.com/site/spark-chat/ - sadly this goes beyond my knowledge of this area.

[omz]

It should work now .. just tested .. 

$ ./baseline.py
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

@bigevilbeard thanks a lot for directing to the WebEx Teams room. 

There was another issue where no changes were being made on the apic.  

Both issues got resolved by resetting the sandbox. 

[bigevilbeard]

Thanks for the update, i saw Hank jumped in. I was chatting with our ENG support team, as I saw another two threads having an issue with the same sandbox.

[hoylandpaul]

Thanks, I can confirm that it is now working :0)
