Failed to run TfCnn example from User Guide: ERROR find objects: parse jsonnet snippet: params.libsonnet:22:5-13 Expected a comma before next field.

I am getting an error when I try to run the TfCnn example from the User Guide:
The docs say to run:

CNN_JOB_NAME=mycnnjob
ks generate tf-cnn ${CNN_JOB_NAME} --name=${CNN_JOB_NAME}
ks apply ${KF_ENV} -c ${CNN_JOB_NAME}

I get the error:
ERROR find objects: parse jsonnet snippet: params.libsonnet:22:5-13 Expected a comma before next field.

When I looked at components/params.libsonnet, I see it has added a 'mycynnjob' stanza after the components stanza, but it omits the comma between the two components:

components: {
// Component-level parameters, defined initially from 'ks prototype use ...'
// Each object below should correspond to a component in the components/ directory
....
} /// THERE NEEDS TO BE A TRAILING COMMA HERE
mycnnjob: {
batch_size: 32,
....
}

I'm not sure why this is happening, I guess it is some sort of issue with 'ks generate'?

• What version of ksonnet are you using?
• What version of kubeflow are you using?

ks version 0.10.2 and kubeflow version v0.1.2 seems to work for me

Per @ankushagarwal 's comment components/params.libsonnet is generated by ks not us so its most likely something with ks.

Yep, I think what's happened is that I downloaded the 'ks' binary from the ksonnet site, and it embeds versions of those files, then blindly updates them without respecting syntax.

Closing because it's not kubeflow-specific.
