What is the appropriate syntax to define EvaluationNodes in CNTK Brainscript -


using brainscript in cntk 2.1 define basic network, appropriate way define multiple evaluation nodes?

i have created custom functions , wish use them collectively / simultaneously when use comma separated list per https://docs.microsoft.com/en-us/cognitive-toolkit/special-nodes encounter following error

[call stack]                 evalnodes = (ce, te, tm)                    ^ exception occurred. while parsing: brainscriptnetworkbuilder(27): ')' expected

when trying "tag" approach encounter following error

                ce = classificationerror (labels, out.z, tag=eval)                                                  ^ exception occurred. while evaluating: brainscriptnetworkbuilder(21): unknown identifier 'eval'

undoubtedly issue pebkac although i'd appreciate pointer or 2 on correct way achieve outcome.

brainscript case sensitive. please change evalnodes evalnodes. tag in classificationerror, please use string tag: 

ce = classificationerror(labels, out.z, tag='eval')
