@shaliniGovindaNayak @pradyuz3rocool Have you completed the pre-req's as documented ? https://tibcosoftware.github.io/flogo/development/flows/tensorflow/getting-started/

Umm ... just started to read the Tensorflow doc ... not sure it's supported on RPi

@abramvandergeest Does the TF integration work with RPI ?

Reading more .. it looks like you can build it for RPI ... but you have to do a full build .... https://www.tensorflow.org/install/source_rpi

Abram Van Der Geest

@abramvandergeest

@mellistibco has built an ML app for RPi before so it should work. the only complication is that you need to have the tensorflow dynamic libs installed on the Pi

Pradyumna Chakicherla

@pradyuz3rocool

@mellistibco - Hi , what was the version of tensorflow you instaled on the raspberry PI?

THanks @abramvandergeest

Abram Van Der Geest

@abramvandergeest

this was a fairly old version of TF 1.3 I think

Pradyumna Chakicherla

@pradyuz3rocool

so the ml inferencing activity supports the latest 1.9 version of tf?

imts the latest version on the project-flogo/ml ?

Abram Van Der Geest

@abramvandergeest

project-flogo/ml has been run with TF 1.12, I haven't tested it with 1.13 (should work) or 2.0alpha (in alpha testing, and I don't expect it to work, this is a future project)

Pradyumna Chakicherla

@pradyuz3rocool

OK sure @abramvandergeest thanks

I need someone to review and merge project-flogo/core#111 it is needed for a TIBCO Now demo; thanks

@fm-tibco

Andrew, I’ve been out of commission these past few days from wisdom teeth extraction... I asked Tracy and Samip to review it.. if you need anything else today or tomorrow reach out to them

Matt is also on vacation, he’ll be back this weekend

Thanks!

Hi .. I there any way to implement enterprise flogo mapper activity into docker flogo .. coz the docker flogo mapper activity is not able to take the inputs to map

Do we know how to subscribe a message from Solace Queue/Topic ? Tried with REST invoke get method but got only Queue/Topic properties but not body. Also verified with MQTT Topic Subscriber but I could not see any subscriber count on the topic... Any Pointers ??

Mark Mussett

@mmussett

@hari-kasetty Shouldn’t be difficult to write a trigger for PubSub+

hari-kasetty

@hari-kasetty

Thanks Mark. Could you please give some reference to write a trigger for Subscribing message from Solace ?

Samip Kothari

@skothari-tibco

@dhire05 I think coerce.toParams should do it. Also there’s no straightforward way to have enterprise contributions on OSS logo.

Leon Stigter

@retgits

@hari-kasetty if you want to connect using the Mqtt protocol you can use the existing trigger that @jvanderl has written... if you want to connect using the native Solace protocols you’ll have to ask the Solace team to build a Go SDK

@alexandrev

Hi team, I'm building a Prometheus Pusher activity and everything is working fine in local when I do the tests and so on, but when I use it inside my app, I'm getting these kind of errors

2019/06/08 22:36:03 proto: duplicate proto type registered: io.prometheus.client.Bucket
2019/06/08 22:36:03 proto: duplicate proto type registered: io.prometheus.client.Metric
2019/06/08 22:36:03 proto: duplicate proto type registered: io.prometheus.client.MetricFamily
panic: proto: duplicate enum registered: io.prometheus.client.MetricType

I'm only importing the packages in my activity.go, nothing else...

any hints?

Mark Mussett

@mmussett

@alexandrev There’s already a statsd activity that works with Prometheus and Grafana on the showcase that i wrote.

hari-kasetty

@hari-kasetty

@retgits Thank you for your response. When connected using MQTT Protocol , I could not see any subscriber count on the topic and also messages are not flowing ... Do we need to check anything in MQTT or any specific settings. Any pointers please ..

Alexandre Vazquez

@alexandrev

@mmussett that a lot, but that requires an statd daemon running right? and then using Prometheus Exporter for statsd? Or am I missing something?

Andy Hampshire

@ayh20

@alexandrev That sounds like a Golang issue ..... if you search for "proto: duplicate proto type registered" there are a number of hits that describe situation where there is some form of name collision with different packages ... my go skills arn't enough to help you any further....

Alexandre Vazquez

@alexandrev

@ayh20 yep, the problem seems to be a colission with the embedded Prometheyus integration in FE 2.6

I'll try in OSS and see if it is working fine there

Andy Hampshire

@ayh20

@hari-kasetty What do you see if you turn on DEBUG ? Do you see connection information when Flogo connects to MQTT ? Have you tried emulating your connection details with a tool like MQTT.fx ? Have you tried a different MQTT server like Mosquitto to eliminate that the problem is with the server ? I've used MQTT quite a bit and the only issues i've ever had are due to me not getting the right url or topic name patterns

Massimo Bestazza

@mbestazza

Hi all does anyone try to run flogo on espressif 32?

hari-kasetty

@hari-kasetty

@ayh20 . Thank you so much Andy for your inputs. In Solace, I don't see any option to turn on DEBUG mode. I tried using MQTT.fx tool that is mentioned. Able to see Client ID in MQTT Sessions. But in the MQTT.fx console, "session present: false". Could you please let me know if I am missing something here.

Andy Hampshire

@ayh20

@hari-kasetty i was thinking of DEBUG for the FLOGO_lOG_LEVEL ... what messages does the trigger generate when it tries to connect.
If you can't get MQTT.fx to connect then i suspect that the problem is at the Solace end..... you need a Solace expert i guess

hari-kasetty

@hari-kasetty

Thank you for quick reply. It is showing below log in Flogo when I used MQTT Topic Subscriber which does not have errors.

Andy Hampshire

@ayh20

Turn on DEBUG and what other messages do you get ?
Do you know Solace provides a fully compliant version of MQTT ? If MQTT.fx doesn't work either then i don't think Flogo is your problem

Samip Kothari

@skothari-tibco

@hari-kasetty a while back we had some issues reading from mqtt broker using paho.mqtt.golang library (which flogo trigger uses to connect to mqtt) version v1.2.0 . However we were able to read using v1.1.1 . I would suggest creating a sample Go program and test out which version is able to connect and read .

hari-kasetty

@hari-kasetty

Thank you Andy and Samip for sharing valuable inputs. I will look into it and will see if I get any connection to Solace using MQTT. Thanks Again !!!

Alexandre Vazquez

@alexandrev

do we have something like an if;then;else function to use inside the mappings?

Mark Mussett

@mmussett

@alexandrev i use a graphite/grafana container. Works a treat for time series data

Alexandre Vazquez

@alexandrev

thanks @mmussett I'll take a look at another option instead of using Prometheus!

Mark Mussett

@mmussett

@mbestazza RPI is still the best device to show off flogo on
