cibot: Thank you for posting issue #21. The person in charge will reply soon.

In your Ubuntu system, check /usr/lib/nnstreamer/filters
If there is no tensorflow plugin there, it means you need to install nnstreamer-tensorflow.
Anyway, it appears that we need to update the manual (we recently separated nnstreamer-{frameworks} from nnstreamer main packages) and the dependency declaration of nnstreamer-tensorflow is incorrect for Ubuntu.
In the meanwhile, you may force-install nnstreamer-tensorflow (tell dpkg or apt to ignore dependencies) if you have installed tensorflow already.

helloahn : When a corresponding NNFW / subplugin does not exist, it is FATAL to the pipeline. Please emit READABLE messages without the need for GST_DEBUG envvars.
Never mind. I got this; I just remembered that such messages should not be emitted at the moment of "NNFW", but when it fails to start.

@dseuss nnstreamer/nnstreamer#1205 is supposed to fix this; you'll be able to install nnstreamer-tensorflow from PPA after we merge that PR and launchpad.net accepts the updates.

@dseuss The fixes are submitted to PPA/launchpad. You will soon be able to PPA-install nnstremer-tensorflow, which will fix this issue. With #1207 @ nnstreamer, any similar issues will generate clear error messages to notify to install the missing extension.
Thank you for the report!

Thanks @myungjoo for your quick help. I have reinstalled the newest version from launchpad and still get the same error (with GST_DEBUG=1):

However, the "missing file" /usr/lib/nnstreamer/filters/libnnstreamer_filter_tensorflow.so exists. For easier debugging, I've recreated the environment in a Dockerfile if you would like to test it.

In your docker, it appears that python 2.7 is required. It is probably because tensorflow of this build requires python 2.7. I, right now, don't sure why such dependencies are missing from packages. Normally, dependencies of shared obejcts are automatically resolved by packager (pdebuild).
