[tizen_iot_text_classification] libnnstreamer_protobuf.so: cannot open shared object file: No such file or directory.

[tony-jinwoo-ahn]

hello, I've built nnstreamer_tizen_iot_text_classification for ubuntu 18.04 on "RaspberryPi4B" and ubuntu 18.04 on "laptop".
I've tested using Rpi4/PC for server/client and vice versa, and got error:

$ ./nnstreamer_tizen_iot_text_classification server tensorflow-lite $MYIP $MYPORT

** (nnstreamer_tizen_iot_text_classification:4824): CRITICAL **: 23:57:48.203: Cannot open protobuf(/usr/lib/nnstreamer/decoders/libnnstreamer_decoder_protobuf.so) with error libnnstreamer_protobuf.so: cannot open shared object file: No such file or directory.

(nnstreamer_tizen_iot_text_classification:4824): GStreamer-CRITICAL **: 23:57:48.208: gst_mini_object_unref: assertion 'mini_object != NULL' failed

... and error chain...

I have a question: what package should I install exactly?
I've installed:

sudo apt install libprotobuf-dev 
sudo apt install libprotobuf-c-dev

but seems not the answer.

Thank you.

I've checked library installed already, and became root and tried again, but same error.

libnnstreamer_decoder_protobuf.so already exists... I cannot figure out now.

Hello, @tony-jinwoo-ahn

1. tizen_iot_text_classification operates on tizenIoT platform. If you want to use this app, you have to install tizenIoT platform image on your RPI4.

2. try to install libprotobuf17

Thank you, @gichan-jang
I installed those you suggested on my Rpi and PC, but still same error.
anyway, thank you for your comment.

@tony-jinwoo-ahn
You need to install nnstreamer-protobuf
But there is conflict between nnstreamer and nnstreamer-protobuf. I will fix it.

[tony-jinwoo-ahn]

thank you. I would try sudo apt install nnstreamer-protobuf after the conflict is fixed.

[gichan-jang]

@tony-jinwoo-ahn
nnstreamer-protobuf package conflict has been resolved.

[tony-jinwoo-ahn]

thank you!! 👍

I tested and it's fixed OK.
I don't need to do "sudo apt install nnstreamer-protobuf".
I re-installed nnstreamer and it works OK.
