Could not run custom TFLite models on RB5 with GStreamer framework.

[veeramallirajesh]

I was following the GStreamer TFLite object detection and segmentation examples on the repo. I could run them on RB5. But, when I try to run my own TFLite segmentation model on it the inference is not working. I tried to debug the "qtimletflite" element and what I found from it is the error "MLE init failed." When I include "org.codeaurora.mle.tflite" in the config file for qtimletflite element I get the following debug message. I would like to know if there are any limitations on how a TFLite model should be developed and compiled.

Thank you.
