gst-inference 做出错误的推断

问题描述

我在基于 arm64 的 ubuntu18.04 板上安装了 gststreamer+gstinference+r2inference+tensorflow-lite。 一切顺利，直到我开始使用 gst-launch cmd 推断图像。

IMAGE_FILE=/home/pi/cat.jpg
LABELS='labels.txt'
MODEL_LOCATION='graph_inceptionv2.tflite'
GST_DEBUG=inceptionv2:6 gst-launch-1.0 \
multifilesrc location=$IMAGE_FILE start-index=0 stop-index=0 loop=false  ! jpegparse ! jpegdec ! videoconvert ! videoscale ! videorate ! queue ! jpegenc ! filesink location=capture1.jpeg

Which gave out a result of:

--------------------------------------
Said it was koala bear,But this is a 224*224 egytian cat images which was correctly inferenced by R2inference sample program.

我的 Gst-inference 和 R2Inference 配置之间有什么问题？？请帮忙。
