I am working currently with the Zoo Models from Tensorflow. More specific the Mobilenetv1 + SSD for Object detection. I have no issues so far using the standard pipeline and convert it using the model optimizer. I am also able to run it on the samples provided by OpenVino.
However, my issue is when I changed score_converter: SOFTMAX instead of score_converter: SIGMOID in my model's pipeline. The conversion goes smoothly but when I try it the sample the results are completely different from the tensorflow's PB that I am using. It seems I that all the confidence scores I receive are 1. I tried looking into the ObjectDetectionAPISSDPostprocessorReplacement class, but I am being overwhelmed. Any suggestions?
This happened to me on R3 and it still happens to me on R4.
After investing some hours into this I was able to find where is the issue but I could not figure out why.
I just changed this line of code
if activation_function == 'SOFTMAX': # softmax to be applied to the confidence softmax_conf_op = Softmax(graph, dict(axis=3, nchw_layout=True)) activation_node = softmax_conf_op.create_node([node], dict(name=node.name + '/softmax'))
Changing the axis from 1 to 3 made my network work on the Object_detection_sample_ssd.
Anyone knows what could be the issue?
