platform:
linux16.04
K2200
cuda10.0
cudnn7.6.5
python 3.6
tensorflow 1.12
tensorrt 6.0.1

problem:
By using the code “https://github.com/AastaNV/TRT_object_detection
Set “from config import model_ssd_mobilenet_v2_coco_2018_03_29 as model”
using the official model from “https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/detection_model_zoo.md”, model is “ssd_mobilenet_v2_coco”. it gets right result.
But using the above model to retrain the model under our data, get a frozen model;
By using the frozen model, got the following error:
python3 main.py …/image1.jpg

model file is at: “https://drive.google.com/file/d/1e-9cb_sLmuevA4h1IPP029vUH3IxlIx1/view?usp=sharing

can you test my pb file ?

Thanks.

Hi,

You may need to update the configure file for your model, eg. input dimension or class.

Please refer to below example:
https://github.com/AastaNV/TRT_object_detection/blob/master/config/model_ssd_mobilenet_v2_coco_2018_03_29.py

Thanks

Hi,

I met this issue and this is the way I solve it.

This issue is possible come from this parameter “numClasses” in “NMS create plugin node”.

As I know so far, parameter numClasses = “your num_classes” + 1. The plus 1 is for background class.

https://devtalk.nvidia.com/default/topic/1069027/tensorrt/parsing-gridanchor-op-gridanchor_trt-protobuf-repeated_field-h-1408-check-failed-index-lt-current_size-/?offset=3#5415537

I meet same issue and my model is ssd_mobilenet_v1, the parameter “numClasses” in "NMS create plugin node has changed to “my num_classes” + 1, and the error not solved.
