PX2 tensorRT optimization tool Error


I got this error when I tried to optimize the uff model on PX2 using the tensorRT_optimization tool in the driveworks-0.6. Could you give me some possible reasons about this error?

sudo ./tensorRT_optimization --modelType=uff --inputBlobs=input_1 --inputDims=224x224x3 --outputBlobs=predictions/Softmax --uffFile=../data/samples/detector/testmodel.uff --out=~/Desktop/test.bin

Dear zhisheng,
The tensorRT optimization tool supports caffe models in driveworks 0.6. Please refer /usr/local/driveworks-0.6/doc/nvdwx_html/dwx_tensorRT_tool.html
