subgraph conversion error for subgraph_index:0

[geonseoks]

Hello?
I convert detection.ipynb file to detection.py and test it.
But subgraph conversion error occur and there are no detection results.

I use JetPACK-3.2.1 and tensorflow1.8.0(python3)
I don't know what wrong..
Can you help me with this error?

The reported error is actually a warning. In this instance, engine creation for one of the discovered sub-graphs failed so tensorrt integration fell back to the original tensorflow sub-graph. However, for the other sub-graph, engine creation succeeded (my_trt_op1) which contains 434 nodes.

Hello?
I have the same problem
When I followed the test all of the ssd models, I was given an error.

subgraph conversion error for subgraph_index:0 due to: "Unimplemented: Require 4 dimensional input. Got 1 Postprocessor/BatchMultiClassNonMaxSuppression/MultiClassNonMaxSuppression/zeros_like_30" SKIPPING......( 181 nodes) subgraph conversion error for subgraph_index:0

I can't get the trt model.
I don't know what wrong..
Can you help me with this error?
thank you very much
