Exporting Tensorflow models to Jetson Nano

Hi,

We are training different neural networks using Tensorflow Object Detection API on Tensorflow 1.15 and 2.3 with pretrained models. The whole process is running on the computer with Tesla GPU. After exporting the frozen inference graph, we are converting it to the UFF or ONNX format on computer with Tesla and then loading it into TensorRT on Jetson Nano. Unfortunatelly with UFF files we have config file only for SSD Mobilenet v2 and when we to load the ONNX graph to Jetson Nano, TensorRT says that it has unsupported data type (UINT8). We did not find any way to get the FP16, FP32 or INT8 precision, which would be supported on the Jetson.

My questions are (depending on the way we choose):

  1. frozen_inference_graph.pb -> UFF -> TensorRT
    Is there any actual tutorial/list of steps with apropriate config files on how to export the pretrained models into UFF
    files? For example for ResNet 50 or 101. Those are being parsed correctly by TensorRT on the Jetson Nano.
  2. frozen_inference_graph.pb -> ONNX -> TensorRT
    How can we get the proper precision (other than UINT8) that would be supported on Jetson Nano with TensorRT?

This is quite interesting!
Could you please tell me a bit about this idea…

I also have got two pb files, that I am just curious how to get to TRT format
Thanks

Hi,

There are some config.py example in the TensorRT sample folder:

/usr/src/tensorrt/samples/sampleUffFasterRCNN/config.py
/usr/src/tensorrt/samples/sampleUffMaskRCNN/converted/config.py
/usr/src/tensorrt/samples/sampleUffSSD/config.py

The interface to map a .pb model into .uff is called graphsurgeon.
You can find the detail document here:
https://docs.nvidia.com/deeplearning/tensorrt/api/python_api/graphsurgeon/graphsurgeon.html

For INT8 issue, please noticed that INT8 operation requires > 7.x GPU architecture.
Nano’s architecture is 5.3 which cannot support INT8 inference.

Thanks.

Ok, so Jetson Nano supports FP16 and FP32 only. But how to force that precision in the output ONNX model?

After exporting our trained model to frozen inference graph we are doing something like:

python3 -m tf2onnx.convert --saved-model model/saved_model/ --opset 11 --output model.onnx

And no matter what, we always get the UINT8 format, which is unsupported.

@AastaLLL
Thanks for replay.
Ok so now we use convert-to-uff
python3 convert-to-uff frozen_ssd_mobilenet.pb -O NMS -p config.py (/usr/src/tensorrt/samples/sampleUffSSD/config.py)

UPDATE
So we just try to run config.py from this post. It’s working for mobilenet_v2
https://forums.developer.nvidia.com/t/how-adapt-tensorflow-object-detection-for-custom-dataset-to-deepstream-5-0/145706/15?u=harryxdllll

Can you guide as what we should change in the config file to export ssd_resnet_50_fpn_coco?

Let me share log from convert_to_uff.py ( ssd_resnet_50_fpn_coco):

Hi, harryxdllll

The error indicates some non-supported operation (ex. Tile, Slice, …).
To run these operations with TensorRT, you will need to enable them as a plugin layer.

Please find the following document for the plugin implementation details:

Thanks.

Hi, Elviron

The root cause is onnx expects input image to be INT8 but TensorRT use Float32.
To solve this issue, you can modify the input data format of ONNX with our graphsurgeon API directly.

1. Install ONNX Graphsurgeon API

$ sudo apt-get install python3-pip libprotobuf-dev protobuf-compiler
$ git clone https://github.com/NVIDIA/TensorRT.git
$ cd TensorRT/tools/onnx-graphsurgeon/
$ make install

2. Modify your model

import onnx_graphsurgeon as gs
import onnx
import numpy as np

graph = gs.import_onnx(onnx.load("model.onnx"))
for inp in graph.inputs:
    inp.dtype = np.float32

onnx.save(gs.export_onnx(graph), "updated_model.onnx")

Thanks.

Thanks, it works! However, now we have another problem. We have onnx version 1.7.0 (1.6.0 gave the same results), tensorflow 1.15.3 and tf2onnx 1.6.3. On every our network (SSD_mobilenet_v2, SSD_inception_v2, SSD_resnet_50) we have the same error when trying to parse ONNX model to TRT engine by using detectNet from jetson-inference:

What can we do about it?

Hi,

Good to know it works now.

The second issue looks related to the output.
Would you mind to check the onnx model with trtexec and share the log with us?

/usr/src/tensorrt/bin/trtexec --onnx=[your/model] --verbose

Thanks.

Ok, I’m sending you the full log.

trtexec.log (569,7 KB)

I don’t like the line “[10/23/2020-09:00:53] [V] [TRT] ModelImporter.cpp:202: Adding network input: image_tensor:0 with dtype: float32, dimensions: (-1, -1, -1, 3)”, but can this be the cause? How can I put proper dimensions to the model?

Hi,

The model uses dynamic input, and it’s recommended to set it to fix if you don’t need it.
You can specify the dimension directly through the ONNX Graphsurgeon API shared above.

For example:

...
input = graph.inputs[0]
input.shape = [1, 3, 512, 512]
...

Thanks.

Hi @AastaLLL thank you for your help so far. I am followinf this issue thread and I am stuck at exactly the same place as @Elviron to create a tensorRT file from ONNX.

I picked up a tensorflow model .pb (object detection), turned into .onnx with

python3 -m tf2onnx.convert --saved-model /tmp/export/saved_model/ --output /tmp/export/saved_model/model.onnx --opset 11

applied the above graph surgeon patch on .onnx file to cast the input tensor to 32f and applied a fixed size.

However when I try to turn it into a tensorRT file withonnx2trt /tmp/export/saved_model/updated_model.onnx -o /tmp/export/saved_model/model.trt

I got:

[2020-10-27 11:19:46 WARNING] /opt/onnx-tensorrt/onnx2trt_utils.cpp:220: Your ONNX model has been generated with INT64 weights, while TensorRT does not natively support INT64. Attempting to cast down to INT32.

Any ideas how to get past this?
Thanks

Hi,

[2020-10-27 11:19:46 ERROR] INVALID_ARGUMENT: getPluginCreator could not find plugin NonMaxSuppression version 1

This indicates that the required NonMaxSuppression layer is not supported by the TensorRT currently.
You can find the TensorRT support matrix here and onnx2trt’s here.

To fix this, you can integrate the NonMaxSuppression implementation to our TensorRT plugin and add it to the ModelImporter.

Thanks.

Hi again @AastaLLL , thanks for reaching out. Would you advice to replicate the tf’s version of nms into tensorrt instead of using any of the existing nms plugins that tensorRT has already on https://github.com/NVIDIA/TensorRT/tree/master/plugin/nmsPlugin or https://github.com/NVIDIA/TensorRT/tree/master/plugin/batchedNMSPlugin ?
So for I’ve been unsucessful with the last idea. Do you have a clear example how to integrate a plugin via ModelImporter?

Thanks

Hi,

I think the NonMaxSuppression used in the TensorFlow is different from the batchedNMSPlugin in the TensorRT.
You will need to integrate the TensorFlow implementation to TensorRT plugin first.

If you want to use batchedNMSPlugin, you can add the support to onnx parser builtin_op_importers.cpp directly.
Please check InstanceNormalization implementation as an example:

Thanks.

Yeah that confirms also our findings, that batchedNMSPlugin is expecting tensors with different dimensions then the ones we have from parsed onnx model. Instead of the batchedNMSPlugin you think we can make this work via the NMSPlugin instead? (https://github.com/NVIDIA/TensorRT/tree/master/plugin/nmsPlugin)

@AastaLLL thanks for your advices! So we have to implement the NonMaxSuppression plugin by our own in order to start our models working.
Is this necessary for every model? If not, can you provide us some list of models which should work in this workflow (TensorFlow -> Frozen Graph -> ONNX -> TensorRT engine) without that kind of modifications?
If none of the models works, then it seems we will have to go the @bnascimento way.

Hi, both

Sorry for the late reply.
You can use the NMSPlugin for the TensorFlow NonMaxSuppression operation.

The TensorRT plugin is already implemented and merged in the default library.
But the mapping doesn’t be added into the onnx-tensorr parser and leads to a non-registered error.

As mentioned above, you can add the mapping for NMSPlugin <-> NonMaxSuppression in builtin_op_importers.cpp and rebuild the onnx parser.

Thanks.
