Migrated from DeepStream 4 to Deepstream 5 and got errors

Hello, any help? Please.

Hello. Have set rtsp cameras quantity to 4, also batch-size of all CNN were up to 4, so right now ONNX model, even with force-implicit-batch-dim=0 are not compiling into TRT engine. Same error.


Sorry for the late update.

May I know which model format do you use first? Is it caffemodel or onnx?
It’s recommended to run you model with trtexec binary to see if the issue comes from TensorRT first.

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


Hello, AastaLLL.
I do use resnet50-caffe2-v1-9.onnx. Thanks for advise, will try it.

Hello. Have tested like you have written. Also got from another thread --saveEngine function.

TensorRT got passed over resnet50 ONNX, with batchsize of 4.

But, when i try to compile engine file with deepstream - it is fails. Just like in this message Preprocessing between pgie and sgie

But even if i set --maxBatch=4 and compile engine i got this:

And this

ERROR: [TRT]: …/builder/cudnnBuilderBlockChooser.cpp (117) - Assertion Error in buildMemGraph: 0 (mg.nodes[mg.regionIndices[outputRegion]].size == mg.nodes[mg.regionIndices[inputRegion]].size)

ERROR: failed to build trt engine.

Small update: i removed batch check, set all to 1 and it does it’s job.
But still falls down with same error.

Hello, again :-)

I got culprit of my error, it is image getting from NvBuf. When i remove it - program works until i shut it down. So i got recoded using of it, basically make OpenCV to release all buffer images, used for conversion from NvBuf to OCR code.

But now i am facing more errors! Will make new thread for it.


Sorry for the late update and thanks for the detail update.

It seems that the model can run correctly with TensorRT separately.
Would you mind to share a reproducible source with us so we can check it for you?


Hello, thank for reply.
No, i have found MAIN error, right now i need to find better way to save images from NvBuf into OpenCV Mat, or just save images into jpeg/png/bmp files. Yes i have checked deepstream-test5-sample, but adaptating it’s code gives me nothing, but i will try it again.
All this because NvBuf and CPU share same RAM and sometimes there is bug that can overwrite into wrong sectors.
I have pasted my code for saving images, main part of which i got from this forum :-)

Please help with another bug, with NvTracker initial ID value , i have already made new thread.
Thank you,


So is the original cudnn error solved?
Just want to confirm it.


Original issue, which is ONNX on DP5, partially resolved. Because with batch-size=1 DP5 can make and use engine by itself. But with batch size bigger than 1 - it crashes. And i can make engine with batch-size>1 with TRT, but DP5, when loading it, issue error described in Migrated from DeepStream 4 to Deepstream 5 and got errors
So i can use ONLY batch size of 1 with ONNX models.

Because of all this, problem is partially solved.


Have you re-generate the engine file?
It is possible that Deepstream use the exist engine file which created with batchsize=1 and causes this error.


Yes, it is re-generated. Problem is in batch-size > 1, batch-size=1 is working OK. And i do re-generate it in DP5.

Best regards.

I am sure that there will be solution to DP5 + ONNX with batch size > 1.
You can close this thread.

Best regards.


Not sure which solution do you find.
Here is our suggestion for your reference.

Assertion Error in buildMemGraph: 0 (mg.nodes[mg.regionIndices[outputRegion]].size == mg.nodes[mg.regionIndices[inputRegion]].size)

Based on above log, the error occurs from an onnx model doesn’t generate with the correct batchsize.
Since you try to use batchsize=2, the model need to be generated with batchsize 2 or dynamic batchsize.

We can reproduce this error with our /usr/src/tensorrt/data/resnet50/ResNet50.onnx model.
To solve this issue, we re-generate the onnx file for batchsize==2.
This can be achieved via our ONNX GraphSurgeon API:

1. Install

$ https://github.com/NVIDIA/TensorRT.git
$ cd TensorRT/tools/onnx-graphsurgeon/
$ make install

2. Generate your own convert.py.
Here is our sample for resnet50.
In general, we change the input batch, output batch and the reshape operation right before the output layer.

import onnx_graphsurgeon as gs
import onnx

batch = 2

graph = gs.import_onnx(onnx.load("ResNet50.onnx"))
for inp in graph.inputs:
    inp.shape[0] = batch
for out in graph.outputs:
    out.shape[0] = batch

# update reshape from [1, 2048] to [2, 2048]
reshape = [node for node in graph.nodes if node.op == "Reshape"]
reshape[0].inputs[1].values[0] = batch

onnx.save(gs.export_onnx(graph), "ResNet50_dynamic.onnx")
python3 convert.py

The you can replace the onnx model with the dynamic one.
We have confirmed that Deepstream can run the ResNet50_dynamic.onnx without issue in our environment.


Thank you, will try this ASAP.

I am stuck at $ make install from 1.
With python cannot find setuptools with setuptools installed.
Please help, four days i am trying :-(


Sorry for the late update.

Please try the following to see if helps:

$ sudo apt-get update
$ sudo apt-get install python3-pip
$ sudo pip3 install -U pip testresources setuptools
