Onnx-tensorrt: Error on python3 setup.py build

[Semihal]

I tried installing on sensor rts TensorRT 7 for python 3 but got the following error::

Hi, I met the same problem. Have you found out any solution? @Semihal

[Semihal]

@1LOVESJohnny , Hi!
Unfortunately not :(

[Semihal]

@1LOVESJohnny , I still use without Python3, just using bash: command onnx2trt.

[1LOVESJohnny]

@Semihal Thanks for your reply! I just tried to use 'onnx2trt' directly, but I met another problem:
CUDA initialization failure with error 35. Please check your CUDA installation.

Have you ever met this?

Hi all, I found a way to get it to work (not sure if it's a hack or not). Add #define TENSORRTAPI at the top of NvOnnxParser.h, and re-run python setup.py install. I believe the error comes from swig seeing a syntax error with TENSORRTAPI.

@peasant98 Thanks! I'll give it a try today. BTW, I solved my CUDA problem:

by updating my local environment from CUDA 10.0 to 10.2. Then the problem is gone.

@1LOVESJohnny, hi!

Unfortunately, I don't have the ability to upgrade the version.

sudo apt-get install swig

@Kevin-Delnoije , Hi! Swig is installed.

[CasonTsai]

@peasant98 i finished it ,thx,it's because my setuptools' version it too old

[chiehpower]

Hi all, I found a way to get it to work (not sure if it's a hack or not). Add #define TENSORRTAPI at the top of NvOnnxParser.h, and re-run python setup.py install. I believe the error comes from swig seeing a syntax error with TENSORRTAPI.

Thanks so much!
It worked for me!!!

@brianegge How to I apply this patch ?

[brianegge]

You can apply with the patch command, but for something small like this, just edit each file. Delete the lines showing a '-' in front and add the lines with a '+'.

[GabbySuwichaya]

After changing .... I have received the following error.

Just to confirm, before changing the error that I have seems to be the same as the topic of this issue, as shown below:

Here, I have also attached the scripts that I have made changed according to your comments.

Here, I attached them as .txt because I could not attached them with the original .py and .h

setup.txt

NvOnnxParser.txt

[brianegge]

Sorry, my patch is for compiling on Jetson Nano. This patch won't help with x86.

[kevinch-nv]

I've recently modernized the setup.py installation script in https://github.com/onnx/onnx-tensorrt/pull/559. Can you try running the updated setup.py?

[kevinch-nv]

Closing due to inactivity - please upgrade to the latest TRT version and try installing the python library again. If that doesn't work, feel free to open a new issue.
