Could not export onnx.

[Domwis-IR]

I tried export.py but could not do it because it didn't get the right input.

I guess the model architecture is still same with the OpenPCDet. But I don't know what to do first to export onnx from this file.
My torch version is 1.12.1+cu102, cuda version is 11.3 and onnx version is 1.12.0

@Domwis-IR I am working on the same issue. Did you solve it?

[rjwb1]

@Domwis-IR this was due to using the wrong version of PCDet. To solve this I created a docker container with torch 1.8.1 and PCDet at the HEAD reference by the submodule

[Domwis-IR]

Thank you so much with your reply. I will try too!

[jrb-cobot]

@rjwb1 could you share your Dockerfile?

[rjwb1]

@jrb-cobot find here, I had to modify it slightly as I have a customised workflow but hope this helps

@rjwb1 I built the image using the dockerfile you provided, and used the container created from the image . But the command "python exporter.py --ckpt pointpillar_7728.pth"could not do it.Could you provide some help?

Could you provide more information about the issue? Perhaps the traceback

@rjwb1 Thanks for your replytation! I uesd your dockerfile for builting container and then solved problem.Thanks!

May I ask what environment your docker is in? x86 or Xavier/Orin？

[rjwb1]

This docker file is for x86. Please check the README.md inside the docker directory for usage

You can modify the last two lines in your Dockerfile(add "-c"),like this:
ENTRYPOINT ["/bin/bash", "-c"]
CMD ["/bin/bash", "-c"]

I'm still working on this issue. I'd like to keep to the current version of OpenPCDet so that I can use the latest models and features. If anyone has made progress using version 0.6.0+, please let me know.

Do you have any progress? I can't find the difference that led to the problem between v0.5 and v0.6. I'm looking forward to your reply. Thank you very much!

[xixioba]

Is there any progress about openPCDet v0.6?
