Inception_v3.nb is not a core dump: File format not recognized

VIM3

Will inception_v3.nb converted from Tensorflow 2.1 be usable by aml-npu 6.4.0.4 on VIM3 ?

  • I did specify Fenix while building EXECUTABLE inceptionv3

  • Segmentation fault on VIM3

When I tried to debug on VIM3, I got the following ERROR message:

./inception_v3.nb" is not a core dump: File format not recognized
  • Then, I tried aml_npu_sdk/linux_sdk/linux_sdk_6.3.3.4 on VIM3 without re-compile at all, but failed with Segmentation fault as well.

Clearly, this has something to do with either inceptionv3 or inception_v3.nb.

I just wonder if the source of aml_npu_sdk can be provided for us to build by ourselves?

Is 6.3.3.4?

Just a data file, not an executable

Hi, Frank, I just had aml-npu upgraded this morning, from 6.3.3.4 to 6.4.0.4 .
However, my aml-apu-sdk is still of version 6.3.3.4

Is it possible that this is caused by the driver and sdk are of different versions?

@jiapei100 No impact

Hi, Frank… Finally, I figured out how to build the demo inceptionv3 onboard directly, with aml-npu 6.4.0.3, but still failed to run it with Segment Fault…

  • I failed to run the demo coming with the SDK
  • I successfully built the demo with aml-npu from repo, but failed to run it…

Any further suggestions?

The model (the *.nb file) I converted can be found https://app.box.com/s/d7szbd3zvvv8mybj5afsdspgx1dga0lh

Any further suggestions?

Cheers

Great… Finally, it’s running… What a long journey…

Thank you very much Frank…

Now, start coding with npu… Thank you
