SeeDot: ProtoNN X86 generated code (32-bit) gives segmentation fault about edgeml

[sridhargopinath]

Hi @eirikvaa,

Thank you for your interest in SeeDot.

Could you please provide the exact command line used to generate code so that I can reproduce the error at my end? Also, did the errors occur after you modified SeeDot.py and main.py, or with the unmodified code?

Thanks,
Sridhar

For the ProtoNN implementation I have used exactly the same command line arguments as in the tutorial provided.

Also, did the errors occur after you modified SeeDot.py and main.py, or with the unmodified code?

The error did indeed occur after I had modified SeeDot.py and main.py.

• Diff of main.py vs main86.py
• Diff of SeeDot.py vs SeeDot86.py

I am sure that I have introduced some error along the way, but not sure where. I hope the diff of the two pairs of files are helpful. I can also provide bigger parts of the project if necessary.

It is hard for me to go through the diff to figure out the error. I have another suggestion. After SeeDot explores multiple programs, it will generate x86 code for the testing set in a temporary directory and executes that to obtain the accuracy of the fixed-point code. You can find this code in TEMPDIR/seedot_fixed.cpp. You can modify this code accordingly.

I can understand that. Ok, I will try that and report back, thank you very much for helping me out.

Everything works! I think it just boils down to copying the wrong set of files into the output directory. Thank you very much for your help.
