YOLO3 workload

[manox]

Hi @abejgonzalez,
In an chipyard NVDLA integration PR conversation (ucb-bar/chipyard#505 (comment)) you said you have been able to run a YOLO3 workload.
Is this still possible and if so, can you briefly explain how? Thank you!

[abejgonzalez]

IIRC I just followed along with the original documentation here: https://github.com/CSL-KU/firesim-nvdla#running-yolov3-on-nvdla. You will probably have to modify the FireMarshal workload files / FireSim config files a bit (FireMarshal: to match the FireMarshal version in CY, inherit from the nvdla workload nvdla-base in this repo)(FireSim: to match the FireSim version in CY, point to a proper FireSim HW config).

Thank you @abejgonzalez,
I ran into the problem, that it needs GLIBC 2.26 but there is a higher version in the generated linux. Do I need to use an older linux version now?

Frankly I don't remember since this was so long ago. I would try to update the YOLO3 workload instead of going to a lower version of Linux... Sorry I can't be of more help.

Thank you @abejgonzalez, I am grateful for any help. Managed to build the YOLO3 workload with the newer libraries. Now the execution hangs at the following point. Maybe you can give me a hint where it could fail here.

Hi @manox .Have you fix this problem about GLIBC_2.26?

Hi @manox .Have you fix this problem about GLIBC_2.26?

That was quite a long time ago and I don't think I followed it up. Sorry.

[Yuxin-Yu]

Hello @manox , I have resolved this issue. I previously used the official nvdla_runtime, so displays GLIBC error, but when I use the nvdla-workload/nvdla-base/build-umd.sh script to generate my own nvdla_ runtime, it runs normally.
