Hey @snow_xue,

Welcome to the Hailo Community!

I’ve been looking at the error you’re hitting with hailomz compile on the yolov5m model, and it looks like there’s a syntax issue in your model script file. The ParseException is complaining about the keyword change at line 2, column 1 of your yolov5m.alls file, which suggests the parser isn’t expecting that keyword there.

Here’s what I’d suggest trying:

First, can you share the .alls file you’re using? That’ll help us spot exactly what’s going wrong. If you’re using the current version from the model zoo, check if it’s been updated recently. You might want to look at the default one here and compare it to what you’ve got:

/home/user/work/hailo_ai_sw_suite/sources/model_zoo/hailo_model_zoo/cfg/alls/hailo8/base/yolov5m.alls

My guess is there’s either a typo in your script, or there’s a mismatch between your version and what’s expected. Once we see the file, we should be able to get this sorted pretty quickly.

Let me know what you find!

Thanks, actually we use the default one.

Hey @snow_xue,

The YAML syntax looks good to me overall! But I noticed something that might be off with the last character on that first line - could be a corruption issue there.

If you’re still getting parsing errors after fixing that, it might be worth checking for any hidden or non-printable characters at the end of the line. Sometimes those sneak in and cause problems even when everything looks fine visually.

I think there has no corruption issue .

I have not change the file after I install the package. Below link is the file
