[BUG] pose_engine.py runtime exception about fall-detection HOT 5 OPEN

@ivelin

Can you please provide me with a sample test fall image so I can reproduce the error and fix it?

from fall-detection.

No, because the error is intermittent and since it is not handled in a way that provides much context, I cannot correlate the message to an image. Please think how we can better encapsulate this error with a contextual information in the log that allows us to track it down.

ok...will check it.

I have tried to trace this issue but unable to locate the bug.
This function use output data(heatmap_data, offset_data) that are generated from TFLite posenet model.

pose_kps[i, 0] = int(remap_pos[0] + offset_data[max_val_pos[0], max_val_pos[1], i])

pose_kps[i, 0] = int(remap_pos[0] + offset_data[max_val_pos[0], max_val_pos[1], i])
TypeError: only size-1 arrays can be converted to Python scalars

And this error is raised when the function expects a single value but you pass an array instead.

I am trying to check at what circumstance model output is different. But not able to find it.
Can you please help me with your thoughts to deal with this bug?

thanks

It's not obvious to me what the issue is. Is it possible that
remap_pos[0] returns anything but a scalar?
Same question for offset_data[max_val_pos[0], max_val_pos[1], i].

One of these two returns a list or array, which confuses int().

I suggest surrounding these lines with an exception handling block that provides as much context as needed. That way the next time this happens, we would know exactly what caused it.
