power measurement tool on demos

Hi,

I am using the board i.MX 8M PLUS PEVK and have been going through the machine learning user guide. I am having 2 issues with running the power measurement tool on the provided gstnninference-demos provided
by the guide.
1) Running the profiler (through SSH per the guide recommendation) with gstnninferencedemo-mobilenet-ssd-camera work as expected for about 100-150 seconds after which the power measurement tool does no longer work and produces the following error.

Exception in thread Thread-1:
Traceback (most recent call last):
File "/usr/lib/python3.8/threading.py", line 932, in _bootstrap_inner

File "<__array_function__ internals>", line 5, in concatenate
ValueError: all the input arrays must have same number of dimensions, but the array at index 0 has 2 dimension(s) and the array at index 1 has 1 dimension(s)

 


2) Running the profiler with gstnninferencedemo-mobilenet-ssd-video with a .m4v fileformat does not work at all. I have tested different types of fileformat and encodings, none of the different combination of the two fixes the problem. The application crashes after 1-3 frames into the video. I tried attaching the flags for debug logging into a file by adding: GST_DEBUG_FILE=demoVideo.log GST_DEBUG=9 gst-launch-1.0 ...
However upon running this new pipeline the application instantly crashes with the pipeline error "GST_DEBUG_FILE=demoVideo.log: command not found". Why does this not work for the inference video demo pipeline but work for other pipelines? For example running the pipeline:
GST_DEBUG_FILE=test123.log GST_DEBUG=9 gst-launch-1.0 videotestsrc ! waylandsink
works without any problem. As per the userguide the power measurement tool should work fine with the inference demo application provided by the guide itself. In order to attempt some type of debugging I modified one of the pipelines provided by the userguide:

GST_DEBUG_NO_COLOR=1 GST_DEBUG_FILE=testscriptVidv2.log GST_DEBUG=9 gst-launch-1.0 --no-position filesrc location=vtest.yuv ! videoparse width=1280 height=720 framerate=25/1 ! \
tee name=t t. ! queue max-size-buffers=2 ! imxvideoconvert_g2d ! video/x-raw,width=300,height=300,format=RGBA ! \
videoconvert ! video/x-raw,format=RGB ! tensor_converter ! \
tensor_filter framework=tensorflow-lite model=ssd_mobilenet_v2_coco_quant_postprocess.tflite custom=Delegate:NNAPI ! \
tensor_decoder mode=bounding_boxes option1=tf-ssd option2=coco_labels.txt \
option3=0:1:2:3,50 option4=1280:720 option5=300:300 ! mix. t. ! queue max-size-buffers=2 ! \
imxcompositor_g2d name=mix sink_0::zorder=2 sink_1::zorder=1 ! waylandsink sync=false

Which by grepping the log file for errors gave the following output:

Any help, hints or pointers would be greatly appreciated.

Hi,

Can you give more details about PMT please ? Which OS are you using, which rails are you probing ?

Thanks
