Pipeline freezes when secondary batchsize less than detected objects

Hi,
I have a pipeline with primary face detector and a secondary face recognizer. The secondary recognizer operates on the faces detected by the primary detector. I am using nvinfer for primary inference and nvinferserver for secondary inference.
The issue happens when the number of faces detected by the by primary detector is more than the batch-size of secondary inference(secondary_batch_size < total face detected of all channels). In this case it freezes, gpu-util % goes to zero and cpu also goes to zero but memory is still occupied on gpu. The number of faces can be of any number and number of streams can also upto 15. Is there a way for the pipeline to not freeze if num face detected goes beyond the secondary batch size and also to loop through the remaining faces in next batch?

There is another issue, the primary detecter is very fast and secondary is slow to catch up to the detected faces(will get stuck for few seconds in some cases).
Is there a way to control the fps of stream in the pipeline for each source other than dropping frame? The source fps can be controlled for rtp source but if a file source is given, the pipeline seems to be running at highest fps possible. I have tried videorate plugin with capsfilter but that doesn’t seem to work.

Thanks.

Hi @duttaneil16,
Sorry for delay!
Did you get this issue fixed?

If not, could you capture the log with below steps:

  1. export GST_DEBUG="*:4"
  2. run you applicatipon
  3. capture all the logs

Hi @mchi,
I have captured the log for two cases. I have set the secondary batch size to 12. I have used 3 streams for the test case.
The first case I have used 3 streams with 4 faces-per-frame of each stream.
Here total faces detected == batch_size(no freezing) - temp1.log
I have stopped inference after 20 frames
temp1.log (287.3 KB)

For the second case, I have used 2 streams with 4 faces-per-frame and 1 stream with 5 face-per-frame. Here the total faces detected > batch size(freezing happens)- temp2.log
Here the pipeline stops after 1 frame and CPU% and GPU util goes to 0
temp2.log (263.9 KB)

The pipeline freezes after displaying following logs:

Src id 1 timediff: 1.000000
Frame Number = 0 Number of objects = 4
Src id 0 timediff: 1.000000
Frame Number = 0 Number of objects = 4
Src id 2 timediff: 1.000000
Frame Number = 0 Number of objects = 5

No obvious clue in the logs, could you share the config file?

Hi,
Here I have set primary batch size as 5 and secondary batch size as 25. I use 4 videos with 5 faces in them and the fifth video having 6 faces in them. It freezes for all cases where total num faces > sgie batch_size

Hi,
The post seems to be inactivate for a long time now.
Are there any updates?

I found a similar issue in another topic with the same issue.
The link to the topic - Raw tensor output

The reason there is described as follows:-

When I enable exporting of tensor metadata, the NvDsInferTensorMeta keeps reference to tensor_out_object (GstNvInferTensorOutputObject). It causes that all resources allocated by batch are released only if the whole batch is processed. But it also uses nvinfer->pool, which is of limited size, and each object from the batch gets one resource from the pool. In the situation when there is more objects in the batch than the pool size is, deadlock happens. The reason is that the next object in the batch waits for the resource from the pool but the pool is not freed until the whole batch is processed. In other words, the code in function gst_nvinfer_process_objects should check the number of objects according to the pool size. I have found this problem just because my cluster settings weren’t perfect and the primary inference sent too many objects to secondary inference but it should have worked anyway.

There the issue is with nvinfer plugin while “output-tensor-meta" is set to 1. I face the same issue while “output_tensor_meta: true” in nvinferserver plugin config. I cannot resolve the error in the plugin as it is not public.

Kindly update the plugin to handle such cases.
Is there a way to get this bug fixed by changing the code from my end?

Thank you for the information. It is a known issue when “output_tensor_meta” enabled.
there are 2 Workarounds:
a. Increase SGIE’s max-batch-size to a larger value. e.g. max_batch_size: 30 . then you can have at most 30*10=300 faces. Note: extra.output_buffer_pool_size must be <=10.
b. Even SGIE nvinferserver is not opensouced, but PGIE nvinfer-plugin is opensouced. If 250 is acceptable. you can update nvinfer code or custom-parse to limit output faces number less than 250.

Hi @Fiona.Chen

For
a. The primary model can detect up to 100 objects accurately, so to support 10 channels max_batch_size: 1000(100*10) which does not seems viable.
Also, read about extra.output_buffer_pool_size in the documentation but did not understand its purpose. Presently I have set extra.output_buffer_pool_size:10. Could you elaborate its use?

b. The model I use is a tensorflow graphdef and is not directly convertible to tensorrt plan so have to stick with nvinferserver.

Hope the issue is resolved as part of bug fixes for next release of deepstream. If there is a plan for this please let me know.

Thanks.

The output_buffer_pool_size description is https://docs.nvidia.com/metropolis/deepstream/dev-guide/text/DS_plugin_gst-nvinferserver.html#id30
This issue is under tracking now. We will inform in the forum when the fix and release is ready.
