DeepStream SDK 4.0.1 with Nvidia Tesla K40 - deepstream-app throwing Bus error

Accelerated Computing Intelligent Video Analytics DeepStream SDK
1

I have deepstream sdk 4.0.1 installed on ubuntu 18.04 and trying to run deepstream-app. My system has a Tesla K40 GPU and I don’t know if it’s supported by deepstream sdk.

Deepstream requirements are met, deepstream-app --version-all returns:

deepstream-app version 4.0.1
DeepStreamSDK 4.0.1
CUDA Driver Version: 10.1
CUDA Runtime Version: 10.1
TensorRT Version: 5.1
cuDNN Version: 7.6
libNVWarp360 Version: 2.0.0d5

nvidia-smi returns:

Before running deepstream-app, I modified config_infer_primary.txt config_infer_secondary_carcolor.txt config_infer_secondary_carmake.txt config_infer_secondary_vehicletypes.txt files and set network-mode=0 (i.e. FP32).

I ran deepstream-app with /opt/nvidia/deepstream/deepstream-4.0/samples/configs/deepstream-app/source4_1080p_dec_infer-resnet_tracker_sgie_tiled_display_int8.txt

I changed source4_1080p_dec_infer-resnet_tracker_sgie_tiled_display_int8.txt and enabled sink1 instead of sink0. The following is the output:

amer@amer-server1:~$ deepstream-app -c /opt/nvidia/deepstream/deepstream-4.0/samples/configs/deepstream-app/source4_1080p_dec_infer-resnet_tracker_sgie_tiled_display_int8.txt

Not sure what’s going on, any ideas anyone?

2

Can you “export DISPLAY=:0” and try again ?

3

echo $DISPLAY already gives :0

I tried “export DISPLAY=:0” anyway and ran the app, same bus error.

4

Can you try the default config? What’s result?

I tried with default config, got bus error. I tried debugging with gdb, here’s the output and gdb backtrace:

If TRT sample like trtexec works on K40 then DS should work - we have not tested on Kepler series like K40. you should move to a Tesla based architecture onwards GPU - latest GPU like P4 or P40 or T4.
