I don’t find any file name libnvds_nvmultiobjecttracker.so in /opt/nvidia/deepstream/deepstream/lib/
Where can i find this file?

3

Which deepstream version your are using?

4

Hi amycao , I’m using Deepstream 5.1

5

6.0 tracker have this. you should use old tracker library.

6

Do you mean I should download the DeepStream 6.0 , and copy this file to 5.1 lib?

7

HI, I copy this file in my system,but when I run the test,this error is still exist

8

Tracker in version 5.1 and 6.0 is different, you can not copy 6.0 tracker library to 5.1 package. you only can use tracker library from version 5.1 if you use version 5.1

9

OK，but there is no tracker.so file in my deepstream5.1 ,so I want to know where can I find it …

10

Refer to configuration source4***, there tracker groups in this file. you can find how to use it.
