[Perception Modules] how i can run perception module and modify algorithm in module?

[duongnxptit]

I want to test my perception algorithm, so i tried to run Perception module follow guide but it's not work like guide. What should i do to test perception algorithm without hardware in apollo?

System information

• OS Platform and Distribution (e.g., Linux Ubuntu 18.04): Ubuntu 18.04
• Apollo installed from (source or binary): Source
• Apollo version (3.5, 5.0, 5.5, 6.0): 5.0
• Output of apollo.sh config if on master branch: r5.0.0 branch

Steps to reproduce the issue:

I follow guide to run perception module How to Run Perception Module on Your Local Computer.

seems there is no cuda library. could you please make sure cuda is installed correctly.

Thanks for your help, @daohu527 ! i have already install cuda but still error like that. My cuda and nvidia version:

Should i resintall cuda version 11? And can i change perception algorithm then test with play demo_3.5.record?

If your error is the same as the one you posted before. could you pls check the path of the dynamic link library use below cmd.

ldd /apollo/bazel-bin/modules/perception/onboard/component/libperception_component_camera.so | grep cuda

If you find the path, and then check if the libcuda.so.1 is in the path.

Run cmd then result:
libcuda.so.1 => /usr/lib/x86_64-linux-gnu/libcuda.so.1 (0x00007fcdd6c4f000)
After that, i checked libcuda.so.1 in this path, it is already in here.

[daohu527]

use cmd to check if is a symbolic link.

file /usr/lib/x86_64-linux-gnu/libcuda.so.1

[duongnxptit]

Yes, its a symbolic link.
/usr/lib/x86_64-linux-gnu/libcuda.so.1: symbolic link to libcuda.so.450.80.02

[daohu527]

then

1. find the libcuda.so.450.80.02 file, if not then it's the problem
2. if find the file, then use file libcuda.so.450.80.02 again
