Thanks for using our code.
Have you already tried the example demo of rangenet_lib?
You may test the rangnet_lib first. It could be the problem of tensorrt of cuda version.
You could find more details here: https://github.com/PRBonn/rangenet_lib
from semantic_suma.
Thanks for the reply. Yes, the Rangnet_lib have the same error also.
Here is my environment:Ubuntu18.04, TensorRT 6.01+cuda10.1.

It would be much better if you could provide more details about the compiling and error message/log.
from semantic_suma.
This is the output of when I run the Rangnet_lib:
scan: /root/catkin_ws5/src/rangenet_lib/example/000000.bin
path: /root/catkin_ws5/src/rangenet_lib/example/model/
verbose: 1
Setting verbosity to: false
Trying to open model
Trying to deserialize previously stored: /root/catkin_ws5/src/rangenet_lib/example/model//model.trt
Could not deserialize TensorRT engine.
Generating from sratch... This may take a while...
Trying to generate trt engine from : /root/catkin_ws5/src/rangenet_lib/example/model//model.onnx

I have debug to the error line: netTensorRT.cpp, line 509 builder->platformHasFastFp16();
the value of "builder" is 0;
The error from TensorRT is almost sure,but how can I solved this .
Thanks.
from semantic_suma.
Yes, it seems to be a problem caused by the TensorRT.
I didn't meet such a problem so far. I just googled it. It could be a problem with the mismatching of your graphic card and the TensorRT version.
Could you please also report your graphic card and the corresponding driver setups?
You may also give it a try with another version TensorRT, e.g. TensorRT-5.0.

Thanks. I have try with TensorRT5.1 version, the last error had disappear,while another error occur.......

Sorry for the late reply. It seems it cannot find the configuration file or something wrong when it parses the file.
You could try to run the visualizer with a specific path of the configuration file, like:
./visualizer /path/to/config/file

Hi @xuguangyun
Is there any update about this issue?
from semantic_suma.
Thanks a lot! I have try to run the visualizer with a specific path of the configuration file, the problem solved!

Hi @Chen-Xieyuanli I am facing the same issue. I have successfully built the RangenetLib. Could you help out? In this case it doesnot seem to a issue of file location.
It displays this output while running the visualizer script.

Hey @Dhruv2012, sorry for the late reply. I never encountered such a problem, but there are some solutions provide by other users #7. It seems to be a problem caused by GTSAM.
