Got problem when i tried to use tensorrt

Aftering cloning jetson-inference and downloading submodules from "GitHub - dusty-nv/pytorch-segmentation: Training of semantic segmentation networks with PyTorch "
and cd jetson-inference
mkdir build
cd build
cmake …/
Then it went wrong with

Note: this project uses git submodules in the source tree.
if you haven’t already, run the following command from
the project’s root directory:

       git submodule update --init

what should i do next?

#2

Hi @329512443, did you clone with git --recursive?

If not, run this:

cd /path/to/your/jetson-inference
git submodule update --init
cd build
cmake ../
#3

i think that the
“git submodule update --init"
is downloading from
“” GitHub - dusty-nv/pytorch-segmentation: Training of semantic segmentation networks with PyTorch “”
so i just use
“git clone GitHub - dusty-nv/pytorch-segmentation: Training of semantic segmentation networks with PyTorch”
instead
wont it work?
but maybe its something to do with the network,after i ran " git submodule update --init " it just didnt work

#5

Hi,

Just give it try.
The cmake works correctly with the following command:

$ git clone https://github.com/dusty-nv/jetson-inference
$ git submodule update --init
$ mkdir build
$ cd build/
$ cmake ../
...

Please help to give it a try.
Thanks.
