@AastaNV ,

while running the "python3 main.py object_7.jpg "
I am facing the below error,

please advise

I found the solution. The libflattenconcat must be recompiled.

cd /usr/src/tensorrt/samples/python/uff_ssd/
mkdir build
cd build
cmake -D CMAKE_INSTALL_PREFIX=/usr/local ..
cp libflattenconcat.so /home/myuser/mycode

[sdario1980]

Thank you. However (it might be a stupid question, but in a linux beginner) where is the libflattenconcat.so generated? i can't find it.

Thanks

[Adnaram]

It should be in /usr/src/tensorrt/samples/python/uff_ssd/build if you run the commands above

I found the solution. The libflattenconcat must be recompiled.

cd /usr/src/tensorrt/samples/python/uff_ssd/
mkdir build
cd build
cmake -D CMAKE_INSTALL_PREFIX=/usr/local ..
cp libflattenconcat.so /home/myuser/mycode

remember to do

make
after cmake as per https://forums.developer.nvidia.com/t/problems-with-ssd-mobilenet-v2-uff/74326/17

Need help. I have tried this on Jetson AGX

cd /usr/src/tensorrt/samples/python/uff_ssd/
mkdir build
cd build
cmake -D CMAKE_INSTALL_PREFIX=/usr/local ..
