I am building engine file for maskrcnn application.
My application runs using deepstream-app.
When building engine, I have error as follows.

cnn.etlt_b1_gpu0_fp16.engine open error

I have already updated plugin 7.2.2

Can you upgrade to DS-6.3 ? DS-5.0 version is too old

No can’t. I can’t take out the device.
It was working before.
I downlaoded from the link and https://nvidia.box.com/shared/static/ezrjriq08q8fy8tvqcswgi0u6yn0bomg.1 -O libnvinfer_plugin.so.7.0.0.1 still have same issue.
I need to build myself.

May I know what is the error. When I build as

/usr/local/bin/cmake .. -DGPU_ARCHS="53 62 72" -DTRT_LIB_DIR=/usr/lib/aarch64-linux-gnu/ -DCMAKE_C_COMPILER=/usr/bin/gcc -DTRT_BIN_DIR=`pwd`/out

Building for TensorRT version: 7.1.3, library version: 7
-- The CUDA compiler identification is unknown
CMake Error at CMakeLists.txt:46 (project):
  No CMAKE_CUDA_COMPILER could be found.

  Tell CMake where to find the compiler by setting either the environment
  variable "CUDACXX" or the CMake cache entry CMAKE_CUDA_COMPILER to the full
  path to the compiler, or to the compiler name if it is in the PATH.


-- Configuring incomplete, errors occurred!

It is working now. Build engine at local device and engine file is copied to remote device.
