debug for bin runtime error

1. check the library for the bin

    check the absence of the library link by the bin  // ldd libcaffe.so,  ldd /usr/src/tensorrt/bin/trtexec

    check the absence of the symbol used in the bin  // ldd -r libcaffe.so, objdump -TC  | grep 

2. use strace tool to debug the execution process

    I: Make sure the bin can run normal if everything be ok. Then Find the environment where the bin can run ok

   II: strace the normal env and the failed env, 

                 // strace /usr/src/tensorrt/bin/trtexec --deploy=/usr/src/tensorrt/data/mnist/mnist.prototxt --output=prob --fp16 --allowGPUFallback > log.in.2 2>&1 

                 // strace usr/src/tensorrt/bin/trtexec --deploy=usr/src/tensorrt/data/mnist/mnist.prototxt --output=prob --fp16 --allowGPUFallback > log.out 2>&1

                  // LD_DEBUG=all /usr/src/tensorrt/bin/trtexec --deploy=/usr/src/tensorrt/data/mnist/mnist.prototxt --output=prob --useDLACore=0 --fp16 --allowGPUFallback 2> ~/ld_debug.out 

       check if exist the descriptor open faild or acess failed and so on

       check if exist the case that use the different so

       The last weapon: Paste the error on Google or Bing.
