Instructions for x86_64 platforms

All demos in this repository, with minor tweaks, should also work on x86_64 platforms with NVIDIA GPU(s). Here is a list of required modifications if you'd like to run the demos on an x86_64 PC/server.

Make sure you have TensorRT installed properly on your x86_64 system. You could follow NVIDIA's official Installation Guide :: NVIDIA Deep Learning TensorRT documentation.

Demo #1 (GoogLeNet) and #2 (MTCNN)

  1. Set TENSORRT_INCS and TENSORRT_LIBS in "common/Makefile.config" correctly for your x86_64 system. More specifically, you should find the following lines in "common/Mafefile.config" and modify them if needed.

    # These are the directories where I installed TensorRT on my x86_64 PC.
TENSORRT_INCS=-I"/usr/local/TensorRT-7.1.3.4/include"
TENSORRT_LIBS=-L"/usr/local/TensorRT-7.1.3.4/lib"

  2. Set library_dirs and include_dirs in "setup.py". More specifically, you should check and make sure the 2 TensorRT path lines are correct.

    library_dirs = [
    '/usr/local/cuda/lib64',
    '/usr/local/TensorRT-7.1.3.4/lib',  # for my x86_64 PC
    '/usr/local/lib',
]
......
include_dirs = [
    # in case the following numpy include path does not work, you
    # could replace it manually with, say,
    # '-I/usr/local/lib/python3.6/dist-packages/numpy/core/include',
    '-I' + numpy.__path__[0] + '/core/include',
    '-I/usr/local/cuda/include',
    '-I/usr/local/TensorRT-7.1.3.4/include',  # for my x86_64 PC
    '-I/usr/local/include',
]

  3. Follow the steps in the original README.md, and the demos should work on x86_64 as well.

Demo #3 (SSD)

  1. Make sure to follow NVIDIA's official Installation Guide :: NVIDIA Deep Learning TensorRT documentation and pip3 install "tensorrt", "uff", and "graphsurgeon" packages.

  2. Patch /usr/local/lib/python3.?/dist-packages/graphsurgeon/node_manipulation.py by adding the following line (around line #42):

     def shape(node):
     ......
     node.name = name or node.name
     node.op = op or node.op or node.name
+    node.attr["dtype"].type = 1
     for key, val in kwargs.items():
     ......

  3. (I think this step is only required for TensorRT 6 or earlier versions.) Re-build libflattenconcat.so from TensorRT's 'python/uff_ssd' sample source code. For example,

    $ mkdir -p ${HOME}/src/TensorRT-5.1.5.0
$ cp -r /usr/local/TensorRT-5.1.5.0/samples ${HOME}/src/TensorRT-5.1.5.0
$ cd ${HOME}/src/TensorRT-5.1.5.0/samples/python/uff_ssd
$ mkdir build
$ cd build
$ cmake -D NVINFER_LIB=/usr/local/TensorRT-5.1.5.0/lib/libnvinfer.so \
        -D TRT_INCLUDE=/usr/local/TensorRT-5.1.5.0/include ..
$ make
$ cp libflattenconcat.so ${HOME}/project/tensorrt_demos/ssd/

  4. Install "pycuda".

    $ sudo apt-get install -y build-essential python-dev
$ sudo apt-get install -y libboost-python-dev libboost-thread-dev
$ sudo pip3 install setuptools
$ export boost_pylib=$(basename /usr/lib/x86_64-linux-gnu/libboost_python3-py3?.so)
$ export boost_pylibname=${boost_pylib%.so}
$ export boost_pyname=${boost_pylibname/lib/}
$ cd ${HOME}/src
$ wget https://files.pythonhosted.org/packages/5e/3f/5658c38579b41866ba21ee1b5020b8225cec86fe717e4b1c5c972de0a33c/pycuda-2019.1.2.tar.gz
$ tar xzvf pycuda-2019.1.2.tar.gz
$ cd pycuda-2019.1.2
$ ./configure.py --python-exe=/usr/bin/python3 \
                 --cuda-root=/usr/local/cuda \
                 --cudadrv-lib-dir=/usr/lib/x86_64-linux-gnu \
                 --boost-inc-dir=/usr/include \
                 --boost-lib-dir=/usr/lib/x86_64-linux-gnu \
                 --boost-python-libname=${boost_pyname} \
                 --boost-thread-libname=boost_thread \
                 --no-use-shipped-boost
$ make -j4
$ python3 setup.py build
$ sudo python3 setup.py install
$ python3 -c "import pycuda; print('pycuda version:', pycuda.VERSION)"

  5. Follow the steps in the original README.md but skip install.sh. You should be able to build the SSD TensorRT engines and run them on on x86_64 as well.

Demo #4 (YOLOv3) & Demo #5 (YOLOv4)

Checkout "plugins/Makefile". You'll need to make sure in "plugins/Makefile":

  • CUDA compute is set correctly for your GPU (reference: CUDA GPUs | NVIDIA Developer);
  • TENSORRT_INCS and TENSORRT_LIBS point to the right paths.
......
else ifeq ($(cpu_arch), x86_64)  # x86_64 PC
  $(warning "compute=75" is for GeForce RTX-2080 Ti.  Please make sure CUDA compute is set correctly for your system in the Makefile.)
  compute=75
......
NVCCFLAGS=-m64 -gencode arch=compute_$(compute),code=sm_$(compute) \
               -gencode arch=compute_$(compute),code=compute_$(compute)
......
# These are the directories where I installed TensorRT on my x86_64 PC.
TENSORRT_INCS=-I"/usr/local/TensorRT-7.1.3.4/include"
TENSORRT_LIBS=-L"/usr/local/TensorRT-7.1.3.4/lib"
......

Otherwise, you should be able to follow the steps in the original README.md to get these 2 demos working.
