No module named 'graphsurgeon

Note: Before issuing the following commands, you'll need to replace 5.1.x.x with your specific TensorRT version. The following commands are examples.

1. Install the following dependencies, if not already present:
   • Install the CUDA Toolkit 9.0, 10.0 or 10.1
   • cuDNN 7.5.0
   • Python 2 or Python 3 (Optional)
2. Download the TensorRT tar file that matches the Linux distribution you are using.
3. Choose where you want to install TensorRT. This tar file will install everything into a subdirectory called TensorRT-5.1.x.x.
4. Unpack the tar file.

   $ tar xzvf TensorRT-5.1.x.x.Ubuntu-1x.04.x.x86_64-gnu.cuda-x.x.cudnn7.x.tar.gz

   Where:
   • 5.1.x.x is your TensorRT version
   • Ubuntu-1x.04.x is 14.04.5, 16.04.4 or 18.04.1
   • cuda-x.x is CUDA version 9.0, 10.0, or 10.1
   • cudnn7.x is cuDNN version 7.5
   This directory will have sub-directories like lib, include, data, etc…

   $ ls TensorRT-5.1.x.x
   bin  data  doc  graphsurgeon  include  lib  python  samples  targets  TensorRT-Release-Notes.pdf  uff
   

5. Add the absolute path to the TensorRT lib directory to the environment variable LD_LIBRARY_PATH:

   $ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:

6. Install the Python TensorRT wheel file.

   $ cd TensorRT-5.1.x.x/python

    

   If using Python 2.7:

   $ sudo pip2 install tensorrt-5.1.x.x-cp27-none-linux_x86_64.whl

    

   If using Python 3.x:

   $ sudo pip3 install tensorrt-5.1.x.x-cp3x-none-linux_x86_64.whl

7. Install the Python UFF wheel file. This is only required if you plan to use TensorRT with TensorFlow.

   $ cd TensorRT-5.1.x.x/uff

    

   If using Python 2.7:

   $ sudo pip2 install uff-0.6.3-py2.py3-none-any.whl

    

   If using Python 3.x:

   $ sudo pip3 install uff-0.6.3-py2.py3-none-any.whl

    

   In either case:

   $ which convert-to-uff
   /usr/local/bin/convert-to-uff
   

8. Install the Python graphsurgeon wheel file.

   $ cd TensorRT-5.1.x.x/graphsurgeon

    

   If using Python 2.7:

   $ sudo pip2 install graphsurgeon-0.4.1-py2.py3-none-any.whl
   

    

   If using Python 3.x:

   $ sudo pip3 install graphsurgeon-0.4.1-py2.py3-none-any.whl
   

9. Verify the installation:
   1. Ensure that the installed files are located in the correct directories. For example, run the tree -d command to check whether all supported installed files are in place in the lib, include, data, etc… directories.
   2. Build and run one of the shipped samples, for example, sampleMNIST in the installed directory. You should be able to compile and execute the sample without additional settings. For more information about sampleMNSIT, see the TensorRT Sample Support Guide.
   3. The Python samples are in the samples/python direc
10. python包一定安装，在使用python API转换tensorflow model的时候，会报错找不到graphsurgeon库．
