ImportError:没有名为“tensorrt”的模块

Question

我使用Debian安装程序在我的虚拟机上安装了TensorRT。如果我运行"dpkg -l | grep TensorRT“，我会得到预期的结果：

ii  graphsurgeon-tf                                             5.0.2-1+cuda10.0                           amd64        GraphSurgeon for TensorRT package

ii  libnvinfer-samples                                          5.0.2-1+cuda10.0                           all          TensorRT samples and documentation

ii  python3-libnvinfer-dev                                      5.0.2-1+cuda10.0                           amd64        Python 3 development package for TensorRT
ii  tensorrt                                                    5.0.2.6-1+cuda10.0                         amd64        Meta package of TensorRT
ii  uff-converter-tf                                            5.0.2-1+cuda10.0                           amd64        UFF converter for TensorRT package

然而，当我尝试在python中导入它时，我得到了：

File "<stdin>", line 1, in <module>
ImportError: No module named 'tensorrt'

我做错了什么？

Answer 1

我也有同样的错误，通过安装以下两个包解决了这个问题：

# from TensorRT Tar Package ( TensorRT-5.0.2.6/python/ ) 
pip3 install tensorrt-5.0.2.6-py2.py3-none-any.whl  
# pycuda
pip3 install pycuda 

# libnvinfer 5.0.2-1
# libnvinfer-dev 5.0.2-1
# libnvinfer-samples 5.0.2-1
# python3-libnvinfer 5.0.2-1
# python3-libnvinfer-dev 5.0.2-1
# tensorrt 5.0.2.6

Answer 2

只需运行以下命令：

pip install nvidia-pyindex
pip install nvidia-tensorrt

Answer 3

两个建议：

如果您同时安装了python 2和python3，请检查pip list (LD_LIBRARY_PATH)

• if /or pip3 list

中是否安装了软件包，请确保已添加pip和/或python3。do your your path
