ImportError: No module named 'tensorrt'

I installed TensorRT on my VM using the Debian Installation. If I run "dpkg -l | grep TensorRT" I get the expected result:

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

Yet when I try to import it in python I get:

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

What am I doing wrong?

If you are in a virtual environment, go to the following path to check if it exists.

(deepNN) agxxavier@agxxavier-desktop:~/miniforge3/envs/deepNN/lib/python3.6/site-packages$ ls

Use the following command to check where tensorrt.so is located

(base) agxxavier@agxxavier-desktop:~$ sudo find / -iname "*tensorrt*"

and to create a soft connection in your virtual environment.

(deepNN) agxxavier@agxxavier-desktop:~/miniforge3/envs/deepNN/lib/python3.6/site-packages$ ln -s /usr/lib/python3.6/dist-packages/tensorrt/tensorrt.so tensorrt.so

just run these commands:

pip install nvidia-pyindex
pip install nvidia-tensorrt

You need to import in python3 environment as you seems to have installed TensorRT for python3. So it does not get import on python2.

i had same error, solved it by installing following 2 packages:

# 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

two suggestions:

  1. make sure that your TensorRT is added do your path (LD_LIBRARY_PATH)
  2. if you have both python 2 and python3 installed, check for package installation in pip list and/or pip3 list
