Thank you. I finally got it working. I’d three python installations: python 2.7 coming with ubuntu, python 3.5 coming with ubuntu and anaconda python 3.5 that I’d installed myself. Got rid of Anaconda 3.5 as I couldn’t control where tensorrt is installed and made 3.5 the default one and reinstalled tensorrt, python packages as well as pycuda. Now, it’s working.
