We are trying to implement a TensorRT engine using Python and then use the whole module as a service from C++. autoinit in the main thread, as follows. 2. 03 CUDA Version: 11. driver as cuda import pycuda. Just before this Following this TensorRT developer guide step by step, we could run ONNX with TensorRT. Environment TensorRT Version: 7. engine file) from disk and performs single inference. File metadata @zdai257 I may not have the same setup as you, but I am successfully running tensorRT inference (and other pycuda calls to the GPU) from a ROS callback, sort of. a-doering a-doering. 0 and generated TensorRT engine. Closed Akshaysharma29 opened this issue Apr 6, 2020 · 10 comments pycuda. push() My assumption here is that the context is preserved between the list of gpuinstances is created and when the threads use them, so each device is sitting pretty in its own context. 04 Cuda 11. •For a summary of new additions and updates shipped with TensorRT-OSS releases, please ref •For business inquiries, please contact researchinquiries@nvidia. Now I’m trying to load different contexts in same python script. PyCUDA; Mxnet with TensorRT support; Installation. driver as cuda import numpy as np import pycuda. your callback function, instead of using import pycuda. driver. driver as cuda. import os import time import cv2 import matplotlib. Device(devid) #this is passed at instantiation of class self. I’ve checked pycuda can install on local as below: But pyCUDA is required to allocate GPU memory with python interface. import numpy as np import pycuda. e. conda create --name env_3 python=3. _driver. After that I was able to use GPU for pytorch model training. I'm trying to run the standard pyCuda example: # --- PyCuda Continuing the discussion from Import pycuda. For installation instructions, refer to the CUDA Python Installation documentation. Toggle table of contents sidebar. Second do the model inference on the same GPU, but get the wrong result. pip3 install pycuda; Process overview. Getting Started with TensorRT; Core Concepts; Writing custom operators with TensorRT Python plugins; You signed in with another tab or window. 4 CUDNN Version: 8. Here are a few key code examples used in the earlier sample application. 11: 2363: December 30, 2021 """ An example that uses TensorRT's Python api to make inferences. This problem can occur with the engine file provided by the author, and can be solved using your own engine file. Install version "1. driver as cuda import tensorrt as trt from PIL import Image import pdb class HostDeviceMem(object): def __init__(self, host_mem, device_mem): self. make_context() self. ERROR) self Issue after installing TensorRT - PyCUDA ERROR: The context stack was not empty upon module cleanup. 22631 Build 22631 Python Version (if You signed in with another tab or window. But I stacked in understanding of doing the inference with trt. app_context():, i create context, runtime and engine for TensorRT. 18 ENV NVIDIA_VISIB Description Getting different results while inference the same torch tensor data Using TRT Python interface and torch forward. pop() " dose not work，return “”PyCUDA ERROR: The context stack was not empty upon module cleanup. Hi, I am deploying LPR model downloaded from NGC in python. make_context() logger = trt. Abstractions like pycuda. batch_size : The batch size for execution time. (I have done to generate the TensorRT engine, so I will load an engine and do TensorRT inference by multi-threading.
