Load your newly created Tensorflow frozen model and convert it to UFF uff_model. > import tensorrt as trt > # This import should succeed. LogSeverity. The basic idea is feed subgraphs containing TRT compatible operators to TRT engine for compilation and execution, and compile and run the rest of operators in the graph using TVM. asarray(pics). ops import data_flow_ops from tensorflow. ModuleNotFoundError: No module named 'tensorrt'. import numpy as np 3. The current release of TensorRT version is 5. Ok, so an update. NVIDIA TensorRT™ is an SDK for high-performance deep learning inference. save(output_saved_model_dir) To test this, I took a simple example …. py images/image1. autoinit import tensorrt as trt import sys, os. Attempting to. 1 TensorRT Version = 7. Linear model quantization converts weights and activations from cat < convert_to_rt. ArgumentParser(description. 16显卡:TeslaP4cuda9. Load your newly created Tensorflow frozen model and convert it to UFF uff_model. I am not sure whether it is a tensorrt bug or I am doing something wrong. from tensorflow. sh Download pretrained model. autoinit import tensorrt as trt import sys, os. from tensorflow. You can use scp/sftp to remotely copy the file. NVIDIA TensorRT is a high-performance deep learning inference optimizer and runtime that delivers low latency and How to accelerate your neural net inference with TensorRT" - Dmitry Korobchenko, Data Summer Conf 2018.
