Do inference of tao generated engine in python without deepstream

[Morganh]

It is possible. You can directly deploy the etlt model with triton-app. GitHub - NVIDIA-AI-IOT/tao-toolkit-triton-apps: Sample app code for deploying TAO Toolkit trained models to Triton

You can also refer to the preprocessing and postprocessing in
https://github.com/NVIDIA-AI-IOT/tao-toolkit-triton-apps/blob/main/tao_triton/python/entrypoints/tao_client.py and
https://github.com/NVIDIA-AI-IOT/tao-toolkit-triton-apps/blob/main/tao_triton/python/postprocessing/yolov3_postprocessor.py

More, you can also search and refer to some topics in forum.
For example,

Inferring Yolo_v3.trt model in python

@Morganh Actually my model input size is 1472X960. So if resize the image without changing aspect ratio the resized image size is 1472X828. then how can i feed this image to inference.

Can't Duplicate TAO results for Yolo V3 Inferencing

Here it is running trtexec like this: /usr/src/tensorrt/bin/trtexec --loadEngine=trt.engine --verbose Results are: &&&& RUNNING TensorRT.trtexec [TensorRT v8001] # /usr/src/tensorrt/bin/trtexec --loadEngine=trt.engine --verbose [11/01/2021-09:15:32] [I] === Model Options === [11/01/2021-09:15:32] [I] Format: * [11/01/2021-09:15:32] [I] Model: [11/01/2021-09:15:32] [I] Output: [11/01/2021-09:15:32] [I] === Build Options === [11/01/2021-09:15:32] [I] Max batch: 1 [11/01/2021-09:15:32] [I] Works…

YOLO v4 inference with TensorRT after training with TLT 3.0

Here is the full script (it’s quite basic): import tensorrt as trt TRT_LOGGER = trt.Logger(trt.Logger.VERBOSE) trt.init_libnvinfer_plugins(TRT_LOGGER,'') DTYPE_TRT = trt.float32 import pycuda.driver as cuda import pycuda.autoinit from PIL import Image import numpy as np path_img = "image.jpg" offsets = ( 103.939, 116.779, 123.68 ) yolo_reso = (3, 768, 1024) # Simple helper data class that's a little nicer to use than a 2-tuple # from TRT Python sample code class HostDeviceMem(object): de…

Doing inference in python with YOLO V4 in TensorRT - postporsessing

Ok, with your recomendations i found a workinkg example of inferring with yolo v4. But i still have some issues: The model im using is custom YOLO v4 trained with our own dataset. With the example of TLT (tlt_vc_samples_v1.1.0/yolo_v4/yolo_v4.ipynb). It is trained for Person, Car and Two_wheels. Model: trt2-yolo.engine - Google Drive For exporting the model we use: !tlt yolo_v4 export -m $USER_EXPERIMENT_DIR/experiment_dir_unpruned/weights/yolov4_resnet18_epoch_080.tlt \ …
