树莓派4B+ python 3.7.3

利用yolov3 【608，608】 生成 model.nb

执行如下程序

from paddlelite.lite import * from PIL import Image import numpy as np

设置config信息

config = MobileConfig() config.set_model_from_file("model.np")

创建predictor

predictor = create_paddle_predictor(config)

从图片读入数据

image = Image.open('test.jpg') resized_image = image.resize((608, 608), Image.BILINEAR) image_data = np.array(resized_image).flatten().tolist()

设置输入数据

input_tensor = predictor.get_input(0) input_tensor.resize([1, 3, 608 608]) input_tensor.set_float_data(image_data)

执行预测

predictor.run()

得到输出数据

output_tensor = predictor.get_output(0) print(output_tensor.shape()) print(output_tensor.float_data()[:10])

错误代码

Backend terminated or disconnected.Fatal Python error: Segmentation fault
