ORT的编译脚本:build.sh 最终是通过这个python脚本来完成的,具体编译可以分析这个脚本即可 onnx_runtime\onnx-runtime\tools\ci_build\build.py
model_def = helper.make_model(graph_def, producer_name='onnx-example') # 保存模型到文件 with open('model.onnx', 'wb') as f: f.write(model_def.SerializeToString()) ``` 2. 使用ONNX Runtime加载模型并进行推理: ```python import onnxruntime as ort # 初始化ONNX Runtime会话 sess =...
在同一台机器上,使用我上次的python版onnx脚本来测试相同文本,平均耗时是7.2ms左右。C++和python的ORT都是没有设置额外参数的,单就推理本身而言,其实C++版本的推理本身性能优势并不大。因为即使是python版ORT,它真正执行的推理后端也是C/C++编译产出的库,而非python直接进行推理。 这就有个疑惑了,既然如此,那么把模...
Defines the compute stream for the inference to run on. It implicitly sets thehas_user_compute_streamoption. It cannot be set throughUpdateCUDAProviderOptions, but ratherUpdateCUDAProviderOptionsWithValue. This cannot be used in combination with an external allocator. Example python usage: providers =...
# Get the first example data to run the model and export it to ONNX data = dataset[0] inputs = { 'input_ids': data[0].to(device).reshape(1, max_seq_length), 'attention_mask': data[1].to(device).reshape(1, max_seq_length), ...
Figure 1. ONNX Runtime high-level architecture Run a model with ONNX Runtime ONNX Runtime is compatible with most programming languages. As in the other post, this post uses Python for simplicity and readability. These examples are just meant to introduce the key ideas. For more information...
FOr example, on the information page for theMOBILENET V2 model, (from last week’s sample) you’ll find the following information along with sample Python code that shows an example of how to pre-process image data before sending to the model. ...
ONNXRuntime的Python接口进行推理主要分三步导入onnxruntime包创建InferenceSession,参数为需要进行推理的onnx义见下面的InferenceSession小节;用run方法进行推理,参数为输出列的名称list和输入的名称-输入值的dict,输入值的形状与模型能接受的形状相同,其他参数的含义见下面的Session.run小节。返回值是一个由ndarray组成...
在上文《实践演练Pytorch Bert模型转ONNX模型及预测》中,我们将Bert的Pytorch模型转换成ONNX模型,并使用onnxruntime-gpu完成了python版的ONNX模型预测。今天我们来把预测搬到C++上,模拟一下模型的部署。 对于C++版本模型预测服务,只需要按部就班完成如下三步即可: ...
