What's the next step after build the onnxruntime from source code

[rayeh5]

I follow the "Build ONNX Runtime" on Ubuntu 16.04 environment with the following commands:
git clone --recursive https://github.com/Microsoft/onnxruntime
cd onnxruntime
./build.sh --config RelWithDebInfo --build_wheel
The build is successful, and start to run the tests.
Since the tests stay for a long time, so I use CTRL-C to break it.

Now, I am trying to use the pre-trained model to run this onnx runtime.
But I can't find any useful information to run it.

The example is using Python to import the onnx_runtime.
I have no idea which file and where is needed for the Python program to import it.
Where can I find the related information?

Thanks for your time.

It seems that "CTRL-C" will break the build process, cause incomplete build.
I modify the test program to pass the "long" test, and can build to complete.
Will try again to learn how to run the onnx_runtime.

Under the build/Linux/RelWithDebInfo/dist, there are two whl files: onnxruntime-0.1.5-cp35-cp35m-linux_x86_64.whl and onnxruntime-0.1.5-cp35-cp35m-manylinuxlinux1_x86_64.whl.
I use the command: pip3 install xxx.whl

After type python3

import onnxruntime.backend as backend
I got error message:
ImportError: No module named 'onnx'

Is something wrong for the building or install process?

Thanks for your time.

In order to use onnxruntime python package, you need to install onnx python package first.

Thanks!
Now "import onnxruntime.backend as backend" is successful.
I also download the mnist model.

But I can't find any useful python code to run this model.
Could someone help to let me know where I can find the example code to run a model via python or C, etc.

Thanks for your time.

Here's one example from this page

# Compute the prediction with ONNX Runtime
import onnxruntime as rt
import numpy
sess = rt.InferenceSession("rf_iris.onnx")
input_name = sess.get_inputs()[0].name
label_name = sess.get_outputs()[0].name
pred_onx = sess.run([label_name], {input_name: X_test.astype(numpy.float32)})[0]

hi @pranavsharma @snnn
after building onnx successfully, I still can not import onnxruntime as below error:
ImportError: No module named 'onnxruntime'

could you check and give me your comment

I did pip3 install onnxruntime (if you are on a different OS it might be different i.e. linux flavor). Then I get an error "cannot import name 'get_all_providers' from 'onnxruntime.capi._pybind_state"

Which will take you to here: #4196

I have not completed the steps to see if it will solve the issue or not yet but putting this here in case others end up here eventually. In the issue template the user mentions System Information as: OS Platform and Distribution (e.g., Linux Ubuntu 16.04): Windows 10. So if you are in those OS you might look into the above link if your issue is as mine.

I have same issue as @hoaquocphan
