tensor example support

[KwansuKim]

It seems that it is not possible to use "github.com/galeone/tfgo/proto/example" from tfgo v2.9.
Are there any available ways to use example.Features and example.Example in tfgo v2.9?
Or could you let me know another way to feed saved models without them?

[galeone]

Isn't possible to use tf.NewTensor and feed it as input to the saved model?
I do this in the example you can see in the README.

Is this the thing you are looking for or do I misunderstand your question?

[galeone]

Now that I'm thinking about the proto/example thing clearly, I remember that I explicitly removed (a long time ago!) that part, because it's tensorflow itself that only supports SavedModels and the proto/example was there for feeding the estimators/frozen models. That type of model is not supported anymore by TensorFlow and therefore I removed them in this commit 132f4f1

You must use a SavedModel and feed the tensors using tf.NewTensor as shown in the readme

Thanks for quick answer! I'm gonna try it according to your comment.

@galeone Could you help me to resolve the below build issue?

[galeone]

You're using tensorflow, the official package - it's broken. You must use the fork I maintain instead:

github.com/galeone/tensorflow/tensorflow/go

As you can see the tf package in the example, comes from this package, not from the official one

@galeone How can I make a tensor to input a model in case a model's input values involve different types like string, float32 at the same time?
The following feature list is a sample I'd like to implement. With tensor.example, it would be possible to do it but now I'm not sure how to do it without tensor.example.
"feature_a": "string_1"
"feature_b": "string_2"
"feature_c": 34.23
"feature_d": [1.0, 2.0, 3.0, 4.0]
