Have you tried https://github.com/PINTO0309/json2onnx?

Thanks, I have. It's part of the big package simple-onnx-processing-tools(v1.1.16). I'm not that familiar with Python, so I couldn't get into it. Apparently this is a separate and not very simple topic. It takes time.

Thanks, I've seen it. It is part of the big package simple-onnx-processing-tools(v1.1.16). I'm not that familiar with Python, so I couldn't get into it. Apparently this is a separate and not very simple topic. It takes time.

I also came across such variants:

Am I right to understand that there is nothing at all in R with conversion to ONNX? My searches in this direction did not lead to anything.

Can the ChatGPT generate R code to convert JSON to ONNX?

-

Yes, I can help generate R code to convert JSON to ONNX.

First, you will need to have the required R packages installed, including "jsonlite" and "onnx". You can install these packages using the following commands in R:

install.packages("jsonlite")
install.packages("onnx")

Assuming you have a JSON file with the data you want to convert to ONNX, you can use the following R code to load the JSON data, convert it to a data frame, and then convert it to ONNX:

library(jsonlite)
library(onnx)

#  Load the JSON data from file
json_data <- fromJSON("path/to/json/file.json")

#  Convert the JSON data to a data frame
df <- as.data.frame(json_data)

#  Convert the data frame to ONNX
onnx_model <- convertToONNX(df, "model_name")

#  Save the ONNX model to file
saveONNXModel(onnx_model, "path/to/onnx/model.onnx")

In the above code, replace "path/to/json/file.json" with the actual path to your JSON file, "model_name" with the name you want to give your ONNX model, and "path/to/onnx/model.onnx" with the desired path and file name for your ONNX model.

This code assumes that your JSON data is in a format that can be easily converted to a data frame, such as a JSON array of objects. If your JSON data is in a more complex format, you may need to do additional data manipulation before converting it to ONNX.

How childishly naive

Tell ChatGPT that the functions convertToONNX() and saveONNXModel() are not in the onnx package) Here is its description. ChatGPT will of course apologise and lie the next option) Already checked.

In idea you can generalise the question or make it in several steps, but it's not for me, it's easier to search.

https://github.com/PINTO0309/json2onnx/blob/main/json2onnx/json2onnx.py

The basic code is kind of short

#  Convert JSON to onnx model
    onnx_str = json.dumps(json_file)
    onnx_graph = Parse(onnx_str, onnx.ModelProto())

It's python. My original question was about R.

The gulf in competence between people on the forum is so deep that some posts sound like mockery

I've basically started reversing the file format. Everything I've come across before says it's a json compressed protobuf. I just found this: "The ONNX-formatted model is a Protocol Buffers file, which is a message file format developed by Google"
