I exported a Pytorch model to ONNX, but I cannot load it on the browser for inference.
Details about my problem:

ONNX version: 1.5.0
Python version: Python 3.6.7 :: Anaconda, Inc.
Browser: Google Chrome 75.0.3770.100
ONNX model: https://drive.google.com/file/d/16JIuHKmp9vA-CL_6z6l8KjwZ1Qcnf-Jz/view?usp=sharing

Code:

<html>
  <head> </head>

  <body>
    <!-- Load ONNX.js -->
    <script src="https://cdn.jsdelivr.net/npm/onnxjs/dist/onnx.min.js"></script>
    <!-- Code that consume ONNX.js -->
    <script>
       // Create an ONNX inference session with default backend.
       const session = new onnx.InferenceSession();
            
        // Load an ONNX model.
        session.loadModel("./NumberPredictor.onnx").then((success) => {
            console.log("success", success);
        }).catch((error) => {
            console.log("error", error);
        });
    </script>
  </body>
</html>

Same problem.

LSTM Op is not supported by ONNX.js yet.

Is it going to be supported in the future?

I also hope LSTM op can be supported by onnx.js
