Error when converting Keras ConvLSTM2D layer into ONNX

[YizhouFan]

My code snippet for conversion:

MODEL_NAME = "data/pie/intention/context_loc_pretrained/model"
model = load_model(MODEL_NAME + ".h5")
onnx_model = keras2onnx.convert_keras(model, model.name, target_opset=14)
temp_model_file = MODEL_NAME + ".onnx"
onnx.save_model(onnx_model, temp_model_file)

Error message:

ValueError: Unable to find out a correct type for tensor type = 0 of conv_lst_m2d_1/while/TensorArrayWrite/TensorArrayWriteV3/Enter:0

Happens to me too.
Any updates about this?
