X Cube AI Internal Error: Trying to remove _lstm_layer_detail_LSTM_output_1 which has multiple inputs

[ERICWU]

Hi,

I tried to deploy a LSTM model on stm32h747i-disco board. However, I met "
INTERNAL ERROR: Trying to remove _lstm_layer_detail_LSTM_output_1 which has multiple inputs" when I used x-cube-ai to analyse the model. 

I am wondering what should I do to solve this problem and why it has this problem.

Thanks.

Hello @ERICWU 

Sorry for the late answer, your post was moved to this topic a few minutes ago.

As of today, LSTM are badly supported, it should be part of the focus in the release after the next one.

Could you share your model please?

You have the list conditions to use LTSM here:

ONNX toolbox support

TensorFlow Lite toolbox support

Have a good day,

Julian
