in DFUT version check for Ubuntu Comment by Maria Chen April 2024

Hi Yuchen, Unfortunately, we can't remove the version check. If you are using a version that's not 18.04, you could build your own DFUT console instead of using the pre-built DFUT GUI. Step1: Download the latest PLUS here: https://www.kneron.com/tw…

Hi Youngjun, Yes, you could try converting the keras model to onnx with keras2onnx. There's also tensorflow-onnx that you could use if you could convert the keras model to tf: https://github.com/onnx/tensorflow-onnx

in Keras Model (Movinet) to nef conversion Comment by Maria Chen April 2024

Hi Youngjun, We would recommend you to convert the hdf5 file into an onnx file by using a third-party program instead of keras2onnx, then continue the nef conversion flow with that onnx file.
