I am getting this error while converting .onno model into blob file.

Traceback (most recent call last):

    Hello ShahidHussain , not sure if this is related but I have also noticed an issue when converting onnx->blob, issue here. If it's not the same, please open a new issue on github.
    Thanks, Erik

        Hi heebahsaleem
        Your error seems to stem from the

        heebahsaleem "stderr": "Cannot get length of dynamic dimension\n",

        If your model has layers with dynamic or undefined dimensions, you might need to specify these dimensions explicitly before converting the model.

        Thanks,
        Jaka

            heebahsaleem

            Thanks, I added the dimensions and it solved it.
