Convertion error due to missing bias

Hi all,

I'm trying to convert a model with snpe-tensorflow-to-dlc but I'm getting the following error:

ERROR - Conversion failed: ERROR_TF_CONV_RESOLVE_BIAS: Cannot resolve convolution layer due to missing bias after operation: CNN/CNN_conv
 

Is there a way to convert a layer that does not have bias?

Thanks in advance

Hi, I meet this problem before, here is my solution:

Modify get_biases () function in ~/snpe/lib/python/converters/tensorflow/layers/convolution.py :

    def get_biases(self, graph_helper, conv_op, bias_op):
        _, biases_tensor = GraphHelper.get_op_input_tensors(bias_op, ('?', '?'))
        if biases_tensor.op.type not in ['Identity', 'Const']:
            # raise ConverterError(code_to_message.get_message('ERROR_TF_CONV_RESOLVE_BIAS')(conv_op.name))
            biases = None
        else:
            biases = graph_helper.evaluate_tensor_output(biases_tensor)
        return biases
 
 
I hope this will help you.
