input: Assertion 'inputs_.size()==1' failed.Aborted

[tianfei]

  I build a 3-layers convolution network with tensorflow only containing "Conv+BN+Relu" structure.

  I got an "../onnx_v1.6.0/onnx/common/ir.h:512: input: Assertion `inputs_.size() == 1` failed.Aborted' failed.Aborted"  error when I run this model on apex  after saving it as .pb file and quantify it. 

  My pb file has been uploaded as attach.

As far as I know onnx_v.1.1.0 is supported nativelly.
So please try some version elder than 1.6.0 one. It may help.
