    // TensorFlow convolution op only has two inputs, while the TFLite one has
    // three, with the bias vector marked as optional. However, TOCO has a
    // dedicated pass, EnsureBiasVectors, to create default bias vectors for all
    // those missing. So we model TFLite convolution op as requiring three
