> Is Identity operator not supported?

While submitting I am constantly getting:

The TFLite model was generated using TF 1.15.0 runtime and without the experimental converter by setting `converter.experimental_new_converter = False`. Could you folks please provide some information on this?

Hi Sayak,

tf.identity is supported in TFLite. However, the tf.identity_n you reported here is not supported by TFLite.
Please find bellow for the ops compatibility of TFLite. Thank you.

Is it when we try running inference? Because the conversion works perfectly fine.
