Hi there,
I’m Leo, ML GDE from Mainland China. Months ago, I’ve tried tflite for microcontroller with OpenMV H7 3 but face some issues:
when converter.optimizations = [tf.lite.Optimize.DEFAULT] is set. it raises “hybrid model is not supposed” or converter.target_spec.supported_ops = [tf.lite.OpsSet.TFLITE_BUILTINS_INT8] and follow are set, it raises “Currently, only float32 input type is supported.”
more information can be found here 3
I’m wondering if anyone meets the same issue or can someone kindly sharing the possible solution?
thanks in advance 
Leo
