The converted weight file does not have quantized layer

I use  the tool **assets/tflite_export.py** to convert **effcientvit_b1** to tflite, I noticed that in the function **TFLiteConverter**, the parameter **quantize_target_type** is set to the default value 'uint8'. However, the output weight file does not include quantized and dequantized layers; each layer is still in **float32** format."
