when try predict

thanks for your awesome code .but when I try predict I got two errors the first is ("Error when checking input: expected conv2d_15_input to have shape (200, 200, 3) but got array with shape (200, 200, 4) ") and the second is that ("input' has DataType uint8 not in list of allowed values: float16, bfloat16, float32, float64 ")

Which particular notebook is this about? You need to put more details in your issue description.
