Root Cause
Input tensor channel order doesnt match model expectation.
genericWorkarounds
-
90% success Set tf.keras.backend.set_image_data_format() to match model
-
88% success Use tf.transpose to convert: NHWC <-> NCHW
Dead Ends
Common approaches that don't work:
-
Transpose all inputs blindly
78% fail
Wrong axis for non-image data
-
Set global data_format without checking model
82% fail
Breaks pretrained weights
