This seemed to solve the problem for me (setting --layout = nhwc->nchw)
My NN doesn't seem to be working on the Camera, however this could be due to something else (to be investigated)
Here is my full blob_path
blob_path = blobconverter.from_tf(
frozen_pb="./frozen_graph.pb",
data_type="FP16",
shaves=6,
optimizer_params=[
f"--input_shape=[1,{SHAPE},{SHAPE},3]",
"--layout=nhwc->nchw"
]
)
